Cutaneous metastasis from thyroid carcinoma is rare. It's often combined with other metastasis exceptionally isolated. We report the case of a 60 year-old patient operated in 2008 with thyroid surgery without a surgery report and an anatomo-pathological examination. She presents a huge scalp lesion with bone lysis visible with MRI and scanner. Samples confirmed the metastasis of a follicular thyroid cancer.
