title: A malignant gastric leiomyoblastoma presenting as an infected pseudocyst of the pancreas.
abstract: Malignant gastric leiomyoblastoma (epithelioid leiomyosarcoma) is an uncommon smooth muscle neoplasm which is generally slow growing but capable of attaining large size. When these tumors project extrinsically from their site of origin in the gastric wall, they present diagnostic difficulty to the clinician and radiologist. This case report documents a highly unusual example of such a tumor which presented as an infected pancreatic pseudocyst and produced symptoms related to inferior vena caval compression.
