Sclerosing mucoepidermoid carcinoma with eosinophilia is a rare thyroid neoplasm of uncertain pathogenesis that resembles salivary gland mucoepidermoid carcinoma. This multi-institutional study characterizes the clinicopathologic and molecular features of this tumor by utilizing next-generation sequencing to assess common mutations and gene fusions involved in thyroid carcinogenesis as well as fluorescence in-situ hybridization for MAML2 translocations typical of salivary gland mucoepidermoid carcinoma. Nine cases (6 females and 3 males, mean age: 59 years, range 30-77 years) were identified...

OBJECTIVES: In clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (DTC) patients with high serum thyroglobulin (Tg) and negative (131)I whole-body scan (WBS) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. The purpose of this study was to evaluate the value of (18)F-FDG PET/CT scan in DTC patients with high serum Tg level and negative (131)I WBS. METHODS: 69 post-surgical DTC patients with high serum Tg level and negative post ablation (131)I WBS were enrolled in this study...

BACKGROUND: Carcinomas of the thyroid follicular epithelium are the most common cancers of the endocrine system. In the diagnosis of thyroid nodules and tumors, the gold standard is histological evaluation. In cases which have morphological overlap, immunohistochemistry is needed for differential diagnosis. The purpose of this study is to investigate the expressions of CD56, HBME-1, cytokeratin 19 (CK19) antibodies in papillary thyroid carcinoma (PTC) and thyroid nodular lesions and their contributions to differential diagnosis...

The risk of cancer is relatively higher in Graves' patients presenting simultaneously with thyroid nodules. Radioiodine (RAI) therapy recommended in high-risk differentiated thyroid carcinoma may be associated with worsening of a pre-existing Graves' orbitopathy (GO) or developing a new onset. The impact of RAI therapy in patients with differentiated thyroid cancer on the course of a pre-exisiting GO has not been specifically investigated.The aim of this study is to assess the influence of RAI treatment administered for differentiated thyroid cancer on the course of a pre-existing GO...

Medullary carcinoma of the thyroid (MTC) commonly spreads through the lymphatics to distant sites such as lung, liver and bone. Spread to the breast is rare. We report a case of metastatic MTC which progressed to develop nodal metastases to cer-vical and mediastinal regions, visceral metastases to the liver, lung and ultimately to bilateral breasts. Clinically it is important to distinguish metastatic breast lesions from primary breast cancer as each is managed differently. Both cytological and radio-logical investigations were done followed by excision biopsy...

Renal cell carcinoma (RCC) has a high metastatic potential, and most commonly metastasizes via the bloodstream, although lymphatic metastases also occur. RCC is well-known for its propensity to metastasize to unusual sites, and late metastasis, even after a number of years, is common. The occurrence of RCC metastasis to the head and neck region is uncommon, and occurs primarily in the thyroid gland and in patients with widespread dissemination. Involvement of the parathyroid gland in metastatic carcinoma is extremely rare...

REVIEW
Elisabeth Joye Petr, Tobias Else
Endocrine tumor syndromes, eg, multiple endocrine neoplasia types 1 and 2, were among the first recognized hereditary predisposition syndromes to tumor development. Over time, the number of endocrine tumor syndromes has significantly expanded, eg, with the recent inclusion of hereditary paraganglioma syndromes. Associations of non-endocrine tumors with hereditary endocrine tumor syndromes and endocrine tumors with non-classical endocrine tumor syndromes have emerged. These findings have certainly expanded the scope of care, necessitating a multidisciplinary approach by a team of medical professionals and researchers, integrating shared patient decision-making at every step of surveillance, diagnosis, and treatment...

Cystadenoma is a rare benign salivary gland epithelial tumor that is characterized by intraluminal papillary projection. Majority of the tumors are located in minor salivary glands and usually occur in palatal and buccal mucosa, but rarely found in retromolar area. Clinically it is difficult to differentiate it from other minor salivary gland tumors, and diagnosis is chiefly based on characteristic clinical features and immunohistochemistry. We present a case of Cystadenoma arising from the minor salivary gland in retromolar area of a 44 year old female patient with a special emphasis on the immunohistochemistry to rule out the metastatic follicular carcinoma of thyroid...

AIMS: Solid variant of papillary thyroid carcinoma (SVPTC) is characterized by a solid component (SC) involving more than 50% of the tumor with the preservation of the classical cytological features of papillary thyroid carcinoma (PTC). However, clinical significance of SC in PTC has rarely been examined. Herein, we retrospectively investigated the clinicopathological features of PTC with various degree (10 to 85%) of SC (PTCSC). METHODS: Patients with PTCSC (n=27) were stratified into SC-major (SC >50% of the tumor) and SC-minor (SC <49%) groups...

We describe herein histologic, immunohistochemical, and molecular findings and clinical manifestations of a rare case of an extremely well differentiated papillary thyroid carcinoma (EWD-PTC). Similarly, it is also difficult to diagnose follicular variant papillary thyroid carcinoma (FVPTC), whose diagnosis is still met with controversy. A recently reported entity of well-differentiated tumor of uncertain malignant potential (WDT-UMP) is added to the diagnostic spectrum harboring EWD-PTC and FVPTC. We report this case, because EWD-PTC is different from FVPTC in its papillary architecture, and also from WDT-UMP in its recurrence and metastatic pattern...

The RET receptor tyrosine kinase mediates cell proliferation, survival and migration in embryogenesis, and is implicated in transformation and tumour progression in multiple cancers. RET is frequently mutated and constitutively activated in familial and sporadic thyroid carcinomas. As a result of alternative splicing, RET is expressed as two protein isoforms, RET9 and RET51, which differ in their unique C-terminal amino acids. These isoforms have distinct intracellular trafficking and associated signaling complexes, but functional differences are not well defined...

We review the clinical and pathologic features of seven cases of papillary carcinoma of the thyroid that invaded the trachea and were treated by thyroidectomy, airway resection with reconstructive surgery over an interval of 15 years. We depicted the peculiarity of invasion of well differentiated papillary thyroid carcinoma (PTC) cells is perpendicularly oriented to the tracheal lumen, in between cartilaginous rings, along blood vessels and collagen fibers. Tracheal rings appear non-infiltrated in all histological sections of well differentiated PTC infiltrating the trachea...

INTRODUCTION: The number of patients diagnosed with solid carcinomas is increasing, and the most common site of metastasis is the lungs. It is often difficult to make a differential diagnosis between primary lung carcinoma and metastatic lung tumor in using histological examination and by determining their immunohistological status. PRESENTATION: A 64-years-old man presented with dyspnea with chest computed tomography (CT) findings of a pulmonary tumor, and afterwards suffered from a sudden bowel hemorrhaged due to colorectal carcinoma...
