[Chronic increase of amylase in primary sicca syndrome].

Pancreatitis had been erroneously diagnosed in a 50-year-old female patient with primary sicca syndrome with chronic salivary-gland-caused increase of amylase of 5 years' standing. Differentiation of amylase into isoenzymes showed clearly increased salivary amylase with normal pancreatic amylase. Little is known on the increase of amylase in Sjögren's syndrome. Unresolved increase of amylase of non-pancreatic origin should thus also lead to consideration of sicca syndrome.
