Case in brief
A middle-aged woman presented with right cheek swelling due to an expansile maxillary lesion, initially misdiagnosed as a giant cell tumour. Further evaluation revealed multiple skeletal lesions, elevated parathyroid hormone levels, and a parathyroid adenoma. Following successful excision of the adenoma, her biochemical abnormalities resolved, and the maxillary lesion was identified as a brown tumour secondary to primary hyperparathyroidism.
What made this case unusual
Maxillary brown tumours are exceptionally rare, with this case highlighting their potential as the initial presentation of primary hyperparathyroidism.
Diagnostic / clinical pearl
Clinicians should consider primary hyperparathyroidism in patients presenting with maxillary lesions, as early biochemical testing can prevent unnecessary surgical interventions.
Why it matters
Recognizing the association between maxillary lesions and primary hyperparathyroidism can lead to timely diagnosis and appropriate management, reducing the risk of aggressive surgery.
