LYMPHANGIOMA OF THE COLON DIAGNOSED BY ENDOSCOPIC ULTRASONOGRAPHY (EUS)-REPORT OF TWO CASES-

Abstract

Two cases of lymphangioma of the colon were clearly diagnosed by endoscopic ultrasonography (EUS). The 1st case, a 67-year-old male was admitted complaining of constipation and barium-enema examination and endoscopy revealed a soft submucosal tumor located at the ascending colon. As EUS showed multiple echo free spaces in the submucosa of the tumor and no abnormal findings were found by angiography, the tumor was finaly diagnosed as lymphangioma. Transendoscopic polypectomy was performed and histopathological examination revealed cavernous lymphangioma of the colon. The 2nd case, a 45-year-old woman was admitted into our hospital for the therapy of pyelonephritis. Extra-abdominal ultrasonography and CT scan showed polycystic lesion in the left flank. Barium-enema study and colon fiberscopy revealed a few cystic submucosal tumors at the descending colon. By EUS and angiography, a diagnosis of extramural and intramural lymphangioma of the descening colon was made. A cavernous lymphangioma was confirmed by histopathological examination of the resected colon.
