title: Endoscopic ultrasonographic findings in rectal leiomyoma.
abstract: A 35 year old man visiting a hospital for his annual check-up in August 1992 was found to have a large rectal tumour on digital examination. Colonoscopy revealed a bulging lesion with normal mucosa. Endoscopic biopsy showed only normal tissue. Endoscopic ultrasonography demonstrated a large hypo-echoic submucosal tumour in the fourth layer (muscularis propria) of the rectal wall. Based on this endoscopic ultrasonographic finding, we diagnosed the tumour as leiomyoma pre-operatively. The tumour was excised by a trans-sacral local excision. The histological diagnosis of the resected specimen was cellular leiomyoma.
