A Rare Case with Co-Occurrence of Thyroid Papillary Microcarcinoma and Multifocal Renal Cell Carcinoma Metastasis to Thyroid Gland
Keywords:Thyroid Carcinoma, Renal Cell Carcinoma, Neoplasm Metastasis
AbstractRenal cell carcinoma is a common malignancy of uroepithelial region. It may metastasize even years after nephrectomy. Â Metastatic disease of thyroid gland is rare, the most common one is being renal cell carcinoma. Unlike the cases reported in the literature as tumor to tumor metastasis, our case had co-occurrence of multifocal renal cell carcinoma metastasis in the left thyroid lobe and thyroid papillary carcinoma in the right thyroid lobe, which were diagnosed at the same time. We presented this case due to its rare occurrence.
