Inflammatory Cloacogenic Polyp Mimicking Anorectal Malignancy.

Inflammatory cloacogenic polyp is a polypoid protruding lesion arising from the transitional zone of the anorectal junction. It has a distinctive endoscopic, histological appearance, but it may macroscopically resemble anorectal malignancy. It is important to beware of the possibility of adenoma and malignancy when finding lesions at the anorectal junction. The management of inflammatory cloacogenic polyp is endoscopic or surgical excision. We report here on a 62 year old man who had an anorectal polyp. The initial impression was hemorrhoid or anorectal malignancy. He underwent surgical intervention, and the histology showed inflammatory cloacogenic polyp.
