A thymoma is a tumor originating from the epithelial cells of the thymus that is considered a rare neoplasm. [1] Thymomas are frequently associated with neuromuscular disorders such as myasthenia gravis ; [ 2 ] thymoma is found in 20% of patients with myasthenia gravis. [ 3 ]
Thymic carcinoma, or type C thymoma, is a malignancy of the thymus. It is a rare cancer that is often diagnosed at advanced stages. Recurrence following treatment is common, and thymic carcinoma is associated with a poor prognosis .
A dad, 45, had what seemed like a pinched nerve. It was a sign of a cancerous thymoma. Chest pain, shortness of breath were signs of his thymoma.
Thymoma with immunodeficiency (also known as "Good syndrome") is a rare disorder that occurs in adults in whom hypogammaglobulinemia, deficient cell-mediated immunity, and thymoma (usually benign) may develop almost simultaneously. [1]: 82 [2] Most reported cases are in Europe, though it occurs globally. [3]
Thymoma is a common neoplasm arising from the thymus, the primary lymphoid organ where T cells become educated to distinguish "self" from "non self". In the setting of thymoma, abnormal thymic education occurs as a result of subtle differences in antigen processing. In TAMA these differences result in autoreactive T cells escaping from the thymus.
Tonofibrils seen under electron microscopy can differentiate thymoma from other tumors such as carcinoid, Hodgkin's, and seminoma. Patients are usually asymptomatic but can present with myasthenia gravis-related symptoms, substernal pain, dyspnea, or cough. Invasive tumors can produce compression effects such as superior vena cava syndrome.

Thymoma-associated multiorgan autoimmunity can occur in people with thymoma. In this condition, the T cells developed in the thymus are directed against the tissues of the body. This is because the malignant thymus is incapable of appropriately educating developing thymocytes to eliminate self-reactive T cells.
