[Malignant nasal granuloma in a 12 year old boy (author's transl)].

Granuloma gangraenescens is placed between Wegener's granulomatosis and reticulum cell sarcoma. It is very difficult to diagnose due to absence of early symptoms as in this reported case, which was diagnosed histologically and which temporally responded to steroids and Imurek. Change histologically to a reticulum cell sarcoma has not been proven.
