Metastatic Hürthle cell carcinoma of the thyroid presenting as ulcerated scrotum nodules.

Cutaneous metastasis from Hürthle cell carcinoma of the thyroid is an extremely rare phenomenon. As far as we can determine, there has been only a single case documented. Our patient, a 68-year old man with a history of Hürthle cell carcinoma of the thyroid, had cutaneous nodules in the scrotum and right chin. Histologic and immunohistochemical examinations confirmed the diagnosis of metastatic Hürthle cell carcinoma of the thyroid. To the best of our knowledge, this is the first reported case of scrotal skin metastasis. This case emphasizes the importance of thorough clinicopathologic correlation for any patient with a malignant scrotal cutaneous neoplasm with Hürthle cell or oncocytic differentiation.
