A Man With Sicca Symptoms and Bilateral Parotid Enlargement

摘要

A 50-year-old otherwise healthy man presented with a three month history of dry mouth, dry eyes, and a recent bilateral painless enlargement of his parotid gland. He denied fatigue, fever, cough, wheeze, or night sweats. Physical examination was normal except for bilateral parotid swelling and severe dryness of the oral mucosa. There was no evidence of lymphadenopathy. A complete blood count, liver function tests, chemistry panel, and urinalysis were normal except for an erythrocyte sedimentation rate (ESR) of 33 mm/h. Antinuclear antibodies, anti-Ro (SSA), anti-La (SSB), rheumatoid factor, Rose-Ragan and antineu-trophilic cytoplasmic antibodies (ANCA) were negative. Laboratory evaluation for HIV and hepatitis B and C virus were negative.
