[Post-amoxicilline neutropenic rectitis in an immunocompetent patient: a case report].

We report a 38-year-old immunocompetent patient who presented with a neutropenic rectitis after a treatment by amoxicillin for nasopharyngitis. Neutropenic colitis is a digestive wall inflammation, preferentially localized in the ileo-caecal area and the right colon, which leads to necrosis and sepsis, and usually occurs in neutropenic patients treated by chemotherapy with an incidence of 6%. It is a serious and often lethal disease. The treatment is supportive, and surgery is limited to the occurrence of complications (perforation, bleeding). Neutropenic colitis occurring in a rectal location after antibiotic therapy in an immunocompetent patient has been rarely described.
