title: Colon carcinoma after thymectomy for myasthenia gravis: report of a case.
abstract: A 74-year-old Japanese man was admitted to our hospital with anemia, 4 years after a thymectomy for thymoma associated with myasthenia gravis. A diagnosis of sigmoid colon carcinoma was confirmed, followed by surgical resection. This case is presented to reinforce that physicians should bear in mind the possibility of extrathymic malignancies in patients with thymoma.
