An Interdental Radiolucent Lesion of Mandible: A Case Report and Differential Diagnosis

Abstract

Aim: The present article discusses a case which was an accidental finding in uncommon location. Case Report: A 70-year-old apparently healthy woman presented with proximal caries on mesial surface of canine and exhibited mild sensitivity to percussion. An intraoral periapical radiograph demonstrated interdental bone loss along with a diffuse unilocular radiolucent lesion between the canine and premolar region. Pathologies such as Radicular cyst, Lateral Periodontal Cyst, Collateral Keratocystic Odontogenic Tumor (KCOT), Squamous Odontogenic Tumor (SOT), Central Giant Cell Granuloma (CGCG), Extrafollicular Adenomatoid Odontogenic Tumor (AOT), other possible odontogenic and mesenchymal lesions with similar presentation in the anterior jaw were considered and discussed in our differential diagnosis. Conclusion: After histopathological examination of the incisional biopsy, the lesion was diagnosed of KCOT. The lesion was treated with carnoy's solution prior to surgical enucleation. The patient had been under regular follow-up for 2 years and showed no recurrence.
