Abstract
Here we report the case of a male patient in his sixties who underwent emergency surgery for perforated sigmoid colon cancer. Hartmann's operation was performed, and he developed skin metastases at the descending colostomy postoperatively. Transverse colostomy was performed for colon obstruction due to a recurrent tumor. The descending colostomy with mucous fistula had a distinct odor with considerable amounts of exudate. Mohs micrographic surgery with Mohs paste reduced the size of the malignant fungating wounds, odor, and exudates. His stoma became more easily manageable at home and his activity improved.
