[A case of "midline granuloma" in a 29-year-old patient].

The term "(lethal) midline granuloma" originates from the disease's clinical presentations, including various granulomatous, inflammatory and destructive changes as well as necrosis of the midface. The present paper discusses the case of a 29-year-old woman with a midline granuloma involving the left palatal cleft and affecting the nose and naso-maxillary sinus. In terms of the currently available literature the difficulties are shown in diagnosing "midline granuloma" from other possible diseases using histomorphological criteria. Various therapies are discussed, including those used in the present case.
