INTRODUCTION Thyroid angiosarcoma is a malignant neoplasm, which usually shows local aggressive behavior and associated with a high recurrence rate. It was originally described in the Alpine region and extremely rare in other parts of the world. CASE PRESENTATION An asymptomatic 61-year-old woman presented with a right lobe thyroid nodule with fine needle aspiration cytology indicating "suspi...

INTRODUCTION Thyroid malignomas are a heterogeneous group of neoplasm consisting of most frequent differentiated encountered carcinomas, papillary and follicular thyroid carcinoma, then medullary thyroid carcinoma originating from neuroendocrine calcitonin-producing C-cells and rare forms of thyroid lymphomas arising from intrathyroidal lymphatic tissue, thyroid sarcomas and poorly differentiat...

Highly differentiated thyroid cancer is a common endocrine neoplasm with favorable prognosis. However, errors in the treatment of this pathology can significantly worsen patient’s quality life. Patient V., 65 years old, underwent an operation for papillary injury to recurrent laryngeal nerve 2015. Only 6 months later, RAI therapy was performed insufficient dose RI, and levothyroxine prescribed at t...

RATIONALE Ectopic thyrotropin (TSH)-secreting pituitary adenomas are exceedingly rare. To date, there are only 6 cases reported. Here, we describe an even rarer ectopic TSH-secreting pituitary adenoma (TSH-oma) concomitant with papillary thyroid carcinoma. PATIENT CONCERNS A 27-year-old female was admitted to the hospital in 2002 for neck enlargement and palpitation. Thyroid function test sho...

With fewer than 40 cases described in the otolaryngology literature, mixed medullary papillary thyroid carcinoma represents a rare but phenotypically distinct tumor. While isolated medullary carcinoma may be admixed with normal follicular structures, true mixed carcinoma displays morphological and immunological characteristics of medullary and papillary carcinoma within a single lesion. We repo...

The aim of of the study was to investigate the possible changes of primary fine needle aspiration (FNA) diagnoses after subsequent check ups. We investigated 948 thyroid nodules and the main indications for repeat FNAs were inadequate/indeterminate FNA findings and growing nodules at ultrasound check up. FNA findings were subdivided into inadequate, benign, low-risk lesion (includes cellular fo...

hbme-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. the antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. hbme-l has also been reported to strongly and uniformly stain papillary and fo...
