[Ceccum leiomyoma: an unusual cause of intestinal occlusion in adults]

Cecal leiomyoma is a very rare benign tumor of the colon, constituted by a proliferative process of smooth muscle that originates from the muscularis propria or the muscularis of the cecum mucosa. These are often asymptomatic tumors that are found incidentally during screening studies or in the context of some other pathology. In cases with clinical expression, it commonly presents as chronic abdominal pain or a palpable abdominal mass. Infrequently it manifests as complications such as intestinal perforation, intestinal bleeding, or intestinal obstruction that require surgical treatment.

We present the case of a 25-year-old woman who came to the Central Guard service of the institution for abdominal colic pain of 48 hours of evolution associated with vomiting and abdominal distention. The videolaparoscopic surgical approach was decided in which an abdominal mass was identified at the level of the ileoceccal valve. Conventional right hemicolectomy with proximal loop ileostomy was performed with good postoperative evolution. Histopathological examination of the resected specimen revealed a benign ceccum leiomyoma.

The patient resolved her acute abdominal symptoms without complications and was discharged on the 5° postoperative day.

The scarcity of studies and bibliography related to this infrequent pathology denotes the need to elaborate new studies of greater scope that offer answers to the questions and controversial aspects that still persist in relation to the clinical, diagnostic and therapeutic management of benign cecal tumors of mesenchymal lineage.
