Abstract

Cutaneous metastases from follicular thyroid carcinoma are extremely rare. A 59-year-old woman presented with a 1 month history of a slowly enlarging scalp nodule. Ten years earlier, the patient had been received total thyroidectomy for anterior neck mass, and diagnosed as poorly differentiated follicular thyroid carcinoma. The patient had developed pulmonary metastases 4 years after the initial surgery and concurrent chemotherapy. A biopsy from the scalp nodule showed an intradermal tumor composed of mostly thyroid follicular structures with colloid material. The tumor cells were monomorphic with scant pale cytoplasm and uniform nuclei, and stained positive for thyroid transcription factor-1 and thyroglobulin. We report a cutaneous metastasis from the follicular thyroid carcinoma as a rare case.
