Giant cell tumors of the head and neck are rare. We describe the case of a 50-year-old man who presented with otalgia and eustachian tube dysfunction. After his symptoms persisted despite aggressive medical management, further investigation revealed the presence of a firmness in his left parotid tail. Computed tomography identified a heterogeneously enhancing mass in the left masticator space. The tumor was removed surgically, and it was diagnosed on histopathology as a giant cell tumor. The patient recovered uneventfully and was closely followed for signs of recurrence. To the best of our knowledge, ours is the first reported case of a giant cell tumor in the masticator space. We review the literature on giant cell tumors of the head and neck, with particular attention given to cases involving the temporomandibular joint.
头颈部巨细胞瘤较为罕见。我们报告一例50岁男性，其表现为耳痛和咽鼓管功能障碍。尽管进行了积极的药物治疗，症状仍持续存在，进一步检查发现其左腮腺尾部有硬结。计算机断层扫描显示左侧咀嚼肌间隙有一个不均匀强化的肿块。肿瘤通过手术切除，组织病理学诊断为巨细胞瘤。患者术后恢复顺利，并密切随访有无复发迹象。据我们所知，我们的病例是首例报道的发生于咀嚼肌间隙的巨细胞瘤。我们对头颈部巨细胞瘤的文献进行了综述，特别关注了涉及颞下颌关节的病例。
