EVOLUTION AND REGRESSION IN BONE-PRIMARY HYPERPARATHYROIDISM

Primary hyperparathyroidism is still predominantly a symptomatic disease in India, though largely asymptomatic in the western world. The bone is the most commonly affected organ and the classic bone disease of primary hyperparathyroidism, osteitis fibrosa cystica, is characterized by subperiosteal bone resorption, osteopenia, and brown tumors. Regression and healing of these lesions are expected after normalization of hyperparathyroidism subsequent to parathyroidectomy, however in some cases these brown tumours may grow despite normalization of parathyroid hormone. The present case describes this phenomenon of evolution and regression of brown tumors in a young lactating lady
