| Abstract | Paraneoplastic pemphigus is a relatively rare but highly significant acquired mucocutaneous disorder. The condition typically presents in patients with previously diagnosed lymphoreticular disease, primarily malignancies (non-Hodgkin's lymphoma; chronic lymphocytic leukemia). Multiple sites of involvement are common, with the skin affected by a polymorphous eruption that includes lichenoid plaques as well as bullae. The oral lesions occur in all cases and present as painful widespread shallow ulcers with hemorrhagic crusting of the lips. Conjunctival involvement is also seen and may result in scarring. Pulmonary lesions are an ominous sign. Histopathologically, intraepithelial and subepithelial clefting associated with interface dermatitis are seen. A variety of autoantibodies directed against desmoplakins and desmogleins can be identified with immunoprecipitation studies. Treatment with immunosuppressive agents may result in some resolution of the disease, but the prognosis for paraneoplastic pemphigus is considered to be poor. |
