胃血管内皮腫の1例

A CASE OF THE HEMANGIOENDOTHELIOMA OF THE STOMACH

Ⅰ．はじめに

　血管由来の腫瘍が胃に発生することは比較的少なく，ことに分化度の低いtypeのもの，例えばhemangioendothelioma^1)～3)，hemangioblastoma⁴⁾は極めてまれである．

　本邦における胃の血管由来の腫瘍は26例が報告されており，このうち血管内皮腫は2例である．

　56歳の女子に発生した，胃のhemangioendotheliomaを報告し，若干の考察を加えたい．

　Most cases of the angiogenic tumor of the stomach have been considered to be congenital or hamartomatous in origin. The reported cases in Japan until 1968 were 26, of which 6 cases were glomus tumor, 4 cases were hemangiopericytoma, 3 cases were angiosarcoma, 4 cases were angioblastoma, 3 cases were hemangioma, 2 cases were hemangioendothelioma, and a case was hemangiosarcoma.

　In the present paper, a further case of hemangioendothelioma in a 56 year-old female is reported. The patient was hospitalized with complaints of epigastric discomfort, heart burn and hematemesis. Laparotomy was performed and a convex tumor protruding into the gastric cavity with 7×5×3 cm size was found on the greater curvature of the stomach.
