Myasthenia Gravis is commonly associated with which type of tumor?

Myasthenia Gravis is an autoimmune disorder characterized by weakness and rapid fatigue of voluntary muscles, primarily due to impaired communication between nerves and muscles. Its association with thymoma is well-documented in medical literature. The thymus gland, located in the anterior mediastinum, plays a critical role in the development of the immune system, particularly in the maturation of T-cells. In individuals with Myasthenia Gravis, an abnormality or hyperplasia of the thymus is often present, leading to the development of thymomas—tumors originating from the epithelial cells of the thymus.

The presence of a thymoma in patients with Myasthenia Gravis can exacerbate the symptoms and is important for both diagnosis and management. Surgical resection of the thymoma often leads to improvement in symptoms for patients with Myasthenia Gravis. Research shows that about 10-15% of patients with this condition have thymoma, making it the most significant tumor association linked with the disorder.

Other tumor types, such as pancreatic tumors, lung cancer, and pituitary adenomas, do not have established connections with Myasthenia Gravis in terms of etiology or pathophysiology, which is why they are not
