Giant cell tumours of the maxilla and tibia presenting concurrently as an initial manifestation of primary parathyroid adenoma

ABSTRACT

A 14 years female of Afghan origin reported with maxillofacial and tibia growths causing progressive deformities since nine months, both were giant cell tumours on histopathology. Serum calcium was normal, but the parathyroid hormone was exaggerated [678pg/ml]. Ultrasound indicated and Tc-99m Setamibi scan confirmed a left lower parathyroid lesion. A 4cm length mass was identified, removed and proved to be a parathyroid adenoma. Two weeks later a subtotal maxillectomy and six weeks later anterior wedge osteotomy of the tibia were carried out. Serum parathyroid hormone level normalized
