[Adult recurrent sialadenitis of parotid gland and Sjogren's syndrome].

This paper presents clinical, laboratory and sialographic studies on 22 patients with recurrent sialadenitis of parotid glands in adults (RSPA), 103 sjögren's syndrome (SS) cases, and particularly a long term (2 approximately 24 years, mean 10 years) follow-up studies on 22 patients with RSPA. Twelve out of 22 RSPA patients developed SS. These patients had recurrent parotid swelling for 1.5 approximately 14 years (mean 5.2 years) before xerostomia and keratoconjunctivitis sicca presented. Ten of the 22 RSPA patients did not develop SS, of them 10 experienced recurrent parotitis from childhood to adulthood, and the disease underwent remission in 7 of them. It is suggested to classify RSPA patients without any history of parotid swellings in childhood tentatively as subclinical SS (SCSS).
