[Manifestations of paranasal sinus malignant lymphoma (author's transl)].

Malignant lymphomas rarely arise initially in the paranasal sinuses, although these may become involved at a later stage of the disease. Such cases have rarely been reported because the paranasal sinuses are seldom subjected to routine postmortem examination, and the clinical signs often resemble those of suppurative sinusitis. The present paper reports 3 patients in whom the paranasal sinuses were affected by a malignant lymphoma (chronic lymphatic leukaemia). The histological findings are illustrated and the pathogenesis discussed.
