Prostate Adenocarcinoma Metastasis and Papillary Thyroid Carcinoma: A Case Report of Coexisting Thyroid Tumors
Abstract
Metastasis to the thyroid is a relatively unusual clinical entity with prostatic carcinoma metastasizing to the thyroid rarely reported in the literature. We present a case of an 87 year old male who underwent total thyroidectomy for a 2 cm papillary thyroid carcinoma with a second neighboring hypercellular focus suggestive of follicular variant papillary carcinoma. Immunohistochemical staining was negative for thyroglobulin and positive for PSA, indicating a metastatic focus of prostate cancer. We report a case of a patient with prostate cancer metastasis to the thyroid near a coexisting papillary thyroid carcinoma.
