Sjögren-like syndrome after drug-induced toxic epidermal necrolysis.

7 of 9 patients recovering from a drug-induced toxic epidermal necrolysis (TEN) which they had had 2 months to 4 years before had xerostomia, or keratoconjunctivitis sicca, or both. 5 patients had symptoms; 2 had severe visual impairment. In 5 cases there was lymphocytic infiltration of small salivary glands; in 2 patients this was identical to that of Sjögren syndrome. None of the patients had antinuclear antibody. TEN may occur during acute graft-versus-host disease (GVHD) and these observations are reminiscent of the sicca syndromes reported during chronic GVHD. They suggest that autoimmune mechanisms may be involved in drug-induced TEN and that Sjögren syndrome may occur as the result of a drug reaction.
