ABSTRACT

Malignancy Patients who have had stoma surgery for bowel or urinary tract malignancy may develop secondary deposits within or around the stoma. This is probably more common with adenocarcinoma of the bowel ( Fig. 6.1 ). Such peristomal tumors may represent secondary (metastatic) deposits of tumor in the skin or, rarely, growth of residual tumor within the bowel. In a proportion of cases, such as that illustrated in Figure 6.1 , this may represent seeding of tumor to the skin at the time of stoma formation. Treatment is surgical.
