HPT usually results from increased secretion of parathyroid hormone (PTH). We present a rare case of brown tumour of anterior maxilla presenting as a first sign of previously undiagnosed secondary HPT, to emphasise that giant cell lesions of jaw bones should routinely be screened for PTH levels to rule out underlying endocrine abnormalities and oral manifestation is the earliest manifestation of many systemic diseases and careful evaluation of oral cavity by physician gives information to underlying systemic pathology.
