title: Trichoblastic carcinoma arising from colostomy.
abstract: Trichoblastic carcinoma is a rare skin cancer originating from hair germ cells. We report a case of an 84-year-old man who presented with a tumor on the stoma of the descending colon, which was preoperatively diagnosed as colon cancer. He underwent colectomy with adjacent skin, and the tumor was diagnosed as trichoblastic carcinoma by postoperative pathological examination. We are not aware of any similar cases published in the English literature. Therefore, we report this case because it is quite a rare condition.
