A 26-year-old man was admitted to our hospital with an anal tumor being present from 1 year ago. Rectal examination revealed a 5 cm mass that protruded from the anus on the anal skin at the 5 o'clock position. The mass was brown with a wrinkled surface, resembling testicles, and the root had a long clear stem that was connected to the vicinity of the anal papilla. Since it was expected that it could be safely removed through root ligation, it was resected in the outpatient department without anesthesia. The pathology revealed a fibrovascular polyp, which is a so-called anal polyp. Anal polyps are enlarged anal papillae that are usually approximately 2-5 mm in size and very rarely larger than 2 cm. Those with a size ≥3 cm should be distinguished from malignant tumors such as leiomyosarcoma, anal canal cancer, and malignant lymphoma. In this case, it was 5 cm large, and surgery was indicated. It had a testicle-like shape, different from the usual smooth surface, had a long stem, and could be resected immediately on the day of the first visit without anesthesia. Since it was an anal polyp with a peculiar shape, we report it with some bibliographical considerations.
