title: Cutaneous metastasis from papillary carcinoma of the thyroid gland. Report of two cases.
abstract: Two cases of metastatic skin tumors on the scalp appearing several years after thyroidectomy for thyroid papillary carcinoma are reported. Histologic examination of biopsy specimens from both patients revealed glandular-forming masses with intricate papillary folds in the dermis. The tumor epithelium was composed of single-layered cylindrical and cuboidal cells without atypia. Using the immunoperoxidase technic, many of the proliferating cells were shown to produce triiodothyronine (T3) and thyroglobulin (Tg).
