Multiple Brown Tumors in Primary Hyperparathyroidism Causing Pathological Fracture: A Case Report of a 21-Year-Old Adult Male

Multiple brown tumors are more common in females and older age groups and an unlikely site is the long bones. We report a case of a 21-year-old male presenting with a pathological fracture at the left neck of the femur. Laboratory investigations showed elevated parathyroid hormone (PTH) and serum calcium levels (PTH-dependent hypercalcemia). A CT scan revealed multiple osteolytic lesions in the pelvis and femurs, and a Tc-99m sestamibi scan showed a solitary parathyroid adenoma. We demonstrate this rare case and illustrate the importance of the consideration of multiple brown tumors in young males presenting with multiple osteolytic lesions at the long bones in the differential diagnosis. Every physician needs to have a high clinical suspicion of primary hyperparathyroidism innovation, in those who present with osteolytic lesions, with respect to the patient’s age and gender.
