Cavernous hemangioma of the stomach: a case report and review of the literature.

A cavernous hemangioma of the stomach in a 41-year-old Japanese man was reported. The patient had numerous hemorrhagic telangiectasias in the skin and was also diagnosed as having a submucosal tumor of the stomach by an incidental upper gastrointestinal X-ray study. Wedge resection of the stomach was performed. The tumor was located in the submucosal, proper muscular and subserosal layers. The resected specimen showed proliferation of vascular spaces lined with a layer of endothelial cells and filled with red blood cells together with a partially calcified thrombus. The histopathologic diagnosis was cavernous hemangioma of the stomach with calcified thrombus. The patient has been doing well for twenty years. We report the case and briefly review the literature.
