“Nodule in Nodule” on Thyroid Ultrasonography: Possibility of Follicular Carcinoma Transformed from Benign Thyroid Tumor

Conclusion: A small number of patients with follicular carcinomas or follicular neoplasms may present with a “nodule in nodule” appearance on ultrasonography. It was suggested a long time ago that follicular carcinomas may develop from benign thyroid tumors. The fact that follicular carcinomas appear within benign tumors may be evidence of thyroid tumorigenesis.Eur Thyroid J
