Expression of E-cadherin in prostate cancer in formalin-fixed, paraffin-embedded tissues: correlation with pathological features

Aims: E-cadherin has been studied recently as a potential marker for tumour progression. The present study aimed to assess the expression of E-cadherin in formalin-fixed and paraffin-embedded radical prostatectomy specimens and to compare its expression with the pathological stage and Gleason score

Prenatal Sonographic Diagnosis of Multicystic Congenital Mesoblastic Nephroma

The authors report an unusual presentation of congenital mesoblastic nephroma as a multilocular cystic renal lesion. Prenatal sonography revealed a unilateral, encapsulated, multilocular cytic mass with solid components measuring 5.7 x 5.4 x 4.3 cm in the left renal fossa. There was no increase in vascularity and no signs of hydrops fetalis. On the forth postnatal day left-sided radical nephrectomy was performed and histopathological examination revealed cellular type congenital mesoblastic nephroma. A multicystic appearance is rare as the vast majority of prenatally diagnosed congenital mesoblastic nephroma cases presented in the literature are of the classic type with solid homogenous or heterogenous appearence.

The prognostic significance of angiogenesis and the effect of vascular endothelial growth factor on angiogenic process in Wilms' tumour

Aims: There is a subgroup of patients with Wilms' tumour (WT) having favourable clinicopathological features but adverse outcome. We aimed to investigate the prognostic significance of angiogenesis and whether it can be used for predicting which patients will fall into this category, and the possible role of vascular endothelial growth factor (VEGF) on angiogenesis in WT

An intrapericardial teratoma with endocrine function

Intrapericardial teratoma was diagnosed in a nine-year-old male infant with a three-month history of labored breathing and cough. The tumor was completely resected and found to be a mature teratoma, containing pancreatic tissue and producing insulin. A few glucagon and somatostatin containing cells were also present in the periphery of the islets. Postoperative course was uneventful. This is to our knowledge, the first report of an intrapericardial teratoma with such endocrine activity
