Papillary thyroid carcinoma is the most common type of thyroid malignancy. It has better prognosis and rarer incidence of distant metastasis than other types of thyroid malignancy. However, once distant metastasis happens, its result will be bad. They mostly spread to the lungs and bones. and rarely to the brain. We report a patient with a papillary thyroid carcinoma metastasis to the lymph nodes. the ribs. the brain, and the lungs. The patient underwent total thyroidectomy, radioiodine ablation, rib partial resection, and lung wedge resection. However, upon progress of metastasis. the patient insisted on being treated with traditional Korean medical treatment using allergen-removed Rhus Verniciflua Stokes (A-RVS) instead of the conventional treatment including chemotherapy. The size of the tumor partly decreased, and the patient showed no side effects. This case report brings forth the importance of a thorough study in papillary thyroid carcinomas and their metastasis from the traditional Korean medical point of view, along with the long-term effect of allergen-removed Rhus Verniciflua Stokes (A-RVS).
