Abstract : Primary hyperparathyroidism is a disease characterized by excessive secretion of parathormone. During the course of this disease, bone loss occurs, particularly depending on resorption of the skeletal system. One of the complications of primary hyperparathyroidism is fibrotic, cystic bony changes which is called Brown tumor. Skeletal manifestations in the form of Brown tumors are rare and 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 are presenting two such cases that were evaluated for multiple lytic expansile lesions with a strong suspicion of malignancy and fibrous dysplasia but turned out to be cases of primary hyperparathyroidism due to parathyroid adenoma
