title: Lichen planus and Sjögren-type sicca syndrome in a patient with chronic hepatitis C.
abstract: We report a 54-year-old Japanese male with lichen planus and Sjögren-type sicca syndrome, accompanied by the latent complication of chronic hepatitis C. The patient first showed erythematous and erosive lesions with white irregular striae in the buccal mucous membrane, and blepharitis and hyperemia of conjunctiva in his eyes. He later had two small erosions on the glans penis, and flat-topped violaceous papules on the dorsa manus and nape. A biopsy specimen of the lower lip lesion demonstrated a lichenoid tissue reaction at the basement membrane zone, and lymphocytic focal accumulations in the salivary glands. Immunohistochemical study of this specimen revealed CD45RO- (T) cells associated with the expression of HLA-DR antigens predominantly in both the lichenoid tissue reaction and the lymphocytic sialadenitis. Objective keratoconjunctivitis sicca was confirmed by the Schirmer and Rose-Bengal tests. Anti-DNA antibody was positive; however anti-SS-A, and anti-SS-B antibodies were negative. Increased levels of transaminase enzymes, TTT, ZTT, and IgG were observed in first laboratory examinations; thereafter, antihepatitis C virus (HCV) antibodies and HCV-RNA were detected. The high serum amylase level, in which salivary amylase predominated, was normalized by etretinate therapy in parallel with the clinical improvement of the oral LP lesions. Our case is considered to support the hypothesis that an etiologic association may be present among lichen planus, Sjögren's syndrome, and chronic hepatitis C.
