Abstract
Langerhans cell histiocytosis is rare and can be categorized into three forms on the basis and extent of organ involvement: eosinophilic granuloma, Hand-Schüller-Christian disease, and Letterer Siewe disease. We present a 30-year-old patient with an isolated eosinophilic granuloma arising from the supratemporal orbital bone and manifesting as a space-occupying orbital lesion. Langerhans cell histiocytosis should be considered in the differential diagnosis of orbital tumors in both children and adults.
