Abstract
Thymic carcinomas are extremely infrequent neoplasms (15% of all thymic epithelial tumors). Basaloid carcinoma is a peculiar tumor that represents no more than 2% of those infrequent thymic carcinomas. Surgical excision is the recommended treatment. As it's extremely rare, there is no evidence of the impact of different modalities of treatment. There are no reported cases that did not include surgery as part of their management. We herein present a case of an unresectable thymic basaloid carcinoma treated only with concurrent chemotherapy and radiotherapy that obtained a complete remission and free of disease after 2 years.
