Well differentiated carcinoma of the thyroid cancer often metastasized to lymph nodes in the neck, but rarely to axillary lymph nodes. We experienced a case of recurrent thyroid cancer metastasized to the left axillary lymph nodes 7 years after a thyroidectomy for the primary cancer in a 45-year-old woman. There was a previous history of undergoing a total thyroidectomy with modified radical neck dissection (JT3, N3, M0) for a well differentiated thyroid carcinoma in 1987. Her postoperative course was uneventful and she was well for 7 years after the initial operation. In August 1995, 201T1 Scintigraphy revealed abnormal accumulation in the left axillary region. The tumor measured 3cm in size was palpated in her left axilla. The axillar tumor was excised. The microscopic examination showed the axillary lymph node metastasis from papillary carcinoma of the thyroid. Postoperative scintigraphy did not show any abnormal accumulation. In this case, the lymphatic flow into the subclavian lymph node might have been changed toward axillary lymph node because the cervical metastatic lymph nodes were as large as 7×8cm in size.
