The incidence of lymphangiomas in the gastrointestinal tract is low, particularly in the colon and rectum, and most cases are solitary. Lymphangiomatosis of the colon are encountered infrequently with only one report in the English literature, and polypectomy was performed for the diagnosis in that case report. However, trends in the diagnosis of lymphangiomatosis of colon have been changing since the development of endoscopic ultrasonography (EUS), and this case is the first in that lymphangiomatosis of the colon was diagnosed without invasive procedures. Here we describe the case of 31-yr-old woman with lymphangiomatosis of the colon with numerous polyposis-like appearing lesions diagnosed by endoscopic ultrasonography and a colonoscopy.

Schwannomas are rare tumors derived from the cells of Schwann which form the neural sheath. Some patients with gastrointestinal schwannoma have been previously reported in the literature. However, schwannomas of the colon are extremely rare. We herein describe a case of schwannoma of the colon. A 49-year-old woman was admitted with complaint of abdominal pain and investigations revealed the presence of a 4 cm sized mass in the ascending colon. Following right hemicolectomy, histopathology and immunohistochemistry confirmed the colonic lesion to be a benign schwannoma. There was no evidence of specific complication or recurrence until now.
