Primary gastric leiomyosarcoma in young revealed by a massive hematemesis.

INTRODUCTION: Leiomyosarcomas are one of the most common soft tissue sarcomas, usually seen in deep, soft tissues of the extremities and retroperitoneum. Leiomyosarcoma primarily involving the gastrointestinal tract is uncommon. We present here a rare case of gastric leiomyosarcoma revealed by a massive hematemesis in a young woman. CASE REPORT: We present a case of primary gastric leiomyosarcoma in a 16-year-old woman who presented with massive hematemesis. Computed tomography scan examination revealed a tumor mass located in the anterior wall of the upper body and protruding into the lumen. The patient was treated by subtotal gastrectomy. The histological examination confirmed the diagnosis of leiomyosarcoma of the stomach. DISCUSSION: Primary stomach leiomyosarcoma is rare, accounting for only 1% of gastric tumors. Endoscopic ultrasound and biopsy are helpful in establishing the diagnosis. Surgical resection is the treatment of choice for gastric leiomyosarcomas.
