Recurrent follicular thyroid carcinoma presenting as a cutaneous lesion. An unusual case of pigmented skin lesion.

Abstract

Follicular thyroid carcinoma most commonly metastasises to the lungs, liver, and non-cranial bones. Where skin metastases have occurred, this has been in the context of diffuse metastatic disease, and most commonly occur in the scalp. Cutaneous deposits in the neck have been described in papillary thyroid carcinoma, but we believe this to be the first description of cancer recurrence presenting as cutaneous metastatic follicular thyroid carcinoma. A pigmented skin lesion in a patient with a history of thyroid cancer could represent a metastasis and should be treated with suspicion.
