Histiocytic malignant lymphoma arising in the midfacial soft tissues

Histiocytic malignant lymphoma arising in the midfacial soft tissues represents an uncommon clinical disorder. We report our experiences with a 63-year-old man with nasal obstruction secondary to a nasal septal mass that developed four weeks after a routine septoplasty. Final pathologic appearance after multiple biopsies was consistent with histiocytic malignant lymphoma. Clinical features, histopathologic findings, therapy, and prognosis are discussed.
