[A case of eosinophilic granuloma of the frontal bone (author's transl)].

Osteolytic focusses in the frontal bone are frequently considered as complication of the frontal sinus or as metastatic process. It is necessary to mention the eosinophilic granuloma of the bone, which is not quite seldom in this area. An operation must be done in most cases to obtain the histology and, in the same way, as treatment.
