Gastric Leiomyosarcoma as a rare cause of gastric outlet obstruction and perforation: A case report

Abstract

Background: Gastrointestinal stromal tumours are the most common mesenchymal malignancies of the gastrointestinal (GI) tract and gastric leiomyosarcoma represent 1-3% of gastric malignancies. Case presentation. We report a case of a 69-year- old black African man who presented with a rare cause of gastric outlet obstruction and duodenal perforation. A Billroth- II gastrectomy was performed and histology confirmed a gastric leiomyosarcoma. Conclusions: It is important to identify the gastric leiomyosarcoma which is a variant of the more common malignant gastrointestinal stromal tumours as the pathogenesis and management are currently well established. As the facilities for differentiating these are not easily available in resource-limited areas gastrointestinal stromal tumours may remain underdiagnosed and undertreated. © 2014 Weledji et al.; licensee BioMed Central Ltd.
