Etiology of myasthenia gravis

Reason 1: thymus hyperplasia: the main pathological manifestations are medulla enlargement, lymphocyte proliferation, accompanied by germinal center formation and branching hyperplasia of capillaries, endothelial cell swelling. Under the electron microscope, the lymphocytes formed abundant cytoplasmic processes and crossed each other to form interdigital structures.

Reason 2: thymoma: from epithelial cells, is the most common tumor in the anterior mediastinum, thymoma often accompanied by paraneoplastic syndrome, in which myasthenia gravis is the most common. The pathological manifestations of thymoma are complex. The volume of thymoma varies. The color of thymoma is dark brown or grayish red. The shape of thymoma is round, oval or irregular. The surface is often nodular. In benign cases, the capsule is complete, and there is no adhesion with the surrounding. In malignant cases, the capsule is not complete, and the surface is rough, which can involve the pleura, pericardium and large blood vessels.

Cause 3: non proliferative thymus: the pathological manifestations were atrophy of cortex and medulla, involvement and replacement of adipose tissue, scattered distribution of lymphocytes, often accompanied by keratocystic thymic corpuscles, no germinal center formation.
