More than just tissue diagnosis in a patient with maxillofacial bony lesions and hypercalcemia.

Abstract

Brown tumors are a definitive feature of hyperparathyroidism. They are well-demarcated osteolytic lesions commonly in the appendicular skeleton. Primary hyperparathyroidism is typically suggested by hypercalcemia and hypophosphatemia on routine labs. Much more rarely do these cases present with a craniofacial mass. Here we investigate a unique presentation of terminal stage primary hyperparathyroidism with a growing maxillary mass emphasizing the importance of a broad differential diagnosis and key diagnostic studies. Hyperparathyroidism can present in very unique ways. As otolaryngologists in the frontline, we must think beyond just tissue diagnoses so that appropriate and expedited care may be implemented.
