A Case of Multiple Primary Parathyroid Cancer / 대한이비인후과학회지

Parathyroid cancer is a rare disease, of which about 700 cases have been reported since first being described by de Quevain in 1904. In particular, multiple primary parathyroid cancer is extremely rare and to our knowledge only 4 cases have been reported in the literature since the first report in 1990. A 41-year-old male patient was presented with bilateral neck mass, polydypsia and polyuria with hypercalcemia and high parathyroid hormone level. The patient underwent surgery at Kosin University Gospel Hospital and was diagnosed as double parathyroid cancer on pathologic examination. So, we report this rare case with literature.
