A case of multiple thymoma associated with oral lichen planus and hypogammaglobulinemia

Abstract

A 71-year-old woman being treated for oral lichen planus with hypogammaglobulinemia showed mass lesions in the anterior mediastinum. On chest CT, an independent tumor in each lobe of the thymus was detected. The left-sided lesion was pathologically diagnosed as a thymoma by CT-guided needle biopsy, and thymothymectomy revealed the two tumors to be type A and AB multiple thymoma. She has experienced no recurrence of the thymoma, and the oral pain due to lichen planus had partially resolved while her hypogammaglobulinemia had not improved at 13 months after surgery.
