Neglected cases of papillary and follicular thyroid carcinoma. Occurrence of subcutaneous scalp metastases.

Abstract

Three cases, two follicular and one of papillary thyroid carcinoma are reported. All three patients presented with subcutaneous cystic scalp metastases; they had a long-standing history of thyroid cancer, although two had never sought medical attention. We discuss this unusual clinical manifestation in patients with untreated well differentiated thyroid carcinoma.
