[Title] Difficulty in establishing a diagnosis in an uncommon presentation of a minor salivary gland tumour.

We report the case of a man presenting with a large, airway obstructing, minor salivary gland tumour arising from the right tonsillar base.

A firm diagnosis of malignancy could not be made histologically.

The differential diagnosis included polymorphous low-grade adenocarcinoma, basal cell adenoma and adenoid cystic carcinoma.

However, on balance, based on the clinical presentation, a diagnosis of malignancy was favoured and appropriate treatment was considered.

[Title] Carbon ion radiotherapy for basal cell adenocarcinoma of the head and neck: preliminary report of six cases and review of the literature.

BACKGROUND: Basal cell adenocarcinoma accounts for approximately 1.6% of all salivary gland neoplasms.

METHODS: Case records of 6 patients with diagnosis of basal cell adenocarcinoma of the head and neck, who were treated by carbon ion radiotherapy with 64.0 GyE/16 fractions in our institution, were retrospectively reviewed.

CONCLUSIONS: Carbon ion radiotherapy should be considered as an appropriate curative approach for treatment of basal cell adenocarcinoma in certain cases, particularly in cases of unresectable disease and postoperative gross residual or recurrent disease.

[Title] Basal cell adenoma of the parotid gland. Case report and review of the literature.

Basal cell adenoma of the salivary glands is an uncommon type of monomorphous adenoma.

Its most frequent location is the parotid gland.

Histologically, isomorphic cells in nests and interlaced trabecules with a prominent basal membrane are observed.

It is also characterized by the presence of a slack and hyaline stroma and the absence of myxoid or condroid stroma.

Due to prognostic implications, differential diagnosis with basal cell adenocarcinoma, adenoid cystic carcinoma and basaloid squamous cell carcinoma is mandatory.

We describe a case of basal cell adenoma of the parotid gland.

We also review the literature and discuss the diagnosis and management of this rare entity.

[Title] Bilateral Basal cell adenocarcinoma of the parotid gland: in a recipient of kidney transplant.

We report a rare case of bilateral basal cell adenocarcinoma (BcAC) of the parotid gland in a male patient 30 years after kidney transplantation and continuous administration of immunosuppressive therapy.

BcAC is a salivary gland malignancy first recognized as a distinct neoplastic entity in WHO classification of salivary gland tumours in 1991.

Over 90% of BcACs are detected in the parotid gland.

The most important differential diagnosis is basal cell adenoma.

[Title] Basal cell adenocarcinoma of a hard palate minor salivary gland: case report and review of the literature.

OBJECTIVE: Basal cell adenocarcinoma of a minor salivary gland is extremely rare.

The goal of this report is to increase awareness of this rare disease and to review and discuss the differential diagnosis and important considerations in treatment.

METHODS: Case report of a basal cell adenocarcinoma of a hard palate minor salivary gland and review of the literature of basal cell adenocarcinoma.

RESULTS: Basal cell adenocarcinomas are slow-growing tumours that most commonly involve the parotid gland and very rarely involve minor salivary glands.

Histological diagnosis is important to distinguish this tumour from adenoid cystic carcinoma given the significant difference in disease prognosis.

CONCLUSIONS: Diagnosis of these tumours must be made histologically.

[Title] Basal cell adenocarcinoma of minor salivary glands.

Basal cell adenocarcinoma of minor salivary glands is a relatively rare slow-growing tumor with an infiltrating growth pattern.

The infiltrating growth pattern and likelihood of vascular and perineural involvement distinguishes basal cell adenocarcinoma from basal cell adenoma.

Basal cell adenocarcinomas show strong immunoreactivity to cytokeratin 7 and variable myoepithelial staining with S100.

It is necessary to differentiate basal cell adenocarcinoma from other basaloid cell tumors of the minor salivary glands because of the prognosis and potential differences in treatment, particularly adenoid cystic adenocarcinoma and basaloid squamous carcinoma.

Surgical excision with a wide margin to ensure complete removal has been suggested as the primary treatment for basal cell adenocarcinoma.

Radiotherapy has been proposed for lesions in the minor salivary glands because of the higher likelihood of vascular and neural invasion and for those that are diffusely infiltrative.

[Title] Basal cell adenocarcinoma of the ethmoid sinuses.

Basal cell adenocarcinoma is a rare and relatively recently characterised malignant salivary gland tumour.

It accounts for 5 per cent of parotid gland tumours and 1 per cent of salivary gland malignancies.

It is very rarely documented in anatomical sites other than the major salivary glands.

Basal cell adenocarcinoma has only been described once before in the ethmoid sinus.

We report a case of basal cell adenocarcinoma in the ethmoid sinus, extending into the right orbit and anterior cranial fossa.

We describe the clinical aspects of the patient's management and detail the histopathological features of this very rare diagnosis.

[Title] Cytogenetic and fluorescence in situ hybridization analysis of a basal cell adenocarcinoma of the mandible.

Basal cell adenocarcinoma (BCAC) of the salivary glands is rare.

Distant metastasis to the mandible from a salivary gland tumor is also considered rare.

The cytogenetic finding of a case of metastatic BCAC of the mandible is described.

An 80-year-old female with primary BCAC of the parotid salivary gland underwent parotidectomy and chemotherapy.

The characteristic histologic architecture of BCAC found in the mandible was similar to that of the earlier findings of the tumor in the parotid gland.

[Title] Basal cell adenocarcinoma of the oral minor salivary glands: review of the literature and presentation of two cases.

Basal cell adenocarcinoma (BCA) is an unusual salivary gland malignancy that very rarely affects the minor glands.

Here we present 2 cases of BCA arising in the minor salivary glands of the left cheek and junction of the hard and soft palate, respectively.

A comprehensive literature review revealed only 21 previously reported cases of BCA of oral minor salivary glands.

This is an exceptionally rare salivary gland tumor, which, despite its low-grade behavior, demands complete surgical removal with adequate margins.

Immunohistochemical studies may complement a thorough histopathologic analysis in discriminating BCA from other salivary gland tumors.

A distinctive variant of basal cell adenoma called membranous basal cell adenoma is well recognized in salivary glands.

We present a case of a tumor involving the parotid gland that appeared identical to cutaneous spiradenoma.

In addition, the lesion had a malignant component identical to basal cell adenocarcinoma.

This is the first report of a "dermal analogue tumor" of the salivary gland that resembled a cutaneous spiradenoma and not a cylindroma.

[Title] Fine-needle aspiration cytology of basal cell adenoma of the parotid gland: characteristic cytological features and diagnostic pitfalls.

We retrospectively studied the cytological features of aspiration cytology in 12 cases of basal cell adenoma (BCA) and 5 cases mistakenly diagnosed as BCA.

The characteristic cytological features of solid type BCA were three-dimensional clusters in 71%, sharp-angle small clusters in 86%, basement membrane- like material in 71%, and cell crush in 86%.

In contrast, 3 of the 5 cystic type BCA cases showed inadequate cellular components or no basaloid tumor cells, and the cytological diagnosis of BCA could not be determined.

In the 5 cases misdiagnosed as BCA, there were 2 cases of pleomorphic adenoma, 2 cases of benign lymphoepithelial cyst, and 1 case of basal cell adenocarcinoma.

Accurate differential cytological diagnosis of BCA is relatively easy to determine the solid type BCA, but is more difficult for cystic type BCA.

[Title] Diagnostic difficulties in the interpretation of fine needle aspirate samples in salivary lesions: diagnostic pitfalls revisited.

OBJECTIVE: To present our experience in diagnostic errors and pitfalls on aspiration cytology of salivary region in a high volume of cases.

STUDY DESIGN: In a retrospective review of cytology files of a head and neck referral center from 1990 to 2005, the false positive and false negative interpretations on fine needle aspiration (FNA) of salivary lesions were retrieved.

These records and slides were reviewed to identify cytologic characteristics that contributed to false diagnosis.

RESULTS: Of a total of 1,040 salivary FNA samples, 376 cases had a final histologic diagnosis with interpretations of benign or malignant.

The most common false negative cases were acinic cell carcinoma, epithelial myoepithelial carcinoma, adenoid cystic carcinoma and basal cell adenocarcinoma.

Benign cases with false positive diagnosis were Warthin tumor and pleomorphic adenoma.

CONCLUSION: Knowledge of cytologic overlaps and pitfalls on salivary gland FNA, as well as clinical and radiologic features, may help clinicians arrive at the appropriate diagnosis and reduce false interpretations.

CD43 immunoreactivity with 2 different antibodies was detected mainly in ACC but also 1 membranous type basal cell adenocarcinoma and 1 colonic adenocarcinoma.

Nine of 20 (45%) ACC (8/17 salivary/mucoserous and 1/3 mammary) showed immunoreactivity with clone MT1 whereas 4 (23.5%) salivary ACC also showed immunoreactivity with clone DF-T1.

Hence, CD43 seems to be selectively expressed in a subset of ACC and its significance in salivary tumors is discussed.

INTRODUCTION: Basal cell adenoma (BCA) is a rare benign neoplasm characterized by the basaloid appearance of the tumour cells and the lack of myxo-chondroid stromal component present in pleomorphic adenoma.

AIM: We report a case of basal cell adenoma of membranous type, highly suspected of malignancy because of the presence of mediastinal lymph nodes and pulmonary nodules which finally were related to an associated sarcoidosis.

So the diagnosis of metastatic malignant salivary gland tumor was suspected.

Finally, the histological examination concluded to a basal cell adenoma of membranous type with sarcoidosis granulomas in the parotid and in the lymph nodes.

CONCLUSION: The BCA is a benign tumor located generally in the parotid gland.

When the malignancy is suspected, like in our case, this tumor must be differentiated from the basal cell adenocarcinoma using histological criteria.

[Title] Atypical presentation of oral basaloid squamous cell carcinoma.

AIM: The purpose of this report is to present the clinical and histological features of a basaloid squamous cell carcinoma (BSCC) occurring in the retromolar trigone of a 59-year-old man and to relate its immunohistochemical characteristics.

BACKGROUND: BSCC is an aggressive distinct variant of squamous cell carcinoma (SCC) requiring recognition as a separate entity from SCC due to its peculiar behavior.

SUMMARY: Since this tumor can mimic other neoplasms such as adenoid cystic carcinoma, neuroendocrine carcinoma, and basal cell adenocarcinoma, histological features are essential to differentiate between them.

Clinicians are advised to conduct a mucosal evaluation during oral examinations and take a thorough medical history which could ultimately save the life of a patient.

[Title] Malignant salivary gland tumors and cyclo-oxygenase-2: a histopathological and immunohistochemical analysis with implications on histogenesis.

The classification system for malignant salivary gland tumors (MST) is largely dependent on its histogenesis.

Fifty six primary major and minor gland MST were stained with anti-cox-2 antibody and rated with a combined score that added a scale of intensity to the percentage of tumor cells that overexpressed the cox-2 protein.

Strong cox-2 overexpression was noted in all MST of proposed excretory duct origin: salivary duct carcinoma (100%), mucoepidermoid carcinoma (MEC) (92%), and adenocarcinoma nos (AdC nos) (83%).

Primary squamous cell carcinoma (PSCC) was the exception.

Negative expression was noted in all tumors of proposed intercalated duct origin (adenoid cystic carcinoma, basal cell adenocarcinoma and acinic cell carcinoma) with the exception of one case of polymorphous low grade adenocarcinoma.

Strong cox-2 overexpression was noted in the epidermoid cells of MEC, abluminal duct cells surrounding the duct-like structures and ductal cells of AdC nos and salivary duct carcinoma.

[Title] Fine needle aspiration cytology of basal cell adenoma of the salivary gland.

OBJECTIVE: To formulate cytologic features for differential diagnosis of basal cell adenoma (BCA).

STUDY DESIGN: The usefulness of 5 items for a cytologically definitive diagnosis of BCA was examined.

The 5 items in 8 BCA and 22 non-BCA cases (adenoid cystic carcinoma [ADCC], basal cell adenocarcinoma, myoepithelioma, pleomorphic adenoma and polymorphous low-grade adenocarcinoma) that displayed mimicking cytology were examined cytologically.

RESULTS: The useful items were < 5.1 microm in mean of epithelial nuclear short diameter; mild atypia on definitive diagnosis; stromal cell cluster combining smooth margin surrounding the epithelial cell cluster or containing the epithelial cell cluster; epithelial clusters surrounded by or adhered to a thick, hyalinized smooth margin without stromal cluster; and closely fastened, tight clusters with denser cytoplasm than ADCC, but an indistinct border, with oval nuclei and no hyaline cells.

[Title] Intraoral minor salivary gland tumors: a clinicopathological study of 82 cases.

We present a retrospective study of 82 patients with intraoral minor salivary gland tumors which were diagnosed from 1979 to 2003 in Gifu University Hospital.

Histologically, the tumors were classified as pleomorphic adenoma (n = 54), papillary cystadenoma (n = 1), adenoid cystic carcinoma (n = 10), mucoepidermoid carcinoma (n = 8), acinic cell carcinoma (n = 3), adenocarcinoma (n = 2), basal cell adenocarcinoma (n = 1), papillary cystadenocarcinoma (n = 1), and carcinoma in pleomorphic adenoma (n = 2).

From the results of the present study and review of the literature, it is suggested that the minor salivary gland tumors in Japan may be characterized by a higher incidence of benign tumors, especially of pleomorphic adenoma; a more marked tendency for female predominance; a higher incidence of palatal involvement; and a rarer occurrence of polymorphous low grade adenocarcinoma, in comparison with those reported in the literature from outside of Japan.

[Title] Comparative examination of androgen receptor reactivity for differential diagnosis of sebaceous carcinoma from squamous cell and basal cell carcinoma.

Early diagnosis and proper treatment significantly improve the outcome.

SEB should be differentiated histopathologically from basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).

Along with other markers and morphologic features, AR can be helpful in the diagnosis of SEB and its differentiation from SCC and BCC.

[Title] Atypical sclerosing adenosis of the prostate: a rare mimic of adenocarcinoma.

AIMS: Sclerosing adenosis of the prostate is a benign, small, acinar proliferation in dense spindle cell stroma, with a distinct immunohistochemical profiles.

METHODS AND RESULTS: We describe five cases of sclerosing adenosis with significant cytological atypia, referred to as atypical sclerosing adenosis (ASA), which were initially considered suspicious or diagnostic of adenocarcinoma.

All cases of typical and atypical sclerosing adenosis displayed an intact basal cell layer, which was immunoreactive for high-molecular-weight keratin, S100 protein, smooth muscle actin, and prostate-specific antigen, with no differences between ASA and the control group.

CONCLUSIONS: ASA is an unusual small, acinar proliferation of the prostate that may be mistaken for adenocarcinoma, and should be distinguished from other mimics, including atypical adenomatous hyperplasia, mesonephric remnant hyperplasia, and post-atrophic hyperplasia.

[Title] A novel lung metastasis signature links Wnt signaling with cancer cell self-renewal and epithelial-mesenchymal transition in basal-like breast cancer.

In epithelial cancers, such as those of the breast, the epithelial-mesenchymal transition (EMT) is associated with basal-like breast cancers, generates cells with stem-like properties, and enables cancer cell dissemination and metastasis.

However, the molecular mechanism(s) that connects stem cell-like characteristics with EMT has yet to be defined.

The wnt genes identified in this signature were strongly associated with human basal-like breast cancers.

Collectively, these results provide a molecular link between self-renewal, EMT, and metastasis in basal-like breast cancers.

[Title] Simultaneous exposure to dietary acrylamide and corn oil developed carcinogenesis through cell proliferation and inhibition of apoptosis by regulating p53-mediated mitochondria-dependent signaling pathway.

Colonic apoptosis and cell proliferation, expression of Wild type (wt) p53, Bcl-2, Bax and caspase-3, were detected at 48 week post ACR-exposure.

Apoptosis was decreased and cell proliferation was increased in colonic mucosa in ACR-treated rats on dietary corn oil compared to vehicle rats on basal diet (P < 0.05).

[Title] Ductal adenocarcinoma of the prostate: current opinion and controversies.

OBJECTIVE: To evaluate the morphologic spectrum and clinical significance of ductal adenocarcinoma of the prostate (DAP).

STUDY DESIGN: We reviewed diagnostic criteria, including the value of immunohistochemistry, and outlined the prognostic implications of a diagnosis of DAP.

A basal cell layer can be seen in some of these tumors, which is probably due to tumor growth into preexisting ducts.

CONCLUSION: DAP are neoplasms of prostatic origin, and the terms endometrioid or endometrial adenocarcinoma are best avoided.

DAP are aggressive tumors with a shortened average time to progression compared with acinar adenocarcinoma.

[Title] Somatostatin inhibits colon cancer cell growth through cyclooxygenase-2 downregulation.

BACKGROUND AND PURPOSE: Cyclooxygenase-2 (COX-2) is expressed in colonic neoplasms, where it supports cell proliferation via prostaglandin E(2) (PGE(2)) production.

EXPERIMENTAL APPROACH: Human colon adenocarcinoma cell lines Caco-2, HT-29 and HCT116 were used.

The following techniques were employed: colourimetric assay for cell growth; 5-bromo-2'-deoxyuridine assay for DNA synthesis; enzyme immunoassay for PGE(2); COX-2 mRNA silencing; RT-PCR or Western blot for somatostatin receptor subtypes, cyclooxygenase isoforms, phosphorylated-ERK-1/ERK-2 and phosphorylated-Akt.

Somatostatin-14 inhibited basal COX-2 expression, PGE(2) production, DNA synthesis and growth in Caco-2 cells and these effects were prevented by BN81658 (sst(3) receptor antagonist).

Basal proliferation of HT-29, HCT116 and COX-2-silenced Caco-2 cells was not affected by somatostatin-14.

Stimulation of HT-29 cells with gastrin-17 elicited increments of ERK-1/ERK-2 and Akt phosphorylation, COX-2 expression, PGE(2) production, DNA synthesis and cell growth, which were all counteracted by somatostatin-14.

CONCLUSIONS AND IMPLICATIONS: Somatostatin decreases COX-2 expression and function in colon cancer cells via activation of sst(3) or sst(5) receptors, and these effects contribute to the inhibitory action of somatostatin on cell proliferation.

[Title] Periostin, secreted from stromal cells, has biphasic effect on cell migration and correlates with the epithelial to mesenchymal transition of human pancreatic cancer cells.

Periostin is a secretory protein that has been suggested to function as a cell adhesion molecule and promote the invasiveness or growth rate of tumors.

However, little is known about the association of its expression and epithelial to mesenchymal transition (EMT), which is considered to play a crucial role in cancer cell metastasis.

In vitro, pancreatic stellate cells (PSCs) exhibited a much higher basal expression of periostin compared with cancer cells.

To assess the direct role of periostin in pancreatic cancer cells, the authors generated pancreatic cancer cell lines that stably express periostin.

The induced expression of periostin (to 150 ng/ml) altered the morphology of cancer cells, changing them from mesenchymal to epithelial phenotypes with the induction of epithelial markers and a reduction of mesenchymal markers, and showed reduced cell migration in vitro and formed smaller tumors as well as suppressed metastasis in vivo.

On the other hand, high concentration of recombinant periostin (1 microg/ml) promoted cell migration with AKT activation.

[Title] Hierarchical cluster analysis of myoepithelial/basal cell markers in adenoid cystic carcinoma and polymorphous low-grade adenocarcinoma.

Distinguishing adenoid cystic carcinoma from polymorphous low-grade adenocarcinoma of the salivary glands is important for their management.

We studied the expression of several myoepithelial and basal/stem cell markers (smooth muscle actin, calponin, smooth muscle myosin heavy chain, metallothionein, maspin, and p63) by immunohistochemistry in 23 adenoid cystic carcinoma and 24 polymorphous low-grade adenocarcinoma, to identify the most useful marker or combination of markers that may help their diagnoses.

We noted diffuse expression of smooth muscle actin in 20 adenoid cystic carcinoma vs one polymorphous low-grade adenocarcinoma (P<0.0001), calponin in 15 adenoid cystic carcinoma vs one polymorphous low-grade adenocarcinoma (P<0.0001), smooth muscle myosin heavy chain in 15 adenoid cystic carcinoma vs one polymorphous low-grade adenocarcinoma (P=0.001), metallothionein in 22 adenoid cystic carcinoma vs eight polymorphous low-grade adenocarcinoma (P<0.001), maspin in 22 adenoid cystic carcinoma vs 14 polymorphous low-grade adenocarcinoma, and p63 in 21 adenoid cystic carcinoma vs 14 polymorphous low-grade adenocarcinoma.

In differentiating adenoid cystic carcinoma from polymorphous low-grade adenocarcinoma, smooth muscle actin as a single ancillary test in support of the histological findings, appears to be as efficient as multiple immunohistochemical tests.

[Title] [Koumine-induced apoptosis of human colonic adenocarcinoma cells: the cell biological mechanism].

OBJECTIVE: To investigate the cell biological mechanism of koumine-induced apoptosis of human colonic adenocarcinoma cells.

METHODS: The effects of LoVo cell koumine on the membrane potential, mitochondrial membrane potential, concentration of cytosolic free calcium, reactive oxygen species (ROS) and gap junctional intercellular communication was observed by laser scanning confocal microscopy.

RESULTS AND CONCLUSION: Koumine lowered the membrane potential and mitochondrial membrane potential of LoVo cells and decreased the concentration of free cytosolic calcium, which was increased to a level higher than the basal one after addition of EDTA.

These findings may explain the possible mechanisms of koumine-induced LoVo cell apoptosis.

[Title] Stratified epithelium in prostatic adenocarcinoma: a mimic of high-grade prostatic intraepithelial neoplasia.

Typically glands of prostatic adenocarcinoma have a single cell lining, although stratification can be seen in invasive carcinomas with a cribriform architecture, including ductal carcinoma.

The histomorphological features and immunohistochemical profile of cases of non-cribriform prostatic adenocarcinoma with stratified malignant glandular epithelium were analyzed.

These cases were identified from needle biopsy cases from the consultation files of one of the authors and from a review of 150 consecutive in-house needle biopsy cases of prostatic adenocarcinoma.

The main attribute in all these foci was the presence of glandular profiles lined by several layers of epithelial cells with cytological and architectural features resembling flat or tufted high-grade prostatic intraepithelial neoplasia, but lacking basal cells as confirmed by negative 34betaE12 and/or p63 immunostains in all cases.

The AMACR staining profile of the stratified foci was variable, with 4 foci showing positivity, and 3 foci being negative, including two cases that displayed AMACR positivity in adjacent non-stratified prostatic adenocarcinoma.

Prostatic adenocarcinoma with stratified malignant glandular epithelium can be identified in prostate needle biopsy samples harboring non-cribriform prostatic adenocarcinoma and resembles glands with high-grade prostatic intraepithelial neoplasia.

Recognition of this pattern of prostatic adenocarcinoma is necessary to correctly diagnose such cases as invasive carcinoma.

[Title] Peripheral myelin protein 22 is in complex with alpha6beta4 integrin, and its absence alters the Schwann cell basal lamina.

In the absence of PMP22, myelination of peripheral nerves is delayed, and numerous axon-SC profiles show loose basal lamina, suggesting altered interactions of the glial cells with the extracellular matrix.

The levels of beta4 integrin, a molecule involved in the linkage between SCs and the basal lamina, are severely reduced in nerves of PMP22-deficient mice.

During early stages of myelination, PMP22 and beta4 integrin are coexpressed at the cell surface and can be coimmunoprecipitated together with laminin and alpha6 integrin.

[Title] Differences in the structural features of atypical adenomatous hyperplasia and low-grade prostatic adenocarcinoma.

AIM: Atypical adenomatous hyperplasia (AAH) is a small glandular proliferation that has histological similarities with Gleason grade 1 and 2 prostatic adenocarcinoma (PACG1,2).

Basal cell-specific antikeratin was applied to these lesions.

We assumed that PACG1,2 lesions did have not basal cells and we grouped the lesions as AAH and PACG1,2 based on this assumption.

RESULTS: We found differences between AAH and PACG1,2 lesions for some parameters including the number of glands, structures such as the main ductus and basal cells.

We found similar properties in the two lesions for the following parameters: localization, multiplicity, diameter of the lesion, focus asymmetry, distance between glands, inflammatory cells in and out of the lesions, secretory cell shape on the luminal side, papillary projection towards the luminal side of gland, the shape of the outer gland, the infiltrative pattern of the gland, glandular pleomorphism, biggest gland diameter and median gland diameter.

[Title] AlphaB-crystallin: a novel marker of invasive basal-like and metaplastic breast carcinomas.

Basal-like tumors are a newly recognized estrogen receptor (ER) negative and HER2 negative breast cancer subtype that express basal epithelial genes and are associated with poor survival.

Metaplastic carcinomas are thought to belong within the basal-like group.

We have recently demonstrated that the small heat shock protein alphaB-crystallin is commonly expressed in basal-like tumors and contributes to their aggressive phenotype.

The current study examined the rates and patterns of alphaB-crystallin expression in whole tissue sections of human breast, including normal tissue, proliferative lesions, in situ and invasive carcinomas (ER positive, HER2 positive, basal-like, and metaplastic cancers).

In normal breast tissue, proliferative lesions and in situ carcinomas, alphaB-crystallin expression was restricted to the myoepithelial cell compartment of ductal and lobular units.

Most basal-like and metaplastic carcinomas demonstrated cytoplasmic expression of alphaB-crystallin (81% and 86%, respectively).

Taken together, our results indicate that alphaB-crystallin is a sensitive (81%) and specific (100%) marker for basal-like breast carcinomas.

Moreover, the high rates of expression of alphaB-crystallin in metaplastic breast carcinomas (86%) suggest that these tumors may represent a histologically distinctive subset of basal-like breast tumors with a similar underlying molecular etiology.

[Title] Basaloid adenocarcinoma. A new variant of pulmonary adenocarcinoma.

The 2004 WHO classification of lung tumours recognised basaloid carcinoma as a variant of squamous and large cell carcinoma.

We report a unique case of primary pulmonary adenocarcinoma with a basaloid component.

The patient is disease-free 13 months after diagnosis.

The former was an adenocarcinoma with mucus containing spaces lined by columnar mucinous cells and basaloid cells.

The solid component was an organoid proliferation of basaloid-type cells, as in cutaneous basal cell carcinoma.

(1) The solid areas resemble a conventional basaloid carcinoma, except for the presence of small mucin-containing spaces. (2) The mucinous adenocarcinoma areas contain two layers of columnar and basaloid cells. (3) Both components are neoplastic based on cell morphology, invasive properties and phenotypic profile.

These findings indicate that a basaloid variant of adenocarcinoma is also existing in the spectrum of basaloid carcinomas of the lung.

RESULTS: Six Men1+/- mice (12.8%) developed prostate cancer, including two adenocarcinomas and four in situ carcinomas, while none of the control mice developed cancerous lesions.

Using immunostaining for the androgen receptor and p63, a basal epithelial cell marker, we demonstrated that the menin-negative prostate cancer cells did not display p63 expression and that the androgen receptor was expressed but more heterogeneous in these lesions.

Furthermore, our data showed that the expression of the cyclin-dependent kinase inhibitor CDKN1B (p27), a Men1 target gene known to be inactivated during prostate cell tumorigenesis, was notably decreased in the prostate cancers that developed in the mutant mice.

CONCLUSION: Our work suggests the possible involvement of Men1 inactivation in the tumorigenesis of the prostate gland.

[Title] Role of CDK8 and beta-catenin in colorectal adenocarcinoma.

Colorectal adenocarcinoma is a major cause of morbidity and mortality.

CDK8 is a cyclin-dependent kinase (CDK) member of the mediator complex that couples transcriptional regulators to the basal transcriptional machinery, and is implicated in the transcriptional regulation of key pathways involved in colon cancers.

To determine the relationship between CDK8 and beta-catenin expressions, a population-based study was conducted for immunohistochemical staining analysis of tumor tissues, and Western blot analysis and CDK8 interference studies of colon cancer cell lines.

However, beta-catenin expression was not completely suppressed by CDK8 interference in the colon cancer cell lines HCT-116, HT-29 and SNU-C5.

Barrett's oesophagus is a metaplastic pre-malignant disorder and the only established precursor lesion for oesophageal adenocarcinoma.

These stem cells could be located in the basal layer of the squamous oesophageal epithelium and/or in the neck region of the oesophageal submucosal gland ducts; however, their exact location and identification are still matter of discussion.

Mucinous, tubular, or secretary carcinomas were frequently found in the hormone receptor positive/HER2 negative subtype, while squamous cell carcinoma, spindle cell carcinoma, and metaplastic carcinoma with bone/cartilage metaplasia were very frequently found in the TN group.

CONCLUSIONS: Although TN types are similar to basal-like breast tumor, as determined by gene profiling, their diagnosis needs verification by determination of the level of epidermal growth factor receptor or cytokeratin 5/6 expression.

The 5 leading eyelid malignant tumors were basal cell carcinoma, sebaceous gland carcinoma, lymphoma, squamous cell carcinoma and melanoma.

The mean age at diagnosis was 61 years for basal cell carcinoma and sebaceous gland carcinoma, 57 years and 52 years for squamous cell carcinoma and melanoma, respectively, and 48 years for lymphoma.

There was no significant sex predilection in basal cell carcinoma and sebaceous gland carcinoma.

Melanoma and lymphoma occurred more commonly in women, whereas squamous cell carcinoma occurred more commonly in men.

CONCLUSIONS: Basal cell carcinoma and sebaceous gland carcinoma were the most common malignant eyelid tumors, and lymphoma ranked third and had an increasing trend.

[Title] Partial atrophy on prostate needle biopsy cores: a morphologic and immunohistochemical study.

The morphologic features of the 278 cases and immunohistochemistry of 236 cases (198 with prostate cocktail and 38 with only basal cell makers) were analyzed.

Of 198 cases with a prostatic cocktail stain, 48 (24.2%) had a cancer pattern for both basal cells and AMACR (p63-, HMWCK-, and AMACR+), 14 (7.1%) had a cancer pattern for basal cells (p63-, HMWCK-, and AMACR-), 89 (44.9%) had a cancer pattern for AMACR (p63+, HMWCK+, and AMACR+), and 47 (23.7%) had a totally benign pattern (p63+, HMWCK+, and AMACR-).

Of the 198 cases using the cocktail stain, 136 (68.7%) had positive basal cell staining.

The percentage of basal cells labeled with the combination of p63/HMWCK was: <5% in 42 (21.2%) cases, 5% to 75% in 58 (29.3%) cases, and >75% in 36 (18.2%) cases.

In conclusion, partial atrophy is a benign mimicker of adenocarcinoma both as a result of its routine morphologic features and its immunohistochemical profile.

Recognition of the classic morphology of partial atrophy on routine hematoxylin and eosin-stained sections is critical to avoid misdiagnosing partial atrophy as adenocarcinoma.

[Title] Immunolabeling pattern of cytokeratin 19 expression may distinguish sebaceous tumors from basal cell carcinomas.

BACKGROUND: Distinction between sebaceous tumors and basal cell carcinomas can often pose diagnostic problems.

Our aim was to evaluate the use of CK 19 staining patterns in differentiating between sebaceous tumors and basal cell carcinomas.

METHODS: Thirty-seven cases including 5 sebaceous adenomas, 16 sebaceous epitheliomas, 6 sebaceous carcinomas and 14 basal cell carcinomas (7 being of the morpheaform type and 7 nodular basal cell carcinomas) were tested with a monoclonal mouse antibody to human CK 19.

CK 19 was found to be strongly positive in 9/14 (64%) and focally positive in 2/14 (14%) of basal cell carcinomas.

CONCLUSION: CK 19 expression can be helpful in differentiating sebaceous tumors (including sebaceous adenomas, sebaceous epitheliomas and sebaceous carcinomas) from basal cell carcinomas and may be a useful adjunct when these entities are included in the differential diagnosis.

BACKGROUND: The incidence of oesophageal adenocarcinoma is increasing rapidly in the developed world.

Therefore we have examined the activation of Akt in Barrett's oesophagus and oesophageal adenocarcinoma and the functional effects of Akt activation in vitro.

The functional effects of Akt were examined using Barrett's adenocarcinoma cells in culture.

RESULTS: In normal squamous oesophagus, erosive oesophagitis and non-dysplastic Barrett's oesophagus, phospho-Akt was limited to the basal 1/3 of the mucosa.

Image analysis confirmed that Akt activation was significantly increased in non-dysplastic Barrett's oesophagus compared to squamous epithelium and further significantly increased in high-grade dysplasia and adenocarcinoma.

In all cases of high grade dysplasia and adenocarcinoma Akt was activated in the luminal 1/3 of the epithelium.

CONCLUSION: Akt is abnormally activated in Barrett's oesophagus, high grade dysplasia and adenocarcinoma.

Akt activation promotes proliferation and inhibits apoptosis in Barrett's adenocarcinoma cells and both transient acid exposure and leptin stimulate Akt phosphorylation.

Activation of Akt in obesity and by reflux of gastric acid may be important in the pathogenesis of Barrett's adenocarcinoma.

[Title] Synergistic inhibition of pancreatic adenocarcinoma cell growth by trichostatin A and gemcitabine.

We investigated the ability of the histone deacetylase (HDAC) inhibitor trichostatin A (TSA) to interact with gemcitabine (GEM) in inducing pancreatic cancer cell death.

The combined treatment with TSA and GEM synergistically inhibited growth of four pancreatic adenocarcinoma cell lines and induced apoptosis.

The functional role of ROS in cell growth inhibition by GEM was supported by (i) a significantly reduced GEM-associated growth inhibition by the free radical scavenger N-acetyl-L-cysteine, and (ii) a positive correlation between the basal level of ROS and sensitivity to GEM in 10 pancreatic cancer cell lines.

The functional role of both Bim and 5'-nucleotidase UMPH type II in cell growth inhibition by TSA and GEM was assessed by RNA interference assays.

In vivo studies on xenografts of pancreatic adenocarcinoma cells in nude mice showed that the association of TSA and GEM reduced to 50% the tumour mass and did not cause any apparent form of toxicity, while treatments with TSA or GEM alone were ineffective.

[Title] Mutations of C-RAF are rare in human cancer because C-RAF has a low basal kinase activity compared with B-RAF.

Here we show that presumptive mutants of the closely related kinase, C-RAF, were detected in only 4 of 545 (0.7%) cancer cell lines.

The basal and B-RAF-stimulated kinase activities of a third variant are unaltered but its activation by RAS is significantly reduced, suggesting that it may act in a dominant-negative manner to modulate pathway signaling.

The fourth variant has elevated basal kinase activity and is hypersensitive to activation by RAS but does not transform mammalian cells.

We conducted this study to determine whether the basal characteristics and survival of young patients undergoing surgical resection of lung cancer differ from those of elderly patients.

The patients' medical records were reviewed with respect to age, gender, histological diagnosis, coexisting diseases, smoking history, postoperative staging, type of operation, and postoperative morbidity, mortality, and survival results.

However, the 5-year survival rates for patients who underwent surgery for non-small cell lung cancer did not differ between groups 1 and 2, at 33.3% versus 21.3%, respectively (P = 0.09).

CONCLUSIONS: The incidence of adenocarcinoma was higher in the young patients, whose prognosis was slightly better than that of the elderly patients.

To check the diagnosis of "small two- or three-gland carcinoma" we prepared new H and E sections and, when the atypical glands were no longer available, also performed immunohistochemical analyses in 1,041 cases referred to our uropathology consultation service, comparing the diagnoses supplied by the referring doctors with the final diagnoses.

In 61.6 of these cases histology confirmed the diagnosis of adenocarcinoma of the prostate; the diagnosis recorded when the basal cell marker was absent and the tumour marker P504S was strongly expressed was atypical microglandular proliferation or suspected carcinoma.

[Title] Proliferative lesions of prostate: a multivariate approach to differential diagnosis.

Prostatic needle biopsies from 142 patients were studied: 61 cases were "benign", 19 atypical small acinar proliferation, 31 high-grade prostatic intraepithelial neoplasia, and 31 adenocarcinoma.

Of these parameters, seven (glandular fusion, crystalloids, nucleolomegaly, papillary architecture, visibility of basal cell layer, areas of normal luminal cell nucleus/cytoplasm ratio and areas of high luminal cell nucleus/cytoplasm ratio) remained significant in discriminating the groups.

Multivariate analysis selected a small panel of histological features as those most helpful in the differential diagnosis of proliferative lesions in prostate biopsies.

Although mechanisms by which Barrett metaplasia evolves toward dysplasia and adenocarcinoma have been extensively studied, the process by which squamous epithelium is replaced by specialized intestinal metaplasia is poorly understood.

Areas of destroyed squamous epithelium are then progressively reepithelized by a columnar epithelium that may originate from multipotent stem cells located within the basal layer of the normal esophageal mucosa or in the ducts of submucosal glands.
