title: Primary Sjögren's syndrome complicated by sarcoidosis.
abstract: Sjögren's syndrome and sarcoidosis share several common features, such as keratoconjunctivitis sicca, swelling of parotid glands, lung involvement, cutaneous anergy, T cell-mediated immunodeficiency, an increased CD4+/CD8+ lymphocyte ratio, and association with the human leucocyte antigen (HLA)-B 8 and DR 3 haplotypes. However, only five patients with primary Sjögren's syndrome and sarcoidosis have been previously reported in the English language literature. The rare case of a 49-year-old Japanese woman with primary Sjögren's syndrome complicated by sarcoidosis is described. The serum angiotensin-converting enzyme level was increased, and histological examination of lung and skin biopsies revealed noncaseating granulomas, indicating that her primary Sjögren's syndrome was complicated by sarcoidosis.
