متن کامل[Cases of lethal midline granuloma (polymorphic reticulosis) at our department in a recent 10-year period].
We had 18 patients (15 males and 3 females) with lethal midline granuloma (polymorphic reticulosis) in the period from 1981 to 1990. This number was about 5.6% of the total number of patients with malignant head and neck tumors that we encountered during this period.

Evidence is provided that such changes represent a malignant neoplasm of histiocytic lymphoma type. Local invas...
