A Rare Case of Perforated Descending Colon Cancer Complicated with a Fistula and Abscess of Left Iliopsoas and Ipsilateral Obturator Muscle

Abstract EN

Perforation of descending colon cancer combined with iliopsoas abscess and fistula formation is a rare condition and has been reported few times.

A 67-year-old man came to our first aid for an acute pain in the left iliac fossa, in the flank, and in the ipsilateral thigh.

Ultrasonography and computed tomography revealed a left abdominal wall, retroperitoneal, and iliopsoas abscess that also involved the ipsilateral obturator muscle.

It proceeded with an exploratory laparotomy that showed a tumor of the descending colon adhered and perforated in the retroperitoneum with abscess of the iliopsoas muscle on the left-hand side, with presence of a fistula and liver metastases.

A left hemicolectomy with drainage of the broad abscess was performed.

Pathologic report findings determined adenocarcinoma of the resected colon.
