Resolution of paraneoplastic skin lesion after thymectomy

Abstract

Thymoma is the most common primary mediastinal neoplasm. It is well known to have a strong association with autoimmune diseases, but associated cutaneous disorders are considerably rare presentation of thymoma as paraneoplastic manifestation. Thymectomy is an optional treatment in some autoimmune diseases such as myasthenia gravis. We describe a 51-year-old male with a history of thymoma for 6 years accompanied by generalized severe purpuric rash, which was completely resolved after thymectomy.
