Eosinophilic granuloma of sternum. Report of one case.

A rare case of solitary eosinophilic granuloma of the sternum in a 5-year-old boy is reported. He presented anterior chest pain and a nodular, somewhat tender mass over the sternum. Chest x-ray, tomography, CT scanning of the sternum and total body Gallium scanning revealed an isolated lytic lesion 5 cm below the sternal angle. An excisional biopsy of the mass showed the typical histologic appearance of eosinophilic granuloma. An isolated eosinophilic granuloma of sternum is rarely reported in the English literature. The differential diagnosis of sternal tumors and a review of eosinophilic granuloma of sternum is discussed.
