title: [Midfacial necrosis: a propos of 2 cases and review of the literature].
abstract: Two patients presenting the clinical characteristics of the "Lethal Midline Granuloma" are discussed. In the first case, the autopsy allowed the final diagnosis of a histiocytic medullary reticulosis (Robb-Smith). For the second patient the late evolution and the final biopsy gave the diagnosis of malignant reticulosis without further detail. These two cases prove that for a midface necrosis no final diagnosis can be obtained without an extensive clinical examination and autopsy material. There are numerous arguments to consider the "Lethal Midline Granuloma" as a clinical term which can cover several pathological entities. A classification is proposed.
