Classically characterized by its papillary appearance, papillary thyroid carcinoma is the most common malignant neoplasm of the thyroid. Several variants of papillary carcinoma have been described considering size (microcarcinoma); nature of the tumor boundaries (encapsulated); architecture (follicular, macrofollicular, cribriform-morular, solid, micropapillary); cellular characteristics (tall ...
Background. Granulosa cell tumors (GCTs), representing ~2% of ovarian tumours, are poorly understood neoplasms with unpredictable and undetermined biological behaviour. Design. 5 unusual presentations of GCT and a retrospective 14-year (1997-2011) surgical pathology review based on patient sex, age, tumour type and concurrent pathology findings are presented to discuss the "myths and realities"...
Recent genome-wide association studies have identified several single nucleotide polymorphisms in the forkhead box E1 gene (FOXE1) locus, which are strongly associated with the risk for thyroid cancer. In addition, our recent work has demonstrated FOXE1 overexpression in papillary thyroid carcinomas. To assess possible contribution of Foxe1 to thyroid carcinogenesis, transgenic mice overexpress...
Heterogeneous Periostin Expression in Different Histological Variants of Papillary Thyroid Carcinoma
Background Periostin (PN) epithelial and stromal overexpression in tumor pathology has been studied according to tumor growth, angiogenesis, invasiveness, and metastasis, but a limited number of studies address PN in thyroid tumors. Aim Our study aimed to analyze PN expression in different histological variants of PTC and to correlate its expression with the clinicopathological prognostic fac...
Pelvic ultrasound scanning in asymptomatic adult-type granulosa cell tumor: A case report and review
Background: Ovarian cancer is common amongst women worldwide. In Indonesia, it the fourth most female with a 5-year survival rate of 45%, but can reach up to 92% if treated early. Granulosa cell tumors (GCT) arise from sex-cord and are considered malignant. This study presents rare case asymptomatic adult-type granulosa tumor in an elderly lady diagnosed during routine pelvic ultrasound scannin...
In modern clinical practice, thyroid incidentaloma is an unpalpated node in the gland, which detected accidentally by technical means of imaging when examining a patient for other, non-thyroid diseases. Its dimensions are limited to 10mm, limit above it can already be palpated qualified professional. author’s view, such definition narrows concept incidentaloma, primarily from nosological point ...
DESIGN The cytological diagnosis of oncocytic/Hurthle cell neoplasms (OCN) represents a challenge with which cytopathologists face up to in their practice. The majority of these lesions undergo surgery for a definitive characterization of the nature mainly due to their more aggressive behavior than other malignant follicular lesions. In this study, we aimed at the evaluation of the effective ma...
