A Case of Eosinophilic Granuloma of the Temporal Bone / 대한이비인후과학회지

ABSTRACT

Eosinophilic granuloma is characterized by osteolytic skeletal lesions which are infiltrated by abnormal histiocyte, eosinophil and giant cells. Eosinophilic granuloma has been described as Histiocytosis X in 1953 by Lichtenstein. Eosinophilic granuloma generally implies osseous disease alone. Single solitary site of the bone is typically affected, although multifocal involvement can occur. This lesion involves long or flat bone. The skull bone, especially the temporal or frontal bone are the most frequent site of the body for involvement of this lesion. Prognosis is relatively favorable. We report, with a review of relevant literature, a case of eosinophilic granuloma of the temporal bone which was treated surgically in a 5-year-old male.
