Cutaneous metastasis from medullary carcinoma of thyroid gland.

Metastases to the skin from thyroid carcinoma, especially the medullary type, are rare and known to occur in the setting of disseminated neoplastic disease. A case of cutaneous metastasis from a medullary thyroid carcinoma with other local and distant metastatic lesions is reported. A 29 year old man presented with painful skin lesions on the neck and upper chest. He had been examined for a neck mass that after total thyroid and modified radical neck dissection was diagnosed as medullary thyroid carcinoma. Thyroid carcinoma metastatic to the skin is rare and most of the reported cases have been associated with follicular carcinomas.
