Introduction: A case report of 25 yrs-old man with pedunculated exogastric leiomyosarcoma (with acute onset) surgically treated is presented.
Case Report: The patient was operated after clinical, instrumental and blood sample tests. We performed a 5 cm wedge resection of the stomach in continuity with the omentum.

Background: Malignant gastrointestinal stromal tumors (GISTs), previously termed leiomyosarcomas or epithelioid leiomyosarcomas, are known to show wide variability in their malignancy. We evaluated the clinicopathological features of a large number of primary malignant gastric GISTs to clarify which features were independent prognostic factors.
Methods: Clinicopathologic features (age, sex, tumor location, mode of growth and size, surgical method, ulceration, cell type, nuclear atypia, cellularity, mitotic index, growth pattern, necrosis, hemorrhage, direct tumor invasion, peripheral lymphoid cuffing, expression of alpha-smooth muscle actin [alpha-SMA], desmin, caldesmon, vimentin, CD34, c-kit protein and s-100 protein, and MIB-1 index) were evaluated by multivariate analysis in 140 patients with resected primary malignant gastric GISTs identify independent prognostic factors.

This collective review includes all available case reports of smooth muscle (stromal) tumors of the stomach in the world literature from 1762 to 1996. It updates our previous review from 1767 to 1959. Overall, we identified 2189 patients with leiomyoma (LM) and 1594 with leiomyosarcoma (LMS).

A case report and review of the literature on pedunculated exogastric leiomyosarcomas are presented. Although about one-fourth of the stromal tumors (common leiomyomas and leiomyosarcomas) of the stomach grow in an exogastric configuration, pedunculated exogastric leiomyosarcomas are extremely rare. At present there is no evidence of intraperitoneal seeding from exogastric leiomyosarcomas.

Slow intraperitoneal haemorrhage following blunt abdominal trauma may present as haemorrhagic ascites. Such haemorrhage is usually due to rupture of spleen, liver or damage to small bowel mesenteric vasculature. We encountered a patient with bleeding from ruptured exogastric leiomyoblastoma.
