Key Words: Thymolipoma Myasthenia gravis
A 25-year-old female patient with myasthenia gravis underwent resection of a giant mass located in the anterior mediastinum that measured 34x18x7 cm and weighed 1,780 g (Fig. 1)
. Histologically, the tumor proved to be a thymolipoma (Fig. 2)
. The association of myasthenia gravis with giant thymolipoma is rare. Myasthenic symptoms improved significantly after surgery.
