Metastatic disease can appear shortly after the initial diagnosis and operation or for up to 20 years later. Because of the difficulty in making a histologic diagnosis, the appearance of recurrent or metastatic disease in a patient previously operated on for hypercalcemia can be the first indicator that the tumor was malignant. Approximately 50% of the patients who experience recurrence will have distant metastases. The most common site of distant metastasis is the lung.[4,5] Some patients experience years of survival even after the diagnosis of distant metastases. Aggressive surgical resection has been associated with a 30% long-term survival in retrospective series.[3,6]
