title: Eosinophilic granuloma: Presenting as a draining fistula.
abstract: A case report of an orbital eosinophilic granuloma presenting as a fistula in a 15-year-old boy is presented. The patient had a history of a painful right upper eyelid swelling which required drainage and was considered as an abscess. An increase in swelling occurred and a small fistula appeared in the area subsequently. Computed tomography scan revealed a large soft tissue lesion in right superolateral orbit having intracranial extradural extension with destruction of bony orbital margin. Fine needle aspiration biopsy of the lesion revealed eosinophilic granuloma. A complete excision of the lesion was performed by a brow incision and histopathological examination of the excised specimen confirmed diagnosis. Although upper eyelid area eosinophilic granuloma is known to occur, its presentation as a fistula is not known.
