  • [Transliterated title] Sarcome d'Ewing Osseux et Extra Osseux : Etude anatomo-clinique de 29 cas.
  • BACKGROUND: Ewing's sarcoma (ES) is a rare tumour accounting for 10% of primary malignant bone tumours in children and 3% of all childhood malignancies.
  • ES belongs to a group of small round cell tumours.
  • AIM: In this review, we will describe the main clinicopathological features of this rare tumour and discuss its prognosis.
  • RESULTS: 12 patients were male and 17 were female (ratio: 0,8) with a median age of 16 years.
  • The medium size of the tumor was 10,6 cm (range:3-25cm).
  • 27,5% of patients presented with metastatic disease at time of diagnosis.
  • Microscopically, tumour tissue was composed of round, small, blue cells with fine granular chromatin.
  • Tumour cells strongly coexpressed CD99 and vimentin (100%).
  • Systemic treatment consisted of adjuvant chemotherapy (84,2%).
  • Local control was based on and surgery (57,9%) or radiation therapy (36,8%).
  • A good response to chemotherapy was obtained in 37.5%; 13,7% of patients were alive without disease (medium follow up: 169 mois); 34,5% of patients developed metastases (medium follow up : 23 months) and 10,3% developed recurrences (medium follow up :13 months).
  • CONCLUSION: Our study emphasizes two points : the great size of the tumor and the frequent location in flat bone which may explain the poor prognosis of Ewing sarcoma in our series despite the multidisciplinary treatment.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Malignant granular cell tumor: a clinicopathologic analysis of 10 cases with review of literature].
  • OBJECTIVE: To investigate the clinicopathologic features of malignant granular cell tumor (MGCT) and evaluate the histologic criteria for diagnosis of malignancy.
  • Electron microscopy was carried out in 3 cases with available fresh or formalin-fixed tissues.
  • The main presenting symptom was a painless nodule or mass located in the subcutis or deep soft tissue.
  • One case had peripheral nerve symptoms.
  • The tumor size ranged from 2 to 11 cm (mean size = 4.8 cm).
  • Microscopically, the tumor was composed of nests or sheets of polygonal cells which possessed abundant eosinophilic granular cytoplasm and closely resembled its benign counterpart.
  • After careful assessment, 9 cases exhibited at least 3 of the following suspicious features: enlarged vesicular nuclei with prominent nucleoli, nuclear pleomorphism, high nuclear-to-cytoplasmic ratio, spindling of tumor cells, appreciable mitotic activity, and tumor necrosis.
  • In addition, a hitherto undescribed feature characterized by multinucleated tumor cells was observed in 1 case.
  • The remaining case demonstrated benign-appearing features but behaved in a malignant fashion.
  • Follow-up information available in 7 patients revealed local recurrence in 5, metastasis in 4 and tumor-related deaths in 2 patients.
  • In exceptional circumstances, however, the diagnosis relies on clinicopathologic correlation.
  • Wide local excision with regional lymph node dissection remains the mainstay of treatment.
  • Chemotherapy and radiotherapy however have not been shown to significantly improve the clinical course of the disease.
  • The morphologic spectrum of MGCT also includes a rare multinucleated variant.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Malignant bronchial Abrikossoff's tumor and small cell lung cancer: a case report and review.
  • Bronchoscopy showed an endobronchial mass; washing cytology was negative and histology findings suggested diagnosis of granular cell tumor (GCT), also called Abrikossoff's tumor.
  • After 3 weeks a new washing cytology test revealed the presence of small cell lung cancer (SCLC).
  • A CT-scan and chest radiography showed a 30% increase in the maximum diameter of the lesion, clinically defining the primary neoplasm as malignant.
  • The patient was referred to our institution and started chemotherapy with cisplatin and etoposide.
  • After 6 cycles of treatment, the CT scan showed complete, disappearance of the neoplasm and bronchoscopy examination showed no endobronchial lesion, defining the mucosal surface as normal.
  • We have reviewed and summarized the international literature with regard to bronchial localization of malignant granular cell tumor and its association with SCLC, therefore concluding that our case is the first malignant endobronchial GCT linked to SCLC.

  • [Title] [An advanced aged case of intrapulmonary metastasis of non-small cell lung cancer successfully controlled with S-1 capsule therapy alone for an extended period].
  • About 7 months after surgery for a non-small cell lung cancer StageIII B, granular shadows were noted on his bilateral lungs on CT; and the level of CA 19-9 , a tumor marker, had increased.
  • These findings led to a diagnosis of intrapulmonary tumor metastasis.
  • Treatment with a platinum-based antineoplastic agent was recommended,but the patient refused it because of his age.
  • Because the tumor appeared to increase in size, treatment was initiated using S-1 capsules (hereafter abbreviated to S-1) alone.
  • Each course consisted of S-1 at a dosage of 100 mg/body/day, twice daily for 21 days, followed by 14 days of drug withdrawal.
  • After the completion of one course, the level of the tumor marker was reduced to normal.
  • Malignant phenomenon exceeding grade 3 was no longer recognized,and it was possible to deliver the scheduled dosage of S-1 throughout the entire series of courses.
  • It has been about 18 months after the S-1 single therapy was started.
  • This therapy is still being continued.

  • The tumor shrunk from 6.5 cm to 2.5 cm after the treatment.
  • The residual tumor in the surgical specimen measured 1.5 cm with eight positive out of 24 axillary lymph nodes.
  • The tumor showed typical chemotherapy changes and a massive proliferation of histiocytes that mimicked a neoplasm.
  • A nodular proliferation of the same cells in one axillary node raised the impression of a second malignant tumor in the breast spreading to the node.
  • These findings ruled out histiocytoid carcinoma, granular cell tumor, and Erdheim-Chester disease.

  • [Title] Clear cell adenocarcinoma of colorectum: a case report and review of the literature.
  • Primary clear cell adenocarcinoma of the colorectum is a rare neoplasm, which differs from ordinary carcinomas of the colorectum in morphological features, but shares some traits of clear cell carcinoma of other organs.
  • The tumor is usually composed of polygonal or oval cells with abundant granular and clear cytoplasm.
  • We report the first case of clear cell adenocarcinoma of the colorectum in China and review the related published cases.
  • The tumor was located in descending colon of a 37-year-old man, and was rich in glycogen but poor in mucin.
  • By immunoperoxidase and histochemical staining, we clarified the clinicopathological characteristics, diagnosis and differential diagnoses, and pursued its potential pathogenesis.
  • In our case, necrosis, high mitotic activity and lymph node metastasis may suggest a highly malignant tumor and an advanced pathological stage.
  • Nevertheless, the patient has survived for one year with the help of operation and postoperative adjuvant chemotherapy.
  • Regardless of the stage and differentiation, surgical therapy and proper adjuvant chemotherapy are effective means to treat the clear cell adenocarcinoma of the colorectum.

  • OBJECTIVE: To study the clinicopathologic features, diagnostic criteria, differential diagnosis and treatment options of ovarian steroid cell tumor, not otherwise specified (NOS).
  • METHODS: Light microscopy and immunohistochemical study was carried out in 8 cases of ovarian steroid cell tumor, NOS.
  • RESULTS: The 7 cases of benign ovarian steroid cell tumor, NOS were composed mainly of polygonal cells with granular eosinophilic cytoplasm and larger cells with vacuolated cytoplasm.
  • They resembled the architecture of normal adrenal gland, with formation of cell nests and trabeculae.
  • The single case of malignant ovarian steroid cell tumor had evidence of significant cellular pleomorphism, haemorrhage and coagulative tumor necrosis.
  • Immunohistochemical study showed that the tumor cells expressed calretinin and alpha-inhibin.
  • Differential diagnosis included oxyphilic granulosa cell tumor, thecoma, Sertoli cell tumor and clear cell carcinoma.
  • The treatment options of benign ovarian steroid cell tumor, NOS was local excision or ipsilateral salpingo-oophorectomy, while the malignant counterpart should be treated with a combination of surgery and chemotherapy, including administration of GnRH agonist.
  • CONCLUSIONS: Ovarian steroid cell tumor, NOS, is the most common type of ovarian steroid cell tumors.
  • Most of which are associated with a benign clinical outcome.
  • Immunohistochemistry is an important adjunct for diagnosis.
  • The treatment options of ovarian steroid cell tumor, NOS depend on its malignant potential.

  • [Title] Recurrent granular cell tumor: how to treat.
  • Granular cell tumor is an uncommon lesion usually located in the head and neck region (50%) with a female sex predominance.
  • It is believed to be of primitive neuroectodermal origin.
  • Granular cell tumor has a peculiar clinical behavior ranging from clearly benign, locally aggressive, or manifestly malignant.
  • Treatment is surgical excision, but recurrences are possible.
  • In this article, we present a case of recurrent benign granular cell tumor with the discussion of the treatment modalities.
  • The patient was a 16-year-old girl with a 3-year history of a painless mass on the right side of her neck.
  • The mass was excised two times at different centers and diagnosed as granular cell tumor after the pathologic examination.
  • The time interval between the operations and recurrences was approximately 1 year.
  • The lesion was excised under local anesthesia with a 1-cm safe margin and the resulting defect was closed primarily after undermining of the wound edges.
  • Postoperatively, the wound began to heal with a hypertrophic scar and immediate precautions were taken.
  • Topical steroid treatment and silicone blocks were applied.

  • [Title] New developments in anti-tumor efficacy and malignant transformation of human natural killer cells.
  • For decades, the driving force behind many immunologic studies has been the hope of augmenting anti-cancer therapy through targeted immune-based strategies.
  • The question remains: can immune cells be successfully manipulated to augment chemotherapy and aid in the elimination of malignancy?
  • Such efforts have included work with natural killer (NK) cells, large granular lymphocytes that contribute to the early innate immune response by nonspecifically killing pathogens, virus-infected cells, and tumor cells, and by producing important early immunoregulatory cytokines such as interferon gamma (IFN-gamma).
  • These qualities have made NK cells attractive candidates for therapy aimed at boosting host immunity against tumor cells and infectious pathogens.
  • Recent advances in our understanding of how NK cells select targets for killing have improved our ability to design and test more effective immune-targeted therapies.
  • NK leukemias and lymphomas, while rare, represent a significant challenge to the patients and physicians coping with them, as most lack effective treatment strategies.
  • This brief review will summarize current directions in NK cell immune therapy and give an update on the classification and treatment of NK malignancies.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Pulmonary metastases from Abrikossoff's tumour. Transformation capability of a benign granular cell tumour].
  • INTRODUCTION: Abrikossoff's tumour or granular cell tumour is usually benign involving multiple anatomical sites, most frequently the head, neck and airways.
  • Occasional observations of aggressive malignant tumours have been reported, associated with a poor prognosis.
  • CASE REPORT: We report the case of a mammary Abrikossoff's tumour, initially considered benign and treated solely by local surgery.
  • Seven years later the tumour was responsible for the development of sub-cutaneous and pulmonary metastases.
  • Local surgery was again the only treatment given in the absence of evidence for the effectiveness of alternative treatment with chemotherapy or radiotherapy.
  • CONCLUSION: This original observation reports the case of a benign granular cell tumour that underwent malignant transformation after an interval of 7 years as indicated by the clinical progress and the cellular proliferation index Ki-67.

  • [Title] Metabotropic glutamate receptors: new targets for the control of tumor growth?
  • Cancer stem cells are currently a target for the treatment of malignant tumors.
  • Transformed neural stem-progenitor cells of the brain subventricular zone and the external granular layer of the cerebellum are the putative cells of origin of malignant gliomas and medulloblastomas, which are the most frequent malignant brain tumors in adults and children, respectively.
  • At least two receptor subtypes - mGlu(3) and mGlu(4) receptors - control the proliferation of brain tumor cells, whereas mGlu(1) receptors have been implicated in the development of melanomas.
  • We believe that individual mGlu receptor subtypes represent new potential targets for the treatment of several malignant tumors, including brain tumors.

  • A 32-year-old man had noticed a tumor in his left buttock 5 years earlier but had not sought treatment because the tumor had been painless.
  • He visited our hospital because the tumor had gradually increased in size.
  • The resected tumor was 12 × 8 × 6 cm in size and had a delineated margin.
  • The histological diagnosis was sclerosing epithelioid fibrosarcoma with a negative surgical margin.
  • Multiple tumor nodules were recognized in both lungs 9 months after the initial surgery, and an excisional biopsy was performed.
  • A histological examination revealed a metastasis of sclerosing epithelioid fibrosarcoma, and chemotherapy was initiated.
  • Pleural disseminations were detected 4 years after the chemotherapy, and the pleural effusion was sampled for cytological examination.
  • The cytological examination revealed several medium-sized cell clusters with moderate overcrowding and an epithelioid cell arrangement; numerous histiocytes and lymphocytes and a small amount of mesothelial cells were observed in the background.
  • The nuclei were pleomorphic with oval, spindle, or cleaved shapes and occasional multinucleation; they were located eccentrically in the cytoplasm and exhibited uniformly fine granular chromatin, a thin nuclear membrane, and several small nucleoli.
  • The above cytological features, coupled with the clinical findings, enabled a diagnosis of sclerosing epithelioid fibrosarcoma.

  • [Title] Photodynamic therapy of C6-implanted glioma cells in the rat brain employing second-generation photosensitizer talaporfin sodium.
  • OBJECT: The usefulness of photodynamic therapy (PDT) as a local therapy for malignant glioma was evaluated by investigating histological changes in a rat C6 glioma model treated with a combination of talaporfin sodium, a water-soluble photosensitizer derived from chlorophyll and exposure to a diode laser.
  • The brain was removed 1, 3 or 6h after laser irradiation for histological examination of tumor-affected brain tissue and surrounding normal brain tissue.
  • RESULTS: In addition to the tumor mass, tumor cells invading surrounding edematous brain tissue were seen in untreated rats, ranging from the brain surface to a depth of 2mm.
  • One hour after PDT, coagulation necrosis as well as disappearance of indication of cell viability such as disappearance of tumor cell processes and foamy changes of cytoplasm were noted in the tumor tissue at a depth of 0.5mm, accompanied by reduction of cytoplasmic glial fibrillary acidic protein (GFAP) expression and appearance of granular M30 cytodeath positivity.
  • Three hours later, the cytoplasm of the residual tumor cells showed disappearance of GFAP expression and increased expression of M30 cytodeath.
  • Six hours later, the foamy cytoplasm of swollen tumor cells demonstrated strong positivity for M30 cytodeath.

  • [Title] Neurofibromatosis type 1-associated unusual pleomorphic astrocytoma displaying continual malignant progression.
  • Patients with neurofibromatosis type 1 (NF1) often have gliomas as a complication, most of which are benign pilocytic astrocytomas which have arisen in optic pathways.
  • In the present case, a 17-year-old girl (at death) with stigmata of NF1, initially had a bulky tumor mass in the left thalamus, developing into the lateral ventricle, at 13 years of age.
  • Partially resected tissue samples showed pleomorphic astrocytoma with abundant xanthoma cells and degenerative structures such as Rosenthal fibers (RF) and eosinophilic granular bodies.
  • The residual tumor was subtotally resected 6 months later, and the tumor histology was essentially similar as before, accompanying the regenerative structures; this was believed to be a good prognostic indicator.
  • After a 2-year, disease-free interval, multiple tumor relapse occurred in June 1997.
  • Partially resected tumor tissues were composed of monotonous small anaplastic cells with prominent proliferative activity.
  • Surprisingly, the tumor cells had retained eosinophilic granules within the cell bodies.
  • Postoperative chemotherapy with procarbazine, MCNU and vincristine (PCV) suppressed the residual tumor dramatically, but the regrowing tumor finally became uncontrollable, leading to the patient's death.
  • TP53 mutation was not detected, while p27 immunopositivity was constantly high during malignant progression, suggesting acquisition of proliferative activity to overcome p53 and p27 inhibitory functions.
  • A review of previously published reports failed to reveal any cases of this type.
