Abstract
Background: Thymoma is a rare neoplasm, which may be associated with autoimmune disorders, the occurrence of hyperthyroidism in the patients with thymoma is rare. Clinical presentation: Here we present an extremely rare case of a 56-year-old female patient who was discovered to have malignant thymoma with associated myasthenia gravis and hyperthyroidism due to toxic multinodular goiter. Our patient started to complain of difficulty breathing and swallowing, Chest CT scan was done and revealed an anterior mediastinal mass, measures about 4.1 × 3.1 × 2.2 cm with enlarged lymph node mostly representing thymoma. Complete thymectomy was performed via uniportal video-assisted thoracoscopic surgery, and the patient's postoperative recovery was uneventful. Microscopic histopathology findings corresponded to thymoma type B1. Conclusion: The coexistence of thymoma, MG and toxic multinodular goiter is extremely rare. MG should always be suspected in a patient with thymoma. VATS thymectomy has been increasingly used to treat thymoma as it has several advantages over open surgery.
