An Infant Case of Kaposiform Hemangioendothelioma Located in Descending Colon

Abstract

Kaposiform hemangioendothelioma (KHE) is classified as an intermediate malignancy and sometimes causes Kasabach–Merritt syndrome. The lesion in the intestinal tract has only been described in a few reports. We experienced treating a case of KHE, which located in the descending colon. A 5-month-old boy presented with bloody stool and his laboratory exams showed progressive anemia for 3 months. Thus, he was referred to our hospital. Colonoscopy revealed an elevated lesion with erosions and exposed vessels in his descending colon. Because conservative therapy failed and submucosal neoplasm was suspected, operative therapy was carried out. A single-hole laparoscopic-assisted surgery was performed. The descending colon was extracted and wedge resection of the lesion was performed. His postoperative course was stable, and he was discharged 7 POD. Because of the high frequency of recurrence of KHE, careful follow up is required.
