Radiotherapy-Associated Paraneoplastic Pemphigus and Its Complications in a Patient with Nasopharyngeal Carcinoma

Abstract

Paraneoplastic pemphigus arising in association with non-haematological cancers is extremely rare, and there are no reported cases of a patient developing this in the setting of nasopharyngeal carcinoma and only 2 reported cases of patients developing this in response to radiotherapy.
