In the vulvar pathology surgery unit we have come across 3 patients with Sjögren's syndrome. Two of them also now show the presence of vulvar carcinoma, and one of them shows the presence of vulvar dystrophy with dysplasia. This has induced us to consider the possible connections between the 2 pathologies. All 3 of the patients, at different times and in different periods have been treated with steroids for the original disorder. The connections between the 2 affections are presumably to be found in the possible autoimmunitary genesis of the original disease and in the concomitant use of steroids.
