Carcinoma of sigmoid colon after ureterosigmoidostomy.
An unusual case of adenocarcinoma of the colon in a 49-year-old man is described. The patient underwent ureterosigmoidostomy at the age of 3 years after a traffic accident. At the age of 49 years, he was admitted to a Department of Urology for treating urinary lithiasis. A chest x-ray and thoracic computed tomography (CT) showed some nodules in both pulmonary fields, while an abdominal CT was normal. The previous patient's history was ignored, the patient underwent thoracoctomy and a nodule was removed. The histology revealed a metastatic, moderately differentiated mucinous adenocarcinoma, probably of the bowel. A sunsequent colonoscopy was non-disclosing and the patient was thought to suffer from a carcinoma of unknown origin and received 6 cycles of chemotherapy with carboplatin and 5-fluorouracil. Five months after the end of chemotherapy he presented with an uncerated mass in the lower abdominal wall. A new CT scan revealed a solid mass in the pelvis with infiltration of the suprapubic region while a repeat colonoscopy showed an infiltrating mass in the sigmoid. Biopsies were obtained from both lesions and the histology was similar with that of the pulmonary nodule.
