Introduction: Papillary thyroid carcinoma can be found very rarely in a thyroglossal duct cyst (TDC) (1%), this cancer variant being the most common type. Although, most of the TDC develop in the midline of the thyroglossal duct (~70%), some cysts occur off midline, within 2 cm of the midline.Case presentation: The female patient of 34-year-old presented at the Maxillofacial Surgery Department in October 2014, with a right submandibular painless neck mas...

Introduction: CD56 (neural cell adhesion molecule/NKH1/LEU19 and LEU7/NHK-1) is an antigen related to follicular epithelium differentiation.Materials and methods: We evaluated the expression of CD56 protein in normal follicular thyroid tissue, 15 non-neoplastic thyroid lesions (nodular hyperplasia–NH, Graves–Basedow disease (GB) and chronic lymphocytic/Hashimoto is thyroiditis (HT) and 38 thyroid neoplasias derived from follicular cells (25 PTC...

Introduction: Thyroid follicular adenomas (FA) and adenomatous nodules (AN) – lesions frequently found in areas with iodine deficiency, can be normo-/hypofunctioning (scintigraphically cold – SCN) or hyperfunctioning (scintigraphically hot – SHN) nodules.Aim: Evaluation of proliferation potential in thyroid nodules on tissue samples obtained at surgery from euthyroid patients clinically diagnosed with SCN and from patients with thyroid hyp...

Introduction: Cytokeratin-19 (CK19), p53 and Ki-67 are some of the proposed markers for differentiating benign from malignant thyroid tumors.Material and method: We evaluated the tissue expression of the three markers in 60 thyroid lesions including: 8 cases of nodular hyperplasia (NH), 16 follicular adenomas (FA), 26 papillary carcinomas (PC) and 10 follicular carcinomas (FC). Tissue sections fixed in formalin and embedded in paraffin were immunohistoch...

Introduction: Primary hyperparathyroidism (PHP) affects predominantly the adult age (incidence 1/10 000) and it is unusual.The aim of the study: Is to present a rare pathology in a child, which implied interdisciplinary collaboration.Material and method: We present a teenager girl of 16 years old, diagnosed with osteomalacia after a thoracic and pelvis trauma, based on knee and pelvis radiographs (diffuse bone demineralization, tra...

Carcinoid tumors are distinct neuroendocrine neoplasms with characteristic histological, clinical and biological features.Material and methods: An extremely rare case of a primary carcinoid tumor arising in a mature cystic teratoma is reported. A 23-year-old woman was admitted with pain in the lower abdomen and for further examination of a tumor in the left anexa. Transabdominal ultrasonography demonstrated a cystic mass measuring 110/70 mm, with irregul...

Purpose: The purpose of this study was to evaluate the histologic spectrum of stromal–epithelial patterns of invasion in ovarian serous and mucinous tumors of low malignant potential.Materials and methods: We retrospectively analyzed 31 cases of borderline ovarian serous and mucinous tumors diagnosed of the Pathology Department of County Hospital Timisoara in a period of 5 years, between 2003 and 2007. Epithelial architecture, the patterns of stroma...

Introduction: The value of microvessel density (MVD) as a prognostic factor in thyroid carcinomas, and its role in the development of metastasis, remain controversial.Aim: Determination of the relationship between MVD, the histological subtype of PTC, the presence or absence of metastasis in cervical lymph nodes (LN), the recurrence of the disease and AMES prognostic index.Material and method: The study included 32 patients with PT...

Introduction: The mammary cancer is the most frequent malign tumor encountered in females, characterized by a high distant metastasis tendency. Among the potential prognosis factors, we mention the biomarkers that measure or are associated with biologic processes involved in the tumorous progression. The study analyzes the p53 protein’s positivity in correlation with the mammary cancer’s classical prognosis factors: the hystologic type, the histopathologic degree, th...
