Cat scratch colon. A new ethiopathogenic possibility.

Our case describes an 80-year-old female who presented an asymptomatic lower intestinal bleeding after depositions without hemodynamic repercussion, rectal tenesmus or abdominal pain. She relates alternating constipation and diarrhea in the last twenty years without recent changes. Colonoscopy (done under sedation): Hemorrhoids grade III/IV. Pancolonic diverticulosis. In the cecum mucosa, numerous lineal erosions, 3 to 4 cm long, with inflammatory appearance were found. Ileocecal valve and the fifteen last centimeters of ileum displayed no pathological findings or traces of blood. Biopsies of colonic mucosa did not show any sign of inflammation.
