Hamartomas, occurring in oral and maxillofacial region are basically indigenous tissue malformations that arise from epithelial derivatives, mesenchymal derivatives and odontogenic derivates. Vascular anomaly, is a mesenchymal hamartomatous condition- a broader term describing condition of blood vessels including abnormal number, structure and position imparting blue/purple colour to oral mucosa. Such anomalies are broadly classified into two basic types like vascular tumours and vascular malformations. A clinician should possess skills and knowledge for identifying such lesions and be aware of its diagnosis to avoid any event of uncontrolled bleeding in the dental chair.
