[Neutropenic enterocolitis].

A 58-year old patient with metastasizing squamous cell carcinoma of the left lung developed fever, diffuse abdominal pain and profuse diarrhea while treated with paclitaxel and radiation therapy. A sigmoidoscopy was performed to exclude pseudomembranous colitis but showed multiple mucosal petechiae. Histologic examination disclosed neutropenic colitis. Conservative treatment was successful.
