Although a Giant Cell Tumor (GCT) is usually regarded as a benign lesion based on the clinical appearance of the tumour, substantial bone deterioration may occasionally occur, rendering tumour management extremely difficult. GCTs are typically mono-ostotic, although, on rare occasions, they may manifest as high-grade polyostotic. Out of all basic bone neoplasms, the GCT accounts for 5% of cases. Despite this, the head and neck manifest as 2 to 4 per cent of all GCTs. There is a contemporary scarcity of documented case presentations of GCT diagnosed in the jaw bones. We are here to present an unusual case presentation of GCT of maxilla in a male patient.
