  • Histopathologic examinations of these 32 lesions revealed a second clinically unsuspected malignancy or a recurrence of a previous diagnosed carcinoma in six patients (19%) and a benign tumor or inflammatory lesion in 26 patients (81%).
  • Benign tumors and inflammatory lesions included eight colon adenomas, four Warthin's tumors, one granuloma of the lower jaw, one adenoma of the thyroid gland, one compensatory muscle activity due to vocal chord palsy, two occurrences of arthritis, three occurrences of reflux esophagitis, two occurrences of pancreatitis, two occurrences of diverticulitis, one hemorrhoidal inflammation, and one rib fracture.
  • CONCLUSION: Solitary extrapulmonary FDG accumulations in patients with newly diagnosed lung cancer should be analyzed critically for correct staging and optimal therapy, given that up to half of the lesions may represent unrelated malignancies or benign disease.

  • [Title] Predictive factors of carcinoma in 279 patients with Hürthle cell neoplasm of the thyroid gland.
  • BACKGROUND AND OBJECTIVES: Estimation of the risk of malignancy in a Hürthle cell (HC) neoplasm is important for optimum extent of thyroid surgical treatment.
  • The aim of this retrospective study was to find predictive factors of carcinoma in patients with HC neoplasm.
  • METHODS: A total of 279 patients (241 females, 38 males; median age 55 years, range 15-86 years) with HC neoplasm in whom carcinoma was only suspected and who were surgically treated at our Institute in the period 1990-2007, were included in this study.
  • RESULTS: The histopatological diagnoses were carcinoma, benign goiter and adenoma in 71 (25%), 68 (25%) and 140 (50%) patients, respectively.
  • Predictive factors for carcinoma, shown by chi-square test, were: age of patients, tumor diameter, thyroid volume and T(g) concentration.
  • CONCLUSIONS: The independent predictors of malignancy in HC neoplasm were age of patients and pre-operative T(g) concentration.

  • [Title] Differentiation of human follicular thyroid adenomas from carcinomas by gene expression profiling.
  • It is difficult to distinguish benign from malignant follicular thyroid tumors by histological or cytological examination.
  • The goal of this study was to reveal gene expression variations between benign and malignant follicular lesions of the thyroid gland.
  • We investigated gene expression profiles from 24 follicular thyroid tumors (12 carcinomas and 12 adenomas) and 13 normal thyroid tissues using high-density human cDNA arrays.
  • The identification of gene expression changes was based on signal intensity ratios of tumor versus normal thyroid parenchyma.
  • Our results demonstrate a potential use of gene expression profiling for differentiating benign from malignant follicular thyroid tumors.
  • A detailed investigation of the differentially expressed genes could give new insights into molecular pathways of malignant transformation of thyroid follicular neoplasm and may help to develop a molecular tool for the preoperative differential diagnosis.

  • [Title] Diagnosis of thyroid cancer in children: value of gray-scale and power doppler US.
  • PURPOSE: To prospectively analyze the accuracy of various diagnostic criteria for cancer in solid thyroid nodules in children on the basis of gray-scale and power Doppler ultrasonographic (US) findings.
  • One hundred three consecutive pediatric patients with solid thyroid nodules were included in the study.
  • Thirty-five patients had thyroid cancer (mean age, 14.6 years +/- 2.6 [standard deviation]; range, 10-18 years), and 68 patients had benign thyroid nodules (mean age, 14.2 years +/- 2.9; range 9-18 years).
  • Three-dimensional US was used to determine the volume of thyroid gland and thyroid nodules.
  • Multivariate logistic regression analysis was used to evaluate the accuracy of US criteria for thyroid cancer in lesions with diameter of 15 mm and smaller and lesions with diameter larger than 15 mm.
  • RESULTS: In thyroid nodules with diameter of 15 mm and smaller, the most reliable diagnostic criteria for malignancy were an irregular outline (sensitivity, 69.6%; specificity, 86.4%; P < .001), subcapsular location (sensitivity, 65.2%; specificity, 86.4%; P < .001), and increased intranodular vascularization (sensitivity, 69.6%; specificity, 87.9%; P < .01).
  • For thyroid nodules larger than 15 mm in diameter, the accuracy of US diagnosis was much lower than that for smaller nodules.
  • CONCLUSION: Study findings indicate that US is most helpful in diagnosis of thyroid malignancy in thyroid nodules with diameter of 15 mm and smaller, with detection of irregular tumor outline, subcapsular location, and increased intranodular vascularization.

  • [Title] Evaluation of peroxisome proliferator-activated receptor-gamma expression in benign and malignant thyroid pathologies.
  • Impairment of peroxisome proliferator-activated receptor-gamma (PPAR-gamma) function through a dominant negative PAX-8/PPAR-gamma fusion gene or other events resulting in wild-type PPAR-gamma downregulation has been implicated in malignant thyroid cell transformation.
  • The aim of our study was to perform a systematic evaluation of PPAR-gamma mRNA and protein expression in normal thyroid tissue as opposed to benign thyroid pathologies of different functional status and thyroid malignancy, to gain further insights into a putative physiological role of PPAR-gamma in the thyroid and to define whether PPAR-gamma could serve as a marker of thyroid cell differentiation.
  • Ten cold benign (CTN) and 10 toxic (TTN) thyroid nodules and corresponding normal thyroid tissues, 10 follicular thyroid cancers (FTC), 10 papillary thyroid cancers (PTC) and 8 Graves' disease (GD) thyroids were studied by real-time polymerase chain reaction (PCR), immunohistochemistry and reverse transcriptase (RT)-PCR (PAX-8/PPAR-gamma fusion gene).
  • When comparing benign nodular and normal thyroid tissue of the same patient no significant difference in PPAR-gamma mRNA expression was observed.
  • In contrast, PPAR-gamma mRNA expression was downregulated in 9 of 10 PTC and all GD samples, whereby at least 4 fold downregulation (compared with normal and benign nodular thyroid tissues) was observed in the latter.
  • Immunohistochemistry showed an increased, patchy PPAR-gamma nuclear staining in CTNs and TTNs and only faint staining in the corresponding normal thyroid tissues.
  • No PAX-8/PPAR-gamma rearrangements were detected in any of the 68 thyroid tissue samples.
  • In conclusion PPAR-gamma mRNA and protein expression levels are not concordant in benign thyroid nodular disease.
  • Furthermore there is no clear-cut association of PPAR-gamma mRNA expression with follicular thyroid tumorigenesis.
  • Absence of a PAX-8/PPAR-gamma fusion gene in the series of 68 thyroid samples is in agreement with the suggestion of PAX-8/PPAR-gamma rearrangement being restricted to a subset of follicular thyroid cancers.

  • BACKGROUND: A clinicopathological analysis and long-term follow up of 32 patients with Hurthle cell neoplasm (HCN) was undertaken to contrast the clinical and histological features between benign versus malignant HCN of thyroid and to examine the effect of treatment on the outcome.
  • METHODS: This is a retrospective study of 32 patients with HCN who were identified out of an archival clinical/pathological/imaging database of 3752 thyroid cancer patients seen between 1976 and June 2006.
  • All patients underwent thyroid surgery.
  • RESULTS: Seventeen patients were classified as malignant HCN (MHCN) and 15 as benign HCN (BHCN).
  • Postoperatively, three MHCN patients had no thyroid remnant on ultrasound and computed tomography of neck and undetectable serum thyroglobulin; these were considered to be in remission.
  • Fourteen other MHCN patients with postoperative thyroid remnant and/or distant metastases received 131I treatment.
  • Findings of dominant Hurthle cell cytology in a fine-needle aspiration biopsy from a thyroid nodule should prompt surgical resection of the lesion to assess malignancy.

  • [Title] Hyalinizing trabecular tumors of the thyroid gland: quadruply described but not by the discoverer.
  • Hyalinizing trabecular tumors of the thyroid have been described on 4 occasions, by Carney and colleagues in 1987, by Ward and coworkers in 1982, by Pierre Masson in 1922, and by Rahel Zipkin in 1905.
  • Unaware of the 3 earlier descriptions, Carney and colleagues described 11 circumscribed or encapsulated thyroid tumors with elongated and polygonal cells arranged in trabeculae that contained a hyaline material resembling amyloid.
  • Carney and colleagues labeled the neoplasms hyalinizing trabecular adenomas because of their microscopic appearance, absence of invasion, and benign natural history.
  • Subsequently, the nuclear features of the tumor and the molecular genetic findings led to the introduction of equivocal designations for it, hyalinizing trabecular tumor and hyalinizing trabecular neoplasm, and later to its designation as a variant of papillary carcinoma.
  • Experience has shown that most circumscribed or encapsulated follicular thyroid tumors with intratrabecular hyalin and nuclear features of papillary carcinoma behave as benign neoplasms.

  • [Title] 111In-Pentetreotide uptake in a follicular adenoma of the thyroid gland: a pitfall for 111In-Pentetreotide scintigraphy.
  • 111In-pentetreotide scintigraphy showed discrete uptake of the radiotracer in the head of the pancreas and focal uptake in the right upper thyroid lobe.
  • Normal thyroid tissue and thyroid disorders, such as cancers, Hashimoto's thyroiditis, and adenomas often show increased uptake of 111In-pentetreotide resulting in a possible false positive interpretation in patients with neuroendocrine tumor.
  • Adding a 48h planar image might contribute to the differential diagnosis between benign or malignant lesions, as in the present case where the uptake decreased in an adenoma after 48 hours.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Hyalinizing trabecular tumors of the thyroid gland are almost all benign.
  • In 1987, Carney et al reported 11 thyroid tumors with the following features: circumscription or encapsulation, trabecular architecture with intratrabecular hyalin and colloid, polygonal and spindle cells, nuclei with frequent grooves and cytoplasmic inclusions, occasional psammoma bodies, and a low mitotic rate.
  • Subsequently, the nuclear features of the neoplasm led to the introduction of 2 modified titles for it, hyalinizing trabecular tumor and hyalinizing trabecular neoplasm.
  • Later, discovery of RET/PTC mutations in the tumor resulted in it being designated as a type of papillary thyroid carcinoma.
  • We conclude that the overwhelming majority of hyalinizing trabecular tumors of the thyroid behave as benign neoplasms and that, at this time, hyalinizing trabecular adenoma is the most appropriate title for them.

  • [Title] Diagnostic value of a cytomorphological subclassification of follicular patterned thyroid lesions: a study of 927 consecutive cases with histological correlation.
  • BACKGROUND: Fine-needle aspiration cytology (FNAC) has proved to be an effective diagnostic tool in patients with thyroid nodules.
  • To date, however, among lesions showing a follicular pattern, FNAC is still unable to differentiate between benign and malignant ones.
  • METHODS: We report a cohort of 927 consecutive cases who underwent thyroid surgery in our hospital between 2000 and 2008.
  • All the cytologic specimens were divided into five categories (Thy 1: inadequate material, Thy 2: benign, Thy 3: indeterminate, Thy 4: suspicious for malignancy, Thy 5: malignant).
  • Thy3 specimens were further divided into three subcategories (Thy 3a, or "follicular lesions of indeterminate significance": scant colloid, microfollicular pattern, or small clusters of thyrocytes with round nuclei usually without, but sometimes with, minimal cellular pleomorphism; Thy 3b, or "follicular neoplasm": absence of colloid, small clusters, or microfollicles of medium-large sized cell populations arranged in cohesive groups with nuclear overlapping, crowding, and pleomorphisms; and Thy 3c or "Hurthle-cell neoplasm": scant colloid, sheets or clusters of oxyphilic cells).
  • This subclassification could improve clinical management of thyroid nodules, helping to better select patients for surgery or follow up.

  • Pituitary adenomas are common benign neoplasms, accounting for approximately 15% of intracranial tumors.
  • The progress in the studies concerning pituitary tumorigenesis is rather slow and, due to several limitations, including the anatomic inaccessibility of human pituitary gland, the lack of functional human cell lines in culture and the discrepancies between human and animal pituitary oncogenesis (in rodents pituitary hyperplasia is a prerequisite for adenoma development).
  • In humans, the majority of pituitary tumors are monoclonal in origin and derived from single mutated pituicyte, rarely hyperplasia is a prerequisite for adenoma formation.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] HMGA2 gene expression analysis performed on cytologic smears to distinguish benign from malignant thyroid nodules.
  • BACKGROUND: Up to 80% of thyroid nodules with an indeterminate diagnosis on fine-needle aspiration (FNA) (eg, "suspicious for follicular neoplasm") prove to be benign at the time of surgical resection.
  • Ancillary tests in current use are limited in their ability to improve the preoperative detection of malignant follicular thyroid nodules.
  • Studies using paraffin-embedded tissue have indicated that high mobility group AT-hook 2 (HMGA2) overexpression is present in a high percentage of malignant thyroid neoplasms but not in benign thyroid neoplasms.
  • In the current study, the ability of HMGA2 overexpression analysis to preoperatively distinguish benign from malignant thyroid nodules by reverse transcriptase-polymerase chain reaction (RT-PCR) on suspicious cytologic smears was evaluated.
  • METHODS: Patients who underwent thyroid FNA and subsequent thyroid resection from 2001 through 2007 were identified.
  • With an HMGA2 overexpression change of 5.9-fold or greater compared with a thyroid tumor cell line as a positive cutoff, the test was found to have the following overall performance for detecting malignant nodules: sensitivity of 71%, specificity of 97%, positive predictive value of 94%, and negative predictive value of 84%.
  • CONCLUSIONS: HMGA2 mRNA expression analysis can be performed on cytologic smears and demonstrates a high specificity and positive predictive value and relatively high sensitivity and negative predictive value for detecting malignancy in "suspicious" thyroid aspirate specimens.

  • [Title] [The frequency of malignant disease in cytological group of suspected cancer (ultrasound-guided fine-needle aspiration biopsy of nonpalpable thyroid nodules)].
  • BACKGROUND: Fine-needle aspiration biopsy is the most important procedure for differentiating benign thyroid nodules from malignant ones.
  • Traditionally, findings of fine-needle aspiration biopsy are divided into four categories: nondiagnostic, benign lesions, suspected cancer, and malignant lesions.
  • OBJECTIVE: The purpose of this study was to establish the value of ultrasound-guided fine-needle aspiration biopsy in the diagnosis of nonpalpable thyroid cancer and to assess the frequency of malignant disease in the group of suspected cancer.
  • PATIENTS AND METHODS: A total of 184 patients with nonpalpable thyroid nodules (less than 1.5 cm in diameter) were examined by means of ultrasound-guided fine-needle aspiration biopsy.
  • RESULTS. During 1997-2002, 204 ultrasound-guided fine-needle aspiration biopsies of thyroid nodules were performed; findings were nondiagnostic in 5.9% of cases.
  • In 59.8% of cases, cytological examination revealed benign lesions; in 11.8%, suspected cancer; and in 22.5%, malignant lesions.
  • In 45 cases, cytological diagnosis of malignant or suspected thyroid cancer was confirmed by histological examination after surgery.
  • CONCLUSION: We conclude that ultrasound-guided fine-needle aspiration biopsy has a high accuracy in the diagnostic evaluation of nonpalpable thyroid nodule with cytological features of malignancy.
  • However, fine-needle aspiration biopsy is not effective diagnostic method for differentiating benign thyroid nodules from malignant ones in follicular neoplasm group.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • As most cases are caused by parathyroid adenoma, there is a movement toward preoperative localization of the abnormal gland by ultrasound and/or Tc(99)-sestamibi scan and minimally invasive parathyroidectomy.
  • Nonpalpable thyroid nodules are common and cannot be differentiated from parathyroid lesions by imaging alone.
  • Between January 1, 2007 and December 31, 2008, seven patients with PHPT or other parathyroid lesions with one or more sonographically-visible thyroid masses underwent cytopathologist-performed UG-FNA with immediate cytological evaluation (ICE).
  • Three parathyroid adenomas, two benign colloid nodules, one papillary carcinoma, three parathyroid cysts, and one thyroid cyst were diagnosed.
  • The nodules in three patients with parathyroid adenomas were identified as follicular lesion/neoplasm on ICE.
  • Two of these patients had a separate benign colloid nodule and one had a thyroid cyst diagnosed by UG-FNA.
  • The PHPT patient with papillary carcinoma on UG-FNA had the malignancy confirmed at surgery and a sonographically occult parathyroid adenoma.
  • The three patients with thyroid cysts identified by radiology were suspected of being parathyroid cysts on the basis of real-time sonographic features at the biopsy table.
  • Cytopathologist-performed UG-FNA can distinguish between parathyroid and thyroid nodules in patients with suspected parathyroid lesions.

  • Galectin-3 is a 31kD beta-galactoside binding lectin, which is known to be expressed in various neoplasms including thyroid tumors.
  • This study was conducted to study the role of galectin-3 in differentiating benign from malignant thyroid nodules onfine needle aspirates (FNAC).
  • The cytology diagnosis of these cases was: papillary carcinoma (25), follicular neoplasm (16), adenomatous goiter (20), hyperplastic nodule (5), medullary carcinoma (5) and anaplastic carcinoma (1).
  • Galectin-3 positivity was seen in 80% of papillary carcinomas, 37.5% offollicular neoplasms and in 60% of benign nodules.
  • Three of thefollicular neoplasms that were diagnosed on histology as carcinoma were positive on cytology and one case offollicular adenoma was also positive.
  • However, since it is also expressed in a variety of benign lesions, its role as a pre-surgical markerfor differentiating benignfrom malignant thyroid nodules is limited.

  • [Title] NDRG1 protein overexpression in malignant thyroid neoplasms.
  • OBJECTIVES: The aim of this study was to examine the expression of the N-myc downstream-regulated gene 1 protein in benign and malignant lesions of the thyroid gland by immunohistochemistry.
  • Increased N-myc downstream-regulated gene 1 expression has been detected in various types of tumors, but the role of N-myc downstream-regulated gene 1 expression in thyroid lesions remains to be determined.
  • METHODS: A tissue microarray paraffin block containing 265 tissue fragments corresponding to normal thyroid, nodular goiter, follicular adenoma, papillary thyroid carcinoma (classical pattern and follicular variant), follicular carcinoma, and metastases of papillary and follicular thyroid carcinomas were analyzed by immunohistochemistry using a polyclonal anti- N-myc downstream-regulated gene 1 antibody.
  • RESULTS: The immunohistochemical expression of N-myc downstream-regulated gene 1 was higher in carcinomas compared to normal thyroid glands and nodular goiters, with higher expression in classical papillary thyroid carcinomas and metastases of thyroid carcinomas (P < 0.001).
  • A combined analysis showed higher immunohistochemical expression of NDRG1 in malignant lesions (classical pattern and follicular variant of papillary thyroid carcinomas, follicular carcinomas, and metastases of thyroid carcinomas) compared to benign thyroid lesions (goiter and follicular adenomas) (P = 0.043).
  • In thyroid carcinomas, N-myc downstream-regulated gene 1 expression was significantly correlated with a more advanced TNM stage (P = 0.007) and age, metastasis, tumor extent, and size (AMES) high-risk group (P = 0.012).
  • CONCLUSIONS: Thyroid carcinomas showed increased immunohistochemical N-myc downstream-regulated gene 1 expression compared to normal and benign thyroid lesions and is correlated with more advanced tumor stages.

  • [Title] Hurthle cell neoplasms of the thyroid: sonographic appearance and histologic characteristics.
  • OBJECTIVE: The purpose of this study was to determine the sonographic features of Hürthle cell neoplasms (HCNs) of the thyroid.
  • Two tumors (13%) were predominantly hypoechoic with isoechoic areas to thyroid parenchyma.
  • Two (13%) neoplasms were isoechoic to thyroid parenchyma.
  • One neoplasm showed only peripheral blood flow.
  • Twelve HCNs were benign, and 3 were malignant on pathologic examination.
  • Pathologic criteria differentiating benign and malignant HCNs (absence or presence of a capsular breach, vascular or extrathyroidal tissue invasion, nodal involvement, and distant metastasis) are beyond the resolution of sonography and fine-needle aspiration biopsy and require removal of the entire lesion.

  • BACKGROUND: Hürthle cell neoplasms (HCNs) are rare tumors of the thyroid gland.
  • The definitive treatment for Hürthle cell carcinoma (HCC) is total thyroidectomy, while thyroid lobectomy is adequate for Hürthle cell adenoma (HCA).
  • METHODS: Between May 1994 and January 2007, 1,199 patients underwent thyroid surgery at an academic medical center.
  • Medical records of 55 consecutive patients who underwent thyroid resections for the preoperative diagnosis of HCN were reviewed.
  • Patients with carcinoma also had significantly larger thyroid nodules (4.5 +/- 0.7 cm versus 2.5 +/- 0.2 cm, P < 0.001).
  • All HCNs less than 2 cm in diameter were benign.

  • [Title] [Usefulness of detecting cancer procoagulant activity and thyrotropic hormone concentration in the differentiation of tumor-like changes in the thyroid].
  • Epidemiological studies have shown the increased incidence of malignant cancer of the thyroid gland observed in the last decade.
  • This increase is connected with the elevated number of benign tumor-like/tuberous changes in the thyroid gland.
  • The aim of our study was to evaluate the usefulness of detecting cancer procoagulant activity (CP) and thyrotropic hormone concentration (TSH) in the differentiation of tumor-like changes in the thyroid gland.
  • The study included 15 patients (12 women and 3 men) with adenoma glandulae thyreoideae or nodular changes in the character of struma nodosa hyperplastica and 12 patients (11 women and 1 man) with carcinoma glandulae thyreoideae.
  • The results of our study indicate that the determination of CP activity can be used in the differential diagnosis of tumor-like changes of the thyroid gland.

  • [Title] Intraoperative frozen-section analysis for thyroid nodules: a step toward clarity or confusion?
  • OBJECTIVES: To determine accuracy and intertest agreement of preoperative fine-needle aspiration cytology (FNAC) and intraoperative frozen-section analysis (FS) findings in thyroid surgery, and to assess the influence of intraoperative FS findings on decision making and the utility of FS in thyroid surgery.
  • PATIENTS: Two-hundred fifteen patients who underwent primary thyroid surgery.
  • In case of malignant FNAC findings, the FS result did not influence treatment decisions; in case of a malignant FS result on the background of a benign, indeterminate, or nondiagnostic FNAC finding, the FS result influenced treatment decisions in 88% of cases.
  • CONCLUSIONS: Intraoperative FS did not give additional information in cases where a malignant neoplasm was predicted by the FNAC finding.

  • [Title] Clinical outcomes for "suspicious" category in thyroid fine-needle aspiration biopsy: Patient's sex and nodule size are possible predictors of malignancy.
  • CONTEXT: Fine-needle aspiration (FNA) is recommended as an initial screening tool for the diagnosis of thyroid nodules.
  • Approximately 10% of thyroid FNA diagnoses are "suspicious for neoplasm," warranting surgical resection.
  • OBJECTIVES: To examine the role of a patient's age, sex, size of nodule, and morphologic features as possible predictors of malignancy in patients with cytologic diagnosis of "suspicious for neoplasm."
  • DESIGN: Cytopathology slides and reports of 402 consecutive thyroid FNAs from 2000-2005 interpreted as "suspicious" were reviewed.
  • RESULTS: Of the 108 cases suspicious for follicular neoplasm on cytologic evaluation, histologic follow-up showed malignancy in 26 (24%).
  • Of the 37 cases suspicious for Hürthle cell neoplasm, 15 (41%) had malignancy.
  • Among cases with cytologic diagnoses of "suspicious for follicular or Hürthle cell neoplasm," the rate of malignancy in female patients was 22% as compared to 43% in male patients (P = .02).
  • No statistically significant difference was noted between the age of the patient and the rate of benign versus malignant diagnosis.
  • CONCLUSIONS: Malignant tumors were more frequent in male patients with a cytologic diagnosis of "suspicious for follicular or Hürthle cell neoplasm" than in female patients.

  • [Title] Burkitt-like lymphoma infiltrating a hyperfunctioning thyroid adenoma and presenting as a hot nodule.
  • BACKGROUND: Most solitary hyperfunctiong regions on thyroid scan consist of benign tissue.
  • SUMMARY: A 56-year-old man was referred to our Endocrine Unit in May 2009 due to the incidental discovery of a large left thyroid lobe nodule by a computed tomography study.
  • He was clinically and biochemically thyrotoxic with no evidence of humoral thyroid autoimmunity.
  • The nodule had a dyshomogenous appearance at neck ultrasonography, with multiple hypoechogenic areas and calcifications. (99m)-Technetium thyroid scintiscan revealed a hot nodule with suppression of the contralateral lobe.
  • Fine-needle aspiration cytology indicated the presence of neoplastic cells not of thyroid origin.
  • Histological analysis of the surgical specimen led to a diagnosis of Burkitt-like large B-cell lymphoma harbored within a thyroid adenoma.
  • After further staging, the final diagnosis was stage IV E Burkitt-like lymphoma with the involvement of the bone and the thyroid.
  • This is the first description of an aggressive Burkitt-like lymphoma that infiltrated an hyperfunctioning thyroid adenoma, thus presenting as a hot nodule at thyroid scintiscan.
  • In our patient there was no humoral or histological evidence of thyroid autoimmunity, thus suggesting a metastatic seeding of the lymphoma within the hyperfunctioning thyroid nodule.
  • CONCLUSIONS: Involvement of the thyroid gland by Burkitt-like lymphoma is extremely rare as is close localization of malignancy and a hyperfunctioning thyroid nodule.
