Cutaneous nodes in a patient with advanced papillary carcinoma of the thyroid.

Cutaneous metastasis from thyroid carcinoma is infrequent. Leukemia as a second malignancy after treatment of thyroid cancer is also rare. We present a patient with a relapsed thyroid carcinoma treated with thyroid ablation with I 131 and loco-regional radiotherapy, who consulted by global worsening, weight lost, and multiple cutaneous nodes. Our patient is unusual in that she showed multisystem involvement at the time of hospital admission, and the specific skin lesions were the first sign of her acute monocytic leukemia.
