Osteoblastoma of Mandible in Child: A Case Report

Osteoblastoma is considered as a bone tumor, which is benign and arises from non-odontogenic epithelium. This condition is quite rare in children and very few cases of osteoblastoma are reported. The case report describes osteoblastoma affecting mandible in an 8-year-old boy. It was noticed that the lesion began to show gradual enlargement and was painful. An excisional biopsy was carried out. Histopathological examination revealed eosinophilic bony trabeculae, lined by osteoblasts, with osteocytes within lacunae. Intertwining connective tissue showed delicate collagen fibers, numerous vascular channels, and extravasated RBCs. It was finally diagnosed as osteoblastoma based on the features of clinical, histological, and radiographic appearance.
