Cloacogenic Polyps are characterized by the presence of inflammatory lesions in the lower rectum, and the anal transition zone. The polyps can prolaps; this is due to the malfunction of the internal anal sphincter; and the smooth muscle that covers the rectum. This is the result of the chronic inflammatory process. The lesions are more common in women during the third and fourth decade of life, however lesion have been described in 10 and 83 year olds. 85% lesions are located above the anal border and predominantly in the anterior lateral wall. The polyps vary in size from 3-4 cm in diameter, and have a sessile appearance. 10-year-old female presents with a 3-month history of irregular abdominal pain, with occasional vomiting, constipation, and occasional diarrhea. This entity of colon polyps is somewhat rare, and is seen in young adults; however its presence in infancy requires that we think of this entity when we formulate our differential diagnosis. Due to the character of the lesions, this entity could be confused with colorectal malignant tumors. All children and infants with a rectal mass, and blood in their stools should get a biopsy sent for histopathology. This technique can aid in analyzing the origin of the lesion.
