[A rare case of maxillary sinus sarcoidosis (author's transl)].

We describe a 36 year old man who underwent three Caldwell-Luc operations during a five year period. Following the first operation, a persistent induration of the cheek was noted, and was found to be sarcoidosis histologically after the third operation. Since sarcoidosis is uncommonly found in the region of the maxillary sinus, its occurrence might be considered due to either irritation (such as seen with foreign body reaction) or result from the preceding surgical trauma. The etiology, symptomatology, and therapy of sarcoidosis is surveyed.
