Spontaneous remission of myasthenia gravis in patients with thymoma. 1978

A Masaoka, and Y Monden, and Y Seike

In 42 cases of myasthenia gravis with thymoma, the tumor was removed surgically. In four of these cases, myasthenic symptoms had remitted before operation. However, in two of these four cases, myasthenic symptoms returned after operation, despite apparently total thymectomy. In two of the four cases that remitted before operation, the thymus was found to be highly involuted, without germinal centers; in another case, the thymus was found to be moderately involuted, and germinal centers were found. In the nonrelapsing cases, only the tumor itself was removed, with residual thymic tissue being left behind. The thymoma in all cases consisted of polygonal epithelial cells and lymphocytes.

D009157 Myasthenia Gravis A disorder of neuromuscular transmission characterized by fatigable weakness of cranial and skeletal muscles with elevated titers of ACETYLCHOLINE RECEPTORS or muscle-specific receptor tyrosine kinase (MuSK) autoantibodies. Clinical manifestations may include ocular muscle weakness (fluctuating, asymmetric, external ophthalmoplegia; diplopia; ptosis; and weakness of eye closure) and extraocular fatigable weakness of facial, bulbar, respiratory, and proximal limb muscles. The disease may remain limited to the ocular muscles (ocular myasthenia). THYMOMA is commonly associated with this condition.

D013945 Thymoma A neoplasm originating from thymic tissue, usually benign, and frequently encapsulated. Although it is occasionally invasive, metastases are extremely rare. It consists of any type of thymic epithelial cell as well as lymphocytes that are usually abundant. Malignant lymphomas that involve the thymus, e.g., lymphosarcoma, Hodgkin's disease (previously termed granulomatous thymoma), should not be regarded as thymoma.
