RESUMO
Henoch-Schonlein purpura is an immunologically mediated systemic leukocytoclastic vasculitis of small vessels that is characterized by symmetric nontraumatic, nonthrombocytopenic, painless palpable purpura on the lower extremities and buttock, arthralgias on usually the knees and ankles, gastrointestinal symptoms and glomerulonephritis. Although the jejunum and ileum are most frequently affected, any portion of gastrointestinal tracts may be involved. Generally, gastrointestinal manifestations of Henoch-Schonlein purpura are the edematous wall of involved bowel, submucosal hemorrhage and erosion. We experienced a 56-year-old man with Henoch-Schonlein purpura who initially presented acute abdominal pain with portal vein and superior mesenteric vein thrombosis.

Gastric glomus tumor is an uncommon benign, submucosal neoplasm and does not require radical surgical procedure. Because there are no specific clinical or radiologic features associated with the glomus tumor, it can be recognized only by its histologic characteristics. We report a 30-year-old woman who had 10 years history of epigastric hunger pain. Radiologically, a gastric submucosal tumor was discovered, which was suggestive of leiomyoma. Gastric antrectomy was performed. The tumor cells showed immunohistochemical and ultrastructural evidence of smooth muscle differentiation.
