Thymoma is linked with myasthenia gravis and other autoimmune diseases. Signs and symptoms of thymoma and thymic carcinoma include a cough and chest pain. Tests that examine the thymus are used to detect (find) thymoma or thymic carcinoma. Thymoma and thymic carcinoma are usually diagnosed, staged, and treated during surgery.

Thymoma is the most common primary tumor of anterior mediastinum and accounts for 20% of all mediastinal tumors. Although it can occur at any age, most patients are older than 40 years at the presentation. They are usually located anteriorly to the aortic arch but can occur in cardiophrenic angle.

Noninvasive thymoma manifests as a completely encapsulated tumor without microscopic evidence of growth outside the tumor capsule, whereas invasive thymoma demonstrates microscopic evidence of such growth, occasionally showing pleural implants and, rarely, hematogenous and lymphatic metastasis ( , 5 ). A thymoma is a tumor originating from the epithelial cells of the thymus that is considered a rare malignancy. Thymomas are frequently associated with the neuromuscular disorder such as myasthenia gravis; thymoma is found in 20% of patients with myasthenia gravis.

Harvestcandle | 931-241 Phone Macroscopically thymic tumors are of variable shape, with thymomas typically rounded with a bosselated outer surface. The cut surface is tan or grey-pink with lobulated architecture, separated by fibrous septae 11. Both non-invasive and invasive thymomas may appear to have an intact capsule, and microscopic examination is required. Thymoma is the most common primary tumor of anterior mediastinum and accounts for 20% of all mediastinal tumors.
