Adenomatoid odontogenic tumour (AOT) is an uncommon benign lesion derived from the complex system of dental lamina or its remnants. It is categorized into 3 variants (follicular, extrafollicular and peripheral). It affects young individuals with female predominance, commonly located in anterior maxilla and is usually associated with impacted canine. A 20 year old female presnted with a large radiolucent lesion associated with impacted canine in mandibular anterior region which was clinically diagnosed as dentigerous cyst (DC). The microscopic examination revealed the presence of AOT in the fibrous capsule of the DC. This case represents an odontogenic cyst with neoplastic development, containing both epithelial and mesenchymal components. Very few cases of AOT associated with DC have been reported till date.
