We report here a case of unusually large brown tumor of mandible mimicking cherubism in a patient with secondary hyperparathyroidism (HPT). The patient is a young male with a large head and a protruding jaw with an open mouth appearance. Initial clinical appearance looked like cherubism. However further clinical, biochemical, and radiological evaluation revealed a large brown tumor in a case of prolonged secondary HPT, which was confirmed on histopathology. All of the typical advanced radiological features of HPT were noted, highlighting the severity of progression of the disease. This case emphasizes the need for surveillance of serum calcium levels on routine biochemical investigations as to enable an early diagnosis of HPT. With timely proper management, such cases should be on the decline in the future.
