[Colonic cancer with infiltration to the abdominal wall: a diagnostic challenge]

We present the case of a 53-year-old woman with a time of illness of 20 months, characterized by pain at the site of surgical intervention for opened cholecystectomy 3 years ago, associated with a presence of a mass in said area, with the following abscess formation and fistulization of food content. Imaging studies revealed a mass dependent of the transverse colon, in contact with stomach and abdominal wall and presenting fistulas to the skin. Said mass was extracted during surgery with anatomopathological result of mucinous colon adenocarcinoma. The case represented a diagnostic challenge for the medical team and in view of the variaty of clinical manifestations of colonic cancer, we suggest that it should be consider as a differential diagnosis in cases of abdominal wall abscess and enteric fistulas.
