The patient was a 66-year-old female. Her immunological fecal occult blood was positive. Digital examination revealed an elastic, pedunculated mass to the 6 o'clack direction. Colonoscopy disclosed a hemispheric, broad-based, and protruded lesion 4cm from the anal verge. The lesion had a smooth surface with an erosion in its center. A subrnucosal tumor, especially a carcinoid or myogenic tumor or a malignant lymphorna, was suspected. Endascopic polypectamy was performed in order to establish the diagnosis. The excisional specimen measured 12×12×10mm, and was covered with normal mucosa. Histological examination of the specimen showed lymphoid follicular hyperplasia with germinal centers mainly in the submucosa. No atypical lymphocytes were found. Immunohistological staining did not show any monoclonality in the lymphocytes forming theprotrusion. A dignosis of benign lymphoid follicular polyp was then established. This isarare disease in Japan, and in this report, we discussed this case and some studies in theliterature.
