title: Lupus erythematosus with oral and perianal mucous membrane involvement.
abstract: A 57-year-old man with lupus erythematosus (LE) had mucous membrane involvement that included the oral and perianal mucosa. Microscopic findings of the oral and perianal mucous membrane lesions were not diagnostic of LE, but immunofluorescent microscopy of biopsy specimens of the lip and perianal mucosa showed the lupus band.
