Mucosal prolapse syndrome comprises a variety of clinical and histopathological entities, with mucosal prolapse as the underlying pathogenic mechanism. Due to variable clinical, endoscopic and histopathological presentation and rareness of symptomatic mucosal prolapse, misdiagnosis resulting in delayed or inappropriate treatment is frequent. This report describes a patient initially diagnosed with a colorectal polyposis syndrome consisting of multiple rectal hyperplastic and adenomatous polyps. But after careful review of medical history and histopathology, the patient was found to have a rare variant of solitary rectal ulcer syndrome presenting as rectal polyposis. The recognition of rectal polyposis as a manifestation of solitary rectal ulcer syndrome/mucosal prolapse syndrome will improve diagnosis and treatment and prevent inappropriate management of this condition.
