Two Elderly Patients with Sarcoidosis and Sjögren's Syndrome

Two elderly patients with sarcoidosis complicated with Sjögren's syndrome are described. Case 1: A 70-year-old woman was admitted due to dry eyes. Histological examination of a minor salivary gland specimen revealed lymphocytic infiltration, which was compatible with Sjögren's syndrome. Because uveitis was demonstrated, transbronchial lung biopsy (TBLB) was performed, to confirm a diagnosis of lung sarcoidosis. Histological examination of TBLB showed non-caseating granulomas compatible with sarcoidosis. Case 2: A 70-year-old woman was admitted due to dyspnea on exercise and blurred vision. Two years previously, Sjö gren's syndrome was diagnosed because of a positive Shirmer test and positive SS-A antibody. Result of ophthalmic examination were compatible with uveitis. Histological examination of TBLB showed non-caseating granulomas compatible with sarcoidosis. Certain similarities between sarcoidosis and Sjögren's syndrome in terms of immunological aspects have attracted attenion. In the present manuscript, a possible relationship between the two diseases as well as the characteristics of elderly sarcoidosis are discussed.
