Posttraumatic colonic polyps with skin heterotopia
- 8 Downloads
A case of posttraumatic colonic polyps with skin heterotopia is reported. A 35-year-old man was the victim of a grenade explosion, which caused evisceration and partial amputation of the right colon. Twenty-five months after the accident, hypochromic anemia developed because of three polyps in the ascending colon. Histology documented the presence of sebaceous glands and keratinized epithelium, suggesting a graft of skin fragments on the colonic mucosa. Such a skin heterotopia has never been reported.
