Background & objective: Changes in submucosal vascularization and inflammation, determined by immunohistochemistry staining, were shown to be correlated with the development of dysplasia and invasiveness of epithelial cells in premalignant and malignant lesions. This study evaluated changes in sections routinely stained with Hematoxylin and Eosin (H&E;) in orde...

conclusion the involved liver with hht typically shows vascular shunting and biliary diseases. also, arteriovenous shunts may be vulnerable to biliary diseases. results (i) three types of shunting were found in the livers, including arteriovenous (hepatic artery to hepatic vein) in 6 cases, arterioportal (hepatic artery to portal vein) in 2 cases, and portal venous (portal vein to hepatic vein)...

Fibromuscular dysplasia is a rare, non-atherosclerotic non-inflammatory vascular disease that most commonly involves the renal arteries and carotid arteries, but has been described in nearly every vascular bed in the body. Complications of fibromuscular dysplasia include aneurysms and vascular dissection. We present a rare case of fibromuscular dysplasia involving the aorta, complicated by type...

Placental mesenchymal dysplasia is an underdiagnosed and a rare vascular anomaly of the placenta. It characterized by presence grape-like vesicles, which, on ultrasonography gives appearance partial mole. Histologically it can be differentiated mole absence trophoblastic proliferation. essential to make correct diagnosis as management outcome both these entities are vastly different. We present...

The article presents a clinical case of congenital arteriovenous dysplasia – Parkes Weber syndrome the lower extremities. features its picture and difficulties diagnosis are described. It is emphasized that rare disease vascular system, in some cases with absence typical manifestations combined other pathologies veins.

Hereditary Haemorrhagic Telangiectasia (HHT) is an autosomal dominant disorder characterized by vascular dysplasia. Hepatic Vascular Malformations (VMs) range from small telangiectases to significant shunting. Here we report two cases of HHT. Case 1 had diffuse ectasia the hepatic artery along its intrahepatic and extrahepatic course with a arterial aneurysm. 2 presented ileal telangiectases. K...

BACKGROUND AND PURPOSE Bone marrow-derived cells (BMDCs) home to vascular endothelial growth factor (VEGF)-induced brain angiogenic foci, and VEGF induces cerebrovascular dysplasia in adult endoglin heterozygous (Eng(+/-)) mice. We hypothesized that Eng(+/-) BMDCs cause cerebrovascular dysplasia in the adult mouse after VEGF stimulation. METHODS BM transplantation was performed using adult wi...
