title: Mohs chemosurgery for local control of giant recurrent papillary thyroid cancer.
abstract: BACKGROUND
  Papillary thyroid carcinoma (PTC) generally has a good prognosis but may have an aggressive course, particularly in the elderly. Standard treatment consists of radioactive iodine and thyrotropin suppression with superphysiological doses of thyroid hormone. Other modalities are less commonly used. We report perhaps the first patient with PTC who was treated with Mohs chemosurgery.
  
  
  CONCLUSIONS
  The patient was a 94-year-old woman who was diagnosed at age 67 with PTC and underwent a near-total thyroidectomy. The PTC recurred in the cervical nodes and reached the size of 8 x 5.5 cm by age 89. The tumor had become exposed and was hemorrhaging. By age 92 it measured 10 cm, encompassed the right common carotid artery, and was invading the trachea and larynx. In order to implement local control, we applied Mohs ointment. She also required blood transfusions. After approximately 1 month, the tumor had flattened, and the hemorrhaging stopped, and the patient was able to be discharged from the hospital to home nursing.
  
  
  CONCLUSIONS
  Treatment with Mohs chemosurgery should be considered in the rare patient with exposed locally aggressive PTC for palliation and improved quality of life.
