Hemangioma (from the Greek. chylos - milky juice and angeion - vessel - a kind of lymphangioma growing from the milky vessels.
Hemangioma, like many other lymphangioma (see), occur on the basis of defect development of small vessels and not always are the true tumors. Proceed usually benign neoplasms; rare variants described malignant Hilarion - lymphangiectasia milky ways (for example, the thoracic duct).
Localized hemangioma mainly in the mesentery or a thin wall, rarely colon, in gland, retroperitoneal space. Occur in children and adults. The tumor usually sporadic, but occasionally there are multiple (in the mucosa of the small intestine in the elderly). The size of the tumor vary from pea to 20 cm in diameter. Hemangioma is a host, consisting of many different sizes cystic cavities with smooth walls, filled jeleznoi liquid, sometimes with blood. Microscopically cavity is lined flattened by endothelial cells, sometimes to the presence santonij single - and multi-core cells. Wall cavity presents fibrous tissue, often with hyalinosis; sometimes they meet the smooth muscle fibers.
Malignant hemangioma show considerable variability cells with the formation of very large, often multi-core elements. When hemangioma usually celebrate the expansion of the lymphatics below the tumor. Large tumors can cause complications: break the cyst wall with the development of peritonitis, bleeding in the tumor with acute hemorrhage, intestinal obstruction, torsion legs of the tumor necrosis her and peritonitis.
