It occurs in 0.5% to 4.3% of patients [1], and is usually associated with high levels of thyroid hormones. The classification of PM includes four forms: non-pitting edema;plaque;nodular;or elephantiasis [1]. Mild PM often regresses spontaneously, but the severe, elephantiasic variant is typically progressive and refractory to treatment. Elephantiasic pretibial myxoedema (EPM) is characterized by massive edema, skin fibrosis and verrucous nodule formation, and it clinically resembles lymphedema. Herein, we describe a man with Graves’ disease presenting with EPM for nearly 2 years. Although advanced cases have been described in the literature, to our knowledge, none have reached this level of severity.展开更多
