[Malignant thymoma. Apropos of 10 cases]

The current article proposes a review of the literature on the malignant thymoma, from 10 cases treated in the Henri Becquerel's Centre in Rouen. The middle age varies between 45 and 55 years, the sex ratio is 1/1. The principal histological type is the lympho-epithelial, then épithelial and lymphocytic. The 5-year survival varies between 45 and 75%. The most important factor of prognosis is the invading's degree. The initial treatment is surgical with an excision as complete as possible, then X-ray treatment. The utilization of the chemotherapy is still undecided, the cisplatin is the most effective product.
