Therapy of paraneoplastic pemphigus with Rituximab: A case report.

We report a case of 39‐year‐old female patient with paraneoplastic pemphigus (PNP) associated with thymoma treated with rituximab plus corticosteroids and methotrexate. After rituximab therapy for 8 weeks, oral ulcerations had cured, lesions on the trunk and limbs improved. Rituximab may be useful for PNP therapy, but further studies are necessary to confirm this hypothesis. [ABSTRACT FROM AUTHOR]
