Parietal metastasis is a very rare secondary location of papillary thyroid carcinoma. It associated with poor prognosis. We report a case of a 61-year-old woman with parietal metastasis from papillary thyroid carcinoma. The patient presented a parietal nodule on the back. In her past history, she had been diagnosed papillary thyroid carcinoma after total thyroidectomy and also reoperated for local recurrence. The CT scan performed has revealed metastasis to the lungs, bones, lymph nodes and adrenal glands. The parietal nodule was excised and submitted for histopathological examination. The histologic and immunohistochemical findings confirmed the thyroid origin. Although papillary thyroid carcinoma is a relatively indolent tumour, it can exhibit an unusual metastatic behaviour.
