Urachal carcinoma is a rare and aggressive tumor, involving the urachus and the bladder. Symptoms of urachal carcinoma usually appear at later stages of the disease; therefore, these tumors are diagnosed in advanced stages, providing limited options for curative treatment. We report the clinical case of a 60-year-old man with a urachal carcinoma which presented as a mass of the abdominal wall invading the transverse colon, creating an enterocutaneous fistula. The patient underwent an en-bloc resection of the mass, segmentary resection of the transverse colon, and partial cystectomy.
Keywords: aggressive tumor; atypical presentation; enterocutaneous fistula; surgery; urachal carcinoma.
