[Craniofacial granulomatous lesions].

Granulomatous lesions of the cranio-facial area are frequent and various in their nature: lymphohistiocytic with or without eosinophils, tuberculoid-like with epithelioid and giant cells, or sometimes made essentially of giant cells. Their etiology can be known or easy to find: foreign body granuloma, sarcoidosis, leprosy, rhinoscleroma, fungal diseases especially zygomycosis and rhinosporidiosis, parasitic diseases. The lethal midline granuloma is a clinical entity characterized by its necrotic and relentlessly progressive destructive presentation. After elimination of a malignant process, especially lymphoid, and of a Wegener's granulomatosis the diagnosis will be "idiopathic midline non-healing granuloma". Some of them will stay located at the facial area; others will disseminate as a malignant disease. Central giant cell granuloma and histiocytosis X, especially eosinophilic granuloma, are two other varieties of granuloma, different of the former granulomatous infiltrates by their clinical presentation and their evolution.
