A Case of Scalp Metastasis from Papillary Thyroid Carcinoma / 대한이비인후과학회지

ABSTRACT

We present a case of scalp metastasis from papillary thyroid carcinoma which developed on the scalp of a 57-year-old man. The lesion was noticed at the scalp of left parietal area and a biopsy from the nodule showed mostly metastatic papillary form structures with colloidal structure. We performed immunohistochemistry stain using antithyroglobulin antibody, which established the diagnosis of a metastatic lesion from thyroid papillary carcinoma. Total thyroidectomy, excision of scalp nodule, and 131I radiotherapy were performed. No further metastasis has been discovered during the last 12 months.
