Solitary eosinophilic granuloma is a rather benign and localized form of Langerhans's cell histiocytosis. Definitive diagnosis is made by histopathology including immunohistochemical detection of S-100, HLA-DR and CD1a antigens. We report the case of a twenty-five year old boy presented with headache and orbit's pain. A CT scan showed a left supero-lateral orbital mass with evidence of bone erosion. The different options of treatment are discussed and the literature is reviewed.
El granuloma solitario eosinófilo es un tumor normalmente benigno y es una forma localizada de la hisitiocitosis de las celulas de Langerhans. La diagnosis definitiva viene de un estudio histopaológico incluida la búsqueda con métodos inmunohistoquímicos de S-100, HLA-DR y de los antígenos CD1a. Proponemos el caso de un joven de venticinco años que presentaba dolor de cabeza y dolor de una órbita. Una TAC muestra una masa en sede orbital supra-lateral izquierda con una evidencia de erosión del hueso. Se discuten las diferentes elecciones de tratamiento y se revisa la bibliografia.
