Renal Cell Carcinoma with Thyroid and Bilateral Adrenal Gland Metastases

Abstract

Renal cell carcinoma is the most common type of malignant kidney disease, representing more than 90% of cases. It frequently metastasizes to the lungs, bones, liver and brain. Thyroid and adrenal metastases are rare. In this case report, we present a 64-year-old man with renal cell carcinoma who developed bilateral adrenal metastases three years after right radical nephrectomy and thyroid metastases five years later. Renal cell carcinoma has a high metastasis rate and requires careful follow-up. The increasing use of non-invasive imaging modalities has increased the detection rates of rare adrenal and thyroid metastases. Due to the rarity of such cases, standard treatment protocols are not well defined, emphasizing the need for careful follow-up even years after surgery.
