Parathyroid carcinoma (PC) rarely presents with metastasis at diagnosis and usually in patients also having gross local invasion.Case presentation: We report the case of a 51-year-old postmenopausal woman presenting at our institution in June 2019 with symptomatic hypercalcemia (fatigue, polyuria, constipation and bone pain), but with a surprisingly good general condition. She had been treated with bisphosphonates for osteoporosis (DXA: LS T score &#8722...

Introduction: Riedl thyroiditis is a rare thyroid disorder of unknown etiology (autoimmune assumed), in which the gland is invaded by dense fibrous tissue, that extends in the vicinity. Goiter is usually painless and can be accompanied by other fibrous affections (retroperitoneal fibrosis, sclerosing cholangitis, mediastinal fibrosis).Case presentation: Patient, 39 years old, smoker, from nonendemic area, initially presents in 2011 with voluminous polyno...

Medullary thyroid carcinoma (MTC) is an aggressive form of malignancy, virtually incurable except by complete surgical resection. With insidious onset and occasional rare clinical variants, it is often diagnosed late in the course of disease and has a poor prognosis. We aimed to evaluate diagnostic efficiency, treatment modalities and outcome in patients admitted to our department between 2004 and 2015, diagnosed with MTC, with emphasis on rare clinical presentations. We ident...

Introduction: The coexistence of hyperthyroidism and thyroid cancer is rare (below 2% of cases with hyperthyroidism). If this association predisposes to larger, multifocal or more aggressive cancer (especially in Graves’ disease) is a matter of debate. We describe the clinical and hystopathological aspects and evolution in two patients with hyperthyroidism and thyroid cancer.Patient 1, a 42-year-old woman, was diagnosed in 2008 with Graves’ dis...

Often discovered incidentally, small foci (≤2 cm) of papillary thyroid carcinomas (PTC) are its most frequent presentation. Despite favourable prognosis, the extent of surgery and use of radioablation is still controversial.Objective: Prospective cohort study of all patients admitted between 2007 and 2011, for thyroid surgery in the Institute of Endocrinology, Bucharest, Romania, and had pT1a or pT1b PTC.Patients and methods:...

Background: Differentiated thyroid cancer (DTC) encompases a wide spectrum of disease from clinically insignificant micro-tumors to aggressive cancers. The molecular signature can be used to predict tumor behaviour, and the co-existence of BRAF and TERT promoter mutations has been identified as a marker of adverse prognosis, but we have yet no available molecular data for the Romanian population.Objectives: To determine the prevalence of BRAF V600E and T...

Introduction: RET proto-oncogene is situated on chromosome 10 and encodes a tyrosine kinase receptor. A germline mutation of RET leads to the appearance of MEN 2 syndrome or familial medullary thyroid carcinoma (MTC). One of the most common germline mutation occurs in codon 634. Pheochromocytoma penetrance for codon 634 mutation was demonstrated to increase with age up to 88% by age 77 years.Aim: To present two familial cases of RET mutation illustrating...

Introduction: Clear cell renal carcinoma (ccRCC) is a subtype of renal cell carcinoma, the most frequent one (80%) and usually affecting only one kidney. It is twice as common in men than women between 50 to 70 years old. It can be associated with some genetic conditions that predispose patients to ccRCC, like Von Hipple-Lindau disease. Some clinical observations and molecular studies raised the hypothesis that RCC is a hormone−dependent tumor.Case...

Background: Papillary thyroid cancer (PTC) incidence has increased substantially over the last decades. Although 4% of thyroid cancers may induce a sarcoid reaction in the thyroid gland, sarcoidosis (SA) as a disease may exist with PTC, although causality remais uncertain and their coexistence is rarely reported in the literature. They occurs in both genres, between 30–40 years, but females are more predisposed.Case presentation: A 65-year-old man, ...

Introduction: Ectopic thyroid tissue (ETT) is a rare entity; it is more frequent in women (80%) and is usually located along the obliterated thyroglossal duct. ETT in the midline is even rarer (1.79%). Incidence of malignancy in this group is lower than in orthotopic thyroid nodules.Case report: A 40 years old woman, resident in iodine sufficient area, but originating from an iodine deficient area, presented for a midline neck mass. TSH and FT4 were meas...
