ABSTRACT A 36-year-old woman complained of cough and high fever. Computed tomographic scans demonstrated a mediastinal mass. A couple
of months later, she developed dryness in her eyes and mouth. Biopsy of the lip confirmed the diagnosis of Sjögren’s syndrome.
She underwent thymo-thymomectomy. Pathological findings of the mass revealed thymoma. At two months after surgery, she developed
ptosis and dysphagia that were compatible with myasthenia gravis. The clinical symptoms were adequately controlled with prednisolone.
At eleven months after surgery, she presented with severe anemia, which led to the diagnosis of pure red cell aplasia. The
following treatment with cyclosporin caused hemoglobin concentration to rise. However, she continues to suffer from dryness
of her eyes and mouth. The case is the first to be reported with Sjögren’s syndrome and the triad of thymoma, myasthenia gravis
and pure red cell aplasia, and is compared with previously reported cases of the three conditions.
