Langerhans cell histiocytosis (LCH) is rare in adults. Oral and maxillofacial LCH commonly affects the bones of the skull and jaws. Here we report a case of a 57-year-old man with a painless oral mass evaluated by F-FDG PET/CT. PET/CT showed a solitary F-FDG-avid tumor in his left hard palate. LCH was confirmed after surgery. This case reminds us that LCH should be considered in an adult with hypermetabolic hard palate lesion on F-FDG PET/CT.
朗格汉斯细胞组织细胞增生症（朗格汉斯细胞组织细胞增生症）在成人中较为罕见。口腔和颌面朗格汉斯细胞组织细胞增生症通常影响颅骨和颌骨的骨骼。在这里，我们报告了一例 57 岁男性的病例，他因无痛性口腔肿块接受 F-FDG PET/CT 检查。PET/CT 显示其左硬腭有一个孤立的 F-FDG 摄取肿瘤。手术后确诊为朗格汉斯细胞组织细胞增生症。本例提醒我们，在 F-FDG PET/CT 上表现为硬腭高代谢病变的成年患者中应考虑朗格汉斯细胞组织细胞增生症。
