Doctor's Notes on Thymoma in Children

Thymoma is a rare tumor of the cells that cover the outside surface of the thymus; the tumor is slow growing and usually does not spread to the lymph nodes and is often found in association with other diseases (autoimmune and hormonal). Signs and symptoms may include coughing, hoarseness, fever, feeling tightness in the chest and trouble breathing and/or swallowing.

The cause of thymoma in children is unclear but may be related to other diseases that often may accompany the disease as risk factors. The following are risk factors; myasthenia gravis, polymyositis, lupus, rheumatoid arthritis, thyroiditis, Isaac syndrome (peripheral nerve disease with muscle stiffness) , pure red cell aplasia, hyperthyroidism, Addison disease and panhypopituitarism.
