Efficacy of long-term ultrasonography in follow-up of patients with papillary thyroid carcinoma: a case of neck metastasis developed 19 years following primary treatment

Abstract

The cases of relapse in papillary thyroid cancer patients who were initially considered low-risk and for many years were without signs of the disease are extremely rare, but exist. This is supported by the clinical case of a patient who underwent a total thyroidectomy due to papillary thyroid cancer and 19 years later metastasis with extracapsular spreading in a presumed thyroid place was revealed. Due to such cases, the importance of long-term ultrasound monitoring is emphasized.
