Minor salivary gland punch biopsy for evaluation of Sjögren's syndrome.
Incisional biopsy of labial salivary glands has been a valuable technique for diagnosis of Sjögren's syndrome. This report describes a new technique using punch biopsies that requires fewer resources and appears to be equally effective. Fifty patients evaluated by punch biopsy all yielded adequate pieces averaging 6 glands per specimen. Two patients had transient numbness of the lip. There were no other complications. Classical findings of Sjögren's histopathology were demonstrable with these specimens. This technique is safe, less expensive, and is proposed as a reliable alternative to incisional biopsy.
