Thymoma associated with myasthenia gravis and Sjögren syndrome.

Thymoma is the most common neoplasm of the anterior mediastinum but thymoma with Sjögren syndrome (SS) is rare. Sjögren syndrome is a systemic autoimmune inflammatory disorder. It is characterized by lymphocyte-mediated destruction of exocrine glands, which leads to absent glandular secretion. Here, we present the case of a 63-year-old man with thymoma and concurrent myasthenia gravis and SS, who achieved remission after thymectomy.
