Abstract

Two cases of retroperitoneal leiomyosarcoma are reported. Patient 1, a 68-year-old man, was admitted to the hospital because of a left upper abdominal mass.<br>Abdominal echo and CT scan showed giant masshaving necrotic change. The tumor 16×15×19cm in size and developing in the retroperitoneum was removed with the body and tail of pancreas, and spleen tran-speritoneally.<br>Patient 2, a 65-year-old man, was admitted to the hospital because of tarry stool and fatigability.<br>Abdominal echo and CT scan showed a well demarcated large abdominal mass accompanying with colonic gas. Intraoperative findings showed that the tumor invaded the second portion of duodenum and pancreas head. The tumor 13×7×6cm in size, was removed by partial resection of the duodenum and pancreas tran-speritoneally.<br>The pathological diagnoses of case 1 and 2 were retroperitoneal leiomyosarcoma.<br>Postoperative courses of both patients were uneventful.<br>Histological grading is the Determinant prognostic factor for retroperitoneal sarcomas.<br>We would emphasize the importance of early detection and if necessary, radical resection as much as possible which is the most effective and available treatment.
