Intraoral lipoma is a rare benign, gradually progressive tumour of adipose tissue. Although extremely common tumour of mesenchymal origin elsewhere in human body where fatty tissue is normally present, their existence in oral cavity however, is rare. Lipoma of tongue, despite being devoid of fat cell is also unusual site and very rare, representing about 0.3% of tongue tumours. Various theories explain pathogenesis of this adipose tissue tumour but cause still remains idiopathic. Here, a rare case of lipoma on the lateral aspect of tongue is reported in 69-year-old female. Tumour was completely excised and defect closed by transpositional flap.
