Primary Hyperparathyroidism Masquerading Malignancy: A Case Report

Skeletal manifestations in the form of brown tumors are rare and according to literature occur in less than 2% of patients suffering from any form of hyperparathyroidism. Such rare and multiple benign lesions may simulate a malignant neoplasm and pose a real challenge for the clinician in its differential diagnosis. We present a case that was evaluated for multiple lytic lesions with a strong suspicion of malignancy but turned out to be a case of primary hyperparathyroidism. doi:10.4021/jmc2010.07.106e
