Brown tumour is rarely the first symptom of hyperparathyroidism. It is a localized form of osteitis fibrosa cystica. Primary hyperparathyroidism is characterized by hypersecretion of parathormone in which bone loss occurs due to resorption of bone. Now-a-days diagnosis of hyperparathyroidism is done in asymptomatic or minimally symptomatic stage. In this case report, we present to you a rare case of brown tumour of maxilla and mandible in a 27-year-old male patient who presented with multiple painful left maxillary and mandibular swellings suspicious of neoplasia. These were diagnosed on Computed tomography (CT) as brown tumors. Parathyroid adenoma was diagnosed retrospectively on ultrasonography as cause of hyperparathyroidism.
