title: Carcinoma erysipeloides associated with anaplastic thyroid carcinoma.
abstract: Cutaneous metastases from carcinoma of the thyroid gland are rare and carcinoma erysipeloides is even rarer. We present the clinical, histological, and immunohistochemical features of inflammatory erysipeloid metastases arising from an anaplastic carcinoma of the thyroid gland. In this case the anaplastic carcinoma probably transformed from a pre-existing, long-standing papillary carcinoma of the thyroid gland. Although visible inflammation is a hallmark of many benign skin disorders, it is not commonly present in cutaneous malignant metastases. As a result, the significance of a marked inflammatory changes in association with metastatic skin disease may not be recognized. Dermatologists need to be aware of the potential for inflammatory manifestations in cutaneous metastases from a thyroid carcinoma.
