The authors report on three cases of so-called midline granuloma submitted to clinicopathologic and immunophenotype studies. The histopathologic features detected were necrosis, vasculitis and an atypical lymphohistiocytic infiltrate. Immunophenotype studies using monoclonal antibodies showed evidence leading to the diagnosis of nasal T cell lymphoma or lymphomatoid granulomatosis. Two of the patients with the presence of progressive or large cells died within 24 months, indicating that the size of the atypical lymphoid cells may be of prognostic significance.
