le·thal mid·line gran·u·lo·ma

1. destruction of the nasal septum, hard palate, lateral nasal walls, paranasal sinuses, skin of the face, orbit and nasopharynx by an inflammatory infiltrate with atypical lymphocytic and histiocytic cells; a form of lymphoma in most cases. 2. obsolete term for polymorphic reticulosis.

lethal midline granuloma

The term is now retired and of historic interest. Lethal midline granuloma was best considered a clinical syndrome rather than a specific histologic lesion, and described as a destructive lesion of the upper respiratory tract—nose, nasopharynx, palate and midface. It was either idiopathic or secondary to lymphoma, malignant histiocytosis or Wegener’s granulomatosis. Many of the lesions formerly designated as lethal midline granoma would now be called angiocentric lymphoma and angiocentric immunoproliferative lesions.
