Necrosis of thyroid nodules after fine needle aspiration.
In a series of 200 fine needle aspirations (FNA) of the thyroid, necrosis around the needle tract was histologically evident in 2 of 30 cases with surgical follow-up. In one case of a differentiated thyroid carcinoma, necrosis with involution of the nodule was the dominant finding. This suggests that FNA can induce necrosis and apparent clinical regression of thyroid neoplasms. We believe, however, that a positive cytologic diagnosis coupled with a clinical suspicion of neoplasm should lead to surgical intervention, despite clinical regression following FNA.
