(Concluded from page 404) A case of Sjogren's syndrome in a Coloured female aged 50 is descriptionbed. The rarity of the syndrome is stressed. The case is unusual in that it is associated with a lung lesion. In addition, the patient had pyelonephritis, associated with nephrocalcinosis. It is suggested that the calcification is calyceal and not pyramidal (or tubular). The pathogenesis of nephrocalcinosis is discussed.
