Sjögren's syndrome involving the larynx: report of a case.

Sjögren's syndrome is a presumably autoimmune disease with pathologic findings of lymphocytic infiltration of the involved structures. Although the salivary and lacrimal glands are the most commonly involved sites, extraglandular lymphoproliferation also occurs. Upper and lower respiratory tract lymphoproliferation is known, but only one case of Sjögren's disease of the larynx has been previously reported. We present a case of laryngeal involvement in which the gross pathologic appearance is different from that in the earlier case report. The otolaryngologist should consider Sjögren's disease in the differential diagnosis of diffuse laryngeal lesions.
