[Biopsy of the minor salivary glands in Sjögren's syndrome]

Twenty subjects, 17 females and 3 males, mean age 55.9, with Sjögren's syndrome (13 cases: classical or secondary form--7 cases: sicca syndrome) were submitted to biopsy of the minor salivary glands of the lower lip. The histopathological findings from the salivary glands and the clinical aspects of each patient were separately evaluated, in order to find a possible connection between the degree of glandular impairment and the severity of the disease. As a result of their findings, the authors conclude that the biopsy of the salivary glands, while constituting an important element for diagnosis, cannot be considered a determining factor for making a prognosis, or for therapy, because of the extreme polymorphism in the histopathological findings, and for the relative nature of the respondents with the severity of the clinical aspects.
