What is paraneoplastic pemphigus?
The pemphigus family are rare autoimmune blistering diseases affecting skin and/or mucous membranes. Paraneoplastic conditions occur in association with malignancies (cancer). Paraneoplastic pemphigus is characterised by painful blisters and denuded areas of the mouth, lips, oesophagus and skin. It is the least common but most serious form of pemphigus, particularly considering the presence of the underlying cancer.
