The giant cell tumour is a benign but locally aggressive tumour accounting for 5% of all bone tumours typically seen at the metaphyseo-epiphyseal ends of long bones with 1% incidence in skull bones. We are presenting a case report of 40year old female with GCT of hard palate. An initial pre-operative plan was hard palate removal with complete tumour clearance trans-orally with iatrogenic oro-nasal fistula with rehabilitation to be done with obturator for closure of fistula and dentures to aid chewing. However, intra-operatively the surgical plan was revised and the tumour was removed with preservation of party wall mucosa. Thus, we present this case due to its clinical rarity and academic interest.
