  • Abstract
  • Look Inside

 A 57-year-old female was admitted to our hospital, complaining of rectal bleeding. Double contrast study of rectum showed the hemispheric polypoid lesion with smooth surface. Endoscopy showed a submucosal tumor with central depression in the rectum. The biopsy specimen taken from this lesion showed proliferation of normal lymphocytes with forming lymph follicles. Thus, this lesion was diagnosed as benign lymphoid polyp of the rectum. Endoscopic ultrasonography of this lesion showed well-demarcated hypoechoic area in the second and third layers.

 Transanal local resection was performed. Histologically, the polypoid lesion was composed of proliferation of lymph follicles with germinal centers in the submucosal layer in the resected specimen. Fifteen cases of benign lymphoid polyp of the rectum have been reported in Japan.
