Our results indicate that Moh's micrographic surgery with paraffin-embedded sections may be the method of choice to treat dermatofibrosarcoma protuberans with a low recurrence rate, while preserving surrounding normal healthy tissue.

Splenic rupture (SR) after colonoscopy is a very rare but potentially serious complication. Delayed diagnosis is common, and may increase morbidity and mortality associated. There is no clear relation between SR and difficult diagnostic or therapeutic procedures, but it has been suggested that loop formation and excessive torquing might be risk factors. This is a case of a 65-year-old woman who underwent endoscopic submucosal dissection (ESD) for lateral spreading tumor in the descending colon, and 36 h afterwards presented symptoms and signs of severe hypotension due to SR. Standard splenectomy was completed and the patient recovered uneventfully. Colorectal ESD is usually a long and position-demanding technique, implying torquing and loop formation. To our knowledge this is the first case of SR after colorectal ESD reported in the literature. Endoscopists performing colorectal ESD in the left colon must be aware of this potential complication.
