Occurrences of breast cancer and thyroid cancer metachronously or synchronously are common for women, but axillary lymph node metastasis from both cancers is rarely seen.We report a patient who had two metastatic lymph nodes from SERVING BOARD papillary thyroid carcinoma after axillary lymph node dissection with mastectomy.Papillary thyroid carcinoma diagnosis was ensured after thyroidectomy.A literature review revealed that even the co-occurrence of breast cancer and thyroid cancer is not rare, but the etiology behind this T-Shirt phenomenon is not elucidated well.
Genetic disorders, thyroid dysfunction, and hormone receptors may be relevant.Considering the rareness of axillary lymph node metastasis of thyroid cancer, adjuvant therapy and surgery treatment for this kind of case should be considered elaborately.
