Pathology-Proven Inguinal Node Metastasis from Papillary Thyroid Cancer in a Male without Disease below the Diaphragm.

We present the case of a 55-year-old white male with biopsy-proven left inguinal lymph node metastasis from differentiated papillary thyroid cancer. Inguinal node metastasis from papillary thyroid cancer is an extremely rare finding. The case demonstrates that papillary thyroid cancer is capable of metastasis presumably through the lymphatic system to unexpected locations.
