Aneurysmal bone cyst of the mandible: A case report

Abstract

Abstract Aneurysmal bone cyst (ABC) is a relatively rare, benign osteolytic lesion that typically involves long bones. Approximately 2% of this tumour occurs in the jaws, with the posterior portion of the mandible being the predominant site. This lesion usually presents in the first two decades of life without sex predilection. Clinically and radiographically, ABCs are known for their diverse features, therefore often posing a diagnostic dilemma. This is the case report of a 2 year old boy with hereditary Thrombocytopenia, who was referred to us for management of his symptomatic, non healing traumatic ulcer on the right buccal mucosa and swelling of his right cheek. The lesion was initially diagnosed as haemangioendothelioma by the referring Hospital. Based on the MRI, panaromic radiograph and CT images, the lesion is suggestive of ameloblastoma of the right mandibular. Histopathological examination revealed that the lesion is consistent with ABC. The lesion was treated by surgical curettage under general anaesthesia. After one year follow up, clinical signs and symptoms have resolved well. As ABCs are known for its various clinical and radiological features and severity, histopathological examination is essential for definitive diagnosis and management.
