Answer

Controversy exists over the efficacy of fine-needle aspiration (FNA). FNA has been reported by some to be beneficial in making the diagnosis of a thymoma. Performing a core biopsy in conjunction with FNA is a modality that can increase the accuracy with which thymomas can be differentiated from other neoplasms, such as lymphomas and germ cell tumors.
