Laparoscopic Right Hemicolectomy to Curatively Treat Primary Leiomyosarcoma at the Ileocecal Valve

Abstract

Primary leiomyosarcomas of the colon (PLC) are rare tumors, representing 0.12% of all colon malignancies. We report a 59-year-old man with weight loss, mild anemia, and rectal bleeding. Colonoscopy revealed a 3.2 × 2.6-cm mass at the ileocecal valve. Histopathological examination of the biopsy showed a spindle cell neoplasm that stained positive for smooth muscle actin, caldesmon, and desmin. A diagnosis of PLC was made. Subsequently, a laparoscopic right hemicolectomy was performed, and no local recurrence was noted 6 months after the resection. Given the rarity of PLC, more studies on the clinical features and treatments of this tumor are warranted.

Totally laparoscopic resection using delta-shaped anastomosis of jejunal leiomyosarcoma with intussusception at the angle of Treitz: a case report

“…Although the number of reports on the LMS of the GI tract has been limited, the number of reports of minimal invasive surgery for the LMS of the GI tract have been recently increasing with favorable outcomes. A PubMed search using the key words "leiomyosarcoma" and "laparoscopic surgery" since 1998 revealed six case reports (seven patients) of laparoscopic resection of the LMS in the GI tract [6,9,11,[15][16][17]. Among them, two cases were located in the small intestine, one in the stomach, and the remaining four in the colon.…”
