Eosinophilic Granuloma of the Skull Vault: A Case Report.

Alessia Imperato, Domenico Gerardo Iacopino, Francesca Graziano, Carlo Gul

Background: Eosinophilic granuloma is the benign form of Langerhans cell histiocytosis, a rare proliferative disorder. Skull osteolytic lesions are quite frequently encountered.

Case report: We report the case of a 16 year old boy who was admitted to our Department with a painful swelling left frontal mass. A diagnosis of eosinophilic granuloma was presumed on the basis of the neuroradiological findings. Surgical removal of the lesion was achieved and the bone defect reconstructed by autologous fibrin glue and a titanium mesh. Histopathology confirmed the diagnosis.

Conclusion: Although uncommon, eosinophilic granuloma should be considered in the differential diagnosis in case of an osteolytic calvarial lesion.
