Thymoma associated with hypogammaglobulinemia and profound susceptibility to recurrent and serious infections was first reported by Good in 1954, after whom it was named as Good's syndrome. Chronic diarrhea associated with thymoma is almost always seen in patients with hypogammaglobulinemia.
An elderly man with thymoma, myasthenia gravis, and hypogammaglobulinemia developed profuse watery diarrhea. Infusions of gamma-globulin caused the diarrhea to resolve. The patient succumbed to fulminant bronchopneumonia. At necropsy he was found to have widespread cytomegalovirus infection with

A 62-year-old woman was admitted to our hospital because of diarrhea and melena. Thymectomy for thymoma with myasthenia gravis was carried out on this patient four years ago. Barium enema revealed four tumor shadows in the ascending and transverse colon. Multiple colon cancer was diagnosed and
