Osteoid osteoma is a rare benign bone lesion that is often confused with the osteoblastoma. The osteoid osteoma comprises of 3% of all the primary bone tumours usually found in the long bones and vertebrae with the facial skeleton being the most infrequent site. The lesion usually presents with the swelling and pain that resolves with non-steroidal anti-inflammatory drugs (NSAIDs). Here, we report a case of osteoid osteoma of retromolar trigone, the site which has not been reported in the literature, in a 50-year male patient with a complaint of hard swelling on retromolar trigone associated with the mild intermittent localised pain that aggravated at night and on mastication. Excision of the lesion was carried out with chisel and mallet under local anesthesia with uneventful recovery and no recurrence at the 6 months follow-up. Key Words: Benign, Osteoid osteoma, Retromolar trigone.
骨样骨瘤是一种罕见的良性骨病变，常与成骨细胞瘤相混淆。骨样骨瘤约占所有原发性骨肿瘤的 3%，通常发生在长骨和椎骨，而面骨是最不常见的部位。病变通常表现为肿胀和疼痛，用非甾体抗炎药（NSAIDs）可缓解。在这里，我们报告了一例发生在磨牙后三角的骨样骨瘤病例，该部位在文献中尚未报道，患者为 50 岁男性，主诉磨牙后三角有硬性肿胀，伴有轻度间歇性局部疼痛，夜间和咀嚼时加重。在局部麻醉下用凿子和锤子切除病变，术后恢复顺利，6 个月随访无复发。关键词：良性、骨样骨瘤、磨牙后三角。
