Thymoma and T-Lymphoblastic Lymphomas (T-LBL) are primary mediastinal neoplasms that can have similar clinical presentations and overlapping histological features. Because of immature lymphocytes associated with thymoma, it may resemble T-lymphoblastic lymphomas. In this present case report, a 20-year-old male patient with recurrent unresectable thymoma has received definitive chemoradiation therapy. Significant reduction of gross tumour volume was observed while patient underwent weekly image verification before radiotherapy at the end of fourth week, causing the suspicious about the possibility of a highly radiosensitive tumour in mediastinum like lymphoma or extragonadal germ cell tumour. External review of immumohistochemistry features were suggestive of T-lymphoblastic lymphomas.
