Introduction
Colon and rectum cancer is the second most prevalent neoplasia in Spain, affecting 49 cases per 100.000 habitants. Fifteen percent also carry colostomy, which can favor oncologic free margins and endoscopic follow up. Nevertheless, the appearance of a new neoplasia at the colostomy site is not to be neglected, since 15 cases have already been described in the literature (1).
Clinical case
A 60-year-old woman had been through Miles abdomino-perineal resection due to neoplasia of the rectum, transverse segmentary resection for colon neoplasia and right hemicolectomy for caecal adenoma at the age of 31, 35 and 53 respectively.
After 5 years, at a routine colonoscopy, two polypoid formations were identified and resected being the rest of the exploration normal.
At the following visit an exophytic, granulomatous, irregular and painless lesion was detected in the colostomy margin (Figs. 1 and 2). The biopsy revealed an intramucous adenocarcinoma with focal submucous infiltration. The patient had a resection of the previous stoma and a new terminal colostomy was performed, without the administration of adjuvant chemotherapy. After a 2 year-follow up the patient is free from disease.
Discussion
Metachronic colorectal neoplasias represent three percent of all cases (2), lying exceptionally at the colostomy level (3,4). However, benign injuries as granulomas or irritative ulcers are quite frequent.
A proper exploration and biopsy of the suspicious stomal injuries should be performed systematically.
The treatment for this pathology is based on a free-margin surgery. Nevertheless, regarding its low incidence, there are no studies on the need to add adjuvant chemotherapy (5).
