Change in Bowel Habit and Heme Positive Stool

Abstract

Colonoscopy revealed normal appearing mucosa in the entire colon and a 5mm sessile polyp (Figure 1) was found in the rectum on retroflexion. Random biopsies were obtained throughout the colon and the rectal polyp was completely excised. Histopathology of random colon biopsies (Figure 2) showed surface epithelial attenuation associated with increased numbers of intraepithelial and lamina propria lymphocytes (>20p/hf) consistent with lymphocytic colitis (LC).
