Case Discussion

About 90% of cancers that develop in the thymus are thymomas. These tumors originate in the epitelial cells lining the thyme and often grow slowly, rarely spread beyond the thymus itself. However, some thymomas are more aggressive and can spread to surronding tissues and organs (lung and pleura). Thymoma is a tumor that affects mainly in the age group between 40 and 60 years, with no significant differences between men and women.
