Metastasis to the thyroid gland: a single-institution 16-year experience.

ABSTRACT:

Aims

Metastasis to the thyroid gland is a rare occurrence that may pose a diagnostic challenge. In this study, we aimed to report the clinicopathological features, immunoprofile, molecular alterations and outcome of 30 patients treated at our centre from 2003 to 2019.

Methods and results
