An osteoid osteoma is a benign bone neoplasm with limited growth potential, characterized by significant nocturnal pain that usually responds to non-steroidal anti-inflammatory drugs (NSAIDs). The tumor may occur in any part of the skeleton, most commonly in the lower extremities and vertebrae.
A 46-year-old female was diagnosed with a rare case of an intra-articular variant of osteoid osteoma, involving the articular eminence and glenoid fossa of the temporo-mandibular joint (TMJ).
The tumor presented as a painful progressive swelling in the right pre-auricular area that had lasted for more than 2 years and which had been previously treated as a TMJ disorder. Computed tomography revealed a well-defined heterogeneous nidus involving the articular eminence of the TMJ. Surgical excision was performed and histological examination confirmed the diagnosis. In this article, in addition to describing the case, all cases of osteoid osteoma of the jaws and TMJ reported in the English-language literature are reviewed.
Osteoid osteoma involving the TMJ is a rare presentation and may exhibit ambiguous symptoms, which could lead to misdiagnosis and delayed treatment.
骨样骨瘤是一种生长潜力有限的良性骨肿瘤，其特征是夜间疼痛明显，通常对非甾体抗炎药（NSAIDs）有反应。该肿瘤可发生于骨骼的任何部位，最常见于下肢和椎骨。
一名46岁女性被诊断为罕见的关节内型骨样骨瘤，累及颞下颌关节（TMJ）的关节结节和关节盂。
肿瘤表现为右耳前区疼痛性进行性肿胀，持续超过2年，此前一直被当作颞下颌关节紊乱症治疗。计算机断层扫描显示颞下颌关节关节结节处有一个边界清晰的不均匀瘤巢。进行了手术切除，组织学检查证实了诊断。在本文中，除了描述该病例外，还对英文文献中报道的所有颌骨和颞下颌关节骨样骨瘤病例进行了综述。
累及颞下颌关节的骨样骨瘤较为罕见，可能表现出不明确的症状，从而导致误诊和治疗延误。
