Recurrent giant cell tumour of the maxilla associated with both Paget's disease and primary hyperparathyroidism

Giant cell tumor of the mandible

A 53-year-old woman presented with left mandibular area pain, trismus, and facial numbness that had persisted for 4 years. Physical examination revealed a 3×5 cm, hard, non-tender, and round mass on the left mandibular area. Computed tomography and magnetic resonance imaging revealed an expansile tumor involving the left mandibular ramus and temporomandibular joint area with bone destruction, extending to the base of middle cranial fossa and left zygomatic bone. The mass at the segment of left mandible and zygomatic bone, and base of middle cranial fossa was removed. Pathological examination of the mass revealed a giant cell tumor. The defect was reconstructed with iliac bone for the mandible and temporal bone and fascia for the cranial bone and dura. The case is described along with a review of the literature.

Giant cell tumour (osteoclastoma) of the zygoma: an extremely unusual neoplasm

We report an extremely rare case of a giant cell tumour of the zygomatic bone in a 36-year-old female. The tumour was excised with healthy margins. The patient is asymptomatic without any evidence of recurrence 14 months postoperatively. To our knowledge, this is only the third reported case of this tumour occurring in the zygomatic bone in the medical literature.
