Abstract
Although solitary rectal ulcer syndrome (SRUS) has a characteristic pathologic findings on biopsy specimen, the diagnosis of which often is delayed because this syndrome is easily mistaken for rectal cancer, inflammatory bowel diseases or other forms of proctitis. The mucosal prolapse syndrome has been widely accepted because presence of rectal ulcer is multiple or absent, and this syndrome include related disorder like as colitis cystica profunda. Proctosigmoidoscopy can show variable lesion to differentiate SRUS, which has abnormal gross findings from ulcerative lesions to polypoid lesion, mild proctitis, thickened nodular folds. Endoscopic transrectal ultrasonography (ETUS) has been known to useful procedure to staging and follow up of anorectal carcinoma. ETUS could clearly delineate the rectal wall and its separate layers, and mucosal ulcers or changes in the rectal wall architecture. A 49-year-old female complained of rectal bleeding, mucoid stool and excessive straining with rectal pain. Proctosigmoidoscopic finding revealed irregular rectal ulcers mimicking malignancy. SRUS was diagnosed based on clinical symptom, rectal biopsy and ETUS.
