Perú [online]. 2020, vol.40, n.4, pp.351-354. ISSN 1022-5129.  http://dx.doi.org/10.47892/rgp.2020.404.1173.

The case of a patient with ascending colon cancer and infiltration of the abdominal wall with a proliferative tumor on the skin is presented. This is an 83-year-old man who underwent surgery for an intra-abdominal abscess ten months before admission and develops a colocutaneous fistula. The patient presented a 10 cm diameter proliferative, multilobed, non-painful tumor on the flank and right iliac fossa; the biopsy revealed an adenocarcinoma. The colonoscopy revealed a 6 cm tumor in the ascending colon, the biopsy reported moderately differentiated adenocarcinoma. The tomography showed a neoformative lesion in the ascending colon and cecal region with dimensions of 52x46x44 mm with a 62 mm colocutaneous tumor course that ended at the cutaneous level in a 70 mm ovoid lesion. A right colectomy was performed with en bloc resection of the abdominal wall compromised by the tumor. The relationship between skin infiltration and a history of laparoscopic surgical drainage of an intraperitoneal abscess apparently caused as a complication of ascending colon cancer almost one year before admission is postulated. The drain used served as a route for infiltration into the abdominal wall.
