CONTEXT Heterotopic pancreas is defined as pancreatic tissue found out of the pancreas proper with no vascular or anatomical connection. It is a rare clinical entity and can be found at any portion of the alimentary system. CASE REPORT We describe a case of Meckel's diverticulum with heterotopic pancreas who presented massive lower gastrointestinal bleeding. CONCLUSION Lower gastrointestina...

A 10-year-old boy presented with a painless left scrotal mass that had been present for 2 years. Ultrasound examination revealed 2 left testes measuring 2.4 ml and 1.0 ml with the same echogenicity. Atsurgery, there were 2 similarly sized testes connecting with other spermatic vascular, but the supernumerary testis had no connection with the vas deferens. Histological findings showed immature t...

Ectopic liver is a rare clinical entity, which may be rarely of clinical importance. It is generally reported to be small in size and without a connection to the mother liver. A case of an incidental ectopic liver nodule that was connected with a vascular peduncle to the Couinad segment IVa of the liver has been reported. Microscopic examination revealed chronic inflammatory changes, which shou...

Heterotopic, aberrant or ectopic pancreas is defined as the presence of pancreatic tissue in topographic anomaly, with no anatomical, neural or vascular connection to the normal pancreas. It is a rare condition found mainly in stomach, duodenum and jejunum. Ileal heterotopic pancreas is an uncommon condition and has been rarely reported in children so far. Hereby we report a case of heterotopic...

An arteriovenous malformation is an anomaly of capillary development that results in a direct connection between branches of an artery and veins, with no intervening capillary network. Vascular malformations of the mediastinum presenting as mediastinal masses are very rare. We report a histologically proven case of a posterior mediastinal arteriovenous malformation in a 42-year-old man that was...

Dear Editor, Heterotopic pancreas is defined as pancreatic tissue found outside the pancreas without any anatomical or vascular connection with the main pancreas.1 Heterotopic pancreas is also known as the ectopic pancreas, aberrant pancreas and accessory pancreas.2 It can occur at any part of the gastrointestinal tract with 90% encountered in the stomach, duodenum and the jejunum.3-5 The entit...

kaposiform hemangioendothelioma (khe) appears as a single lesion at birth or early infancy in an equal sex ratio. a rare aggressive vascular proliferation has been recognized as a separate entity from other childhood vascular neoplasm. a 3-year-old iranian boy with a rapidly enlarging mass in his (posterior aspect of skull at the midline) skull was present here. physical examination revealed a ...

background and objective: vascular endothelial growth factor (vegf) is a cytokine which is overexpressed in many malignant cancers including leukemia. vegf plays an important role in tumor invasion and metastasis. determination of the pattern of vegf expression in human leukemic cell lines could be useful not only in screening of new antileukemic agents but also to study the mechanism of their ...

objective: to evaluate the adnexal masses with conventional gray scale and color doppler flow imaging and to assess their diagnostic reliability to differentiate benign and malignant adnexal masses. materials and methods: we evaluated 30 patients with adnexal mass. morphological characterization of the mass was done using sassone score. color doppler parameters noted down in each patient and ca...
