PARATHYROID ADENOMA PRESENTING AS MULTIPLE BROWN TUMORS AND SEVERE ASYMPTOMATIC HYPERCALCEMIA

Introduction. Primary hyperparathyroidism may have several presentations, varying from an incidental asymptomatic biochemical finding to gastrointestinal, psychiatric, renal and bone manifestations. Brown tumors are rare non-neoplastic lesions because of abnormal bone metabolism. Herein, we describe a patient who presented with lytic bony lesions and severe asymptomatic hypercalcemia due to parathyroid adenoma. Case presentation. A 38 -year -old male presented with multiple painful bony lesions over upper and lower limbs. Radiographs of long bones showed multiple lytic lesions with cortical thinning. Investigations revealed hypercalcemia and hyperparathyroidism. A radionuclide scan showed parathyroid adenoma. The patient was treated for hypercalcemia and a parathyroidectomy was performed. Conclusions. In a patient presenting with multiple bony swellings and asymptomatic hypercalcemia, hyperparathyroidism should be suspected. Parathyroid adenoma is a treatable cause of primary hyperparathyroidism.
