Introduction: Mucinous ovarian cystoadenoma with stromal luteinization and hilar cell hyperplasia is a rare cause of hirsutism and virilization and only few cases are described in literature. We present a rare case of mucinous cystadenoma with hypertestosteronemia.A 38-years old woman came to our observation for severe hirsutism and oligomenorrhea. Hormonal work-up showed severe hypertestosteronemia (total testosterone: 4.39 ng/ml) with high levels of DH...

Context. The routine measurement of serum calcitonin (CT) has been proposed for patients with nodular goiter (NG), to detect unsuspected medullary thyroid carcinoma (MTC) before surgery. Objective To assess the prevalence of hypercalcitoninemia and MTC in NG patients; to compare the ability of CT measurement and fine needle aspiration cytology (FNAC) to predict MTC; to identify age groups of NG patients who should be better candidates than others to undergo routine measurement...

Introduction: Medullary thyroid carcinoma (MTC) and C cell hyperplasia (CCH) have a variable clinical presentation and prognosis and few data are available on the correlation between immunohistochemical characterization (IIC) and clinical behavior.Aim: We studied the clinical and morphological characterization of CCH and MTC and we evaluated IIC expression of PTTG-1, SSTR2A, VEGFR-1, VEGFR-2 and VEGFR-3 in 23 cases of CCH and/or MTC, correlating it with ...
