MEN2A is an autosomal dominant inherited syndrome, caused by a gain of function germline mutation in the RET proto-oncogene, with multiglandular tumoral development. Although the presence of MTC is very high and 50% of patients present with pheochromocytoma, the penetrance of hyperparathyroidism is estimated to be between 9 and 34%. The clinical presentation of the syndrome varies widely even in members of the same family, because of the difference of gene penetration (1). In ...

Craniopharyngiomas are rare solid or mixed solid-cystic tumours. Although benign histologically, these tumours frequently shorten life and should be considered low-grade malignancies.We present the case of a 12-year-old boy diagnosed in 2008, at age 5, with a suprasellar tumour of 22/21/20 mm with mixed solid and cystic areas. The tumour was operated twice by left transfrontal approach in 2008 and right transfrontal approach in 2009. The pathology exam r...

Background: There are only few reports regarding the role of serum galectin-3 (Gal-3) as an early biochemical marker in thyroid carcinoma.Aim: To evaluate the potential overexpression of Gal-3 in sera from patients with confirmed diagnosis of papillary thyroid carcinoma (PTC).Patients and methods: We retrospectively investigated serum Gal-3 in 40 patients referred to the surgical department for thyroidectomy. Sera were collected be...

Introduction: Struma ovarii is a rare condition which elicited considerable interest because of its many unique features like its relationship to teratoma and differentiated thyroid cancer. The most common thyroid carcinomas to arise in struma ovarii are papillary and follicular.Objectives: We describe two patients with differentiated thyroid carcinoma originating from malignant struma ovarii.Results: Our index patient is a 32-year...

Introduction: Pheochromocytomas are rarely malignant, defined by the presence of cathecholamine – producing metastases. Malignant pheochromocytoma responds poorly to chemotherapy and radiotherapy. 131I-MIBG therapy can be used to prolong survival, with minor side effects.Case: A 45-years old woman known with malignant pheochromocytoma, with a long medical history, first came to our clinic in July 2012. Her diagnosis was suspected in 1999 ...

Background: Suitable postoperative radiotherapy (RT) of nonfunctioning pituitary macroadenomas (NFMAs) is still controversial, subjected to rapid technical and medical progress.Patients and methods.: We studied 87 patients with NFMA to identify factors affecting tumor control such as the time of RT and tumor pathology. Partial pituitary surgery was performed either by transfrontal (30 patients) or transsphenoidal (57 patients) approach. An immunoperoxida...

Introduction: Pegvisomant (PEG) is an efficient treatment for acromegaly but the recommendation for this treatment is less active due to its high cost. In Romania it is reimbursed in doses up to 30 mg s.c/day or as 40 or 80 mg/week in combination with a somatostatin analog (SSA).Design: Retrospective analysis of 18 consecutive patients treated with PEG for acromegaly (either as monotherapy, or in combination with SSA and/or cabergoline (CAB...

Introduction: The determination of basal and stimulated calcitonin (CT) is very important for the precocious diagnosis of medullary thyroid carcinoma (MTC) and for its dynamic follow-up. Unfortunately, monitoring is difficult when using assays with different detection systems. Our objective was to identify the correction factor between the reagents for CT measurement on the LiaisonXL and Cobase 601 assays (immunochemiluminescence, respectively electro-immunochemiluminescence)....

Background: Matrix metalloproteinase-9 (MMP-9) is an important mediator of invasion and metastasis in neoplasia. The single nucleotide 1562 C/T polymorphism in the promoter region of the MMP-9 genewas shown to increase gene expression and was studied as a susceptibility factor for various cancers.Aim: We aimed to evaluate the impact of the MMP-9 promoter genotype on the risk of developing papillary thyroid cancer (PTC) and to correlate cancer patient gen...

Introduction: Pheochromocytoma (PCC) has a wide spectrum of clinical manifestations, from insidious disease to extreme symptoms. Various mechanisms of catecholamine and other mediators actions were related to the diversity of PCC presentation.Aim: We describe a retrospective study, of patients with PCC from a tertiary hospital, focusing on clinical and biochemical characteristics of PCC depending on means of discovery.Material and ...
