Langerhans cell histiocytosis is a disorder of the mononuclear phagocytic system. Virtually any organ can be involved, the bone, skin, lungs, and pituitary gland being the most common. We describe the case of a 30-year-old man who presented with painless neck swelling. 18 F-FDG PET/CT showed bilateral bulky parotid and submandibular glands with increased metabolic activity. Histopathology confirmed the diagnosis of Langerhans cell histiocytosis. To our knowledge, there has been no description of 18 F-FDG PET/CT findings in Langerhans cell histiocytosis of salivary glands in literature. We aim to aid in the diagnosis and management of this rare presentation.
朗格汉斯细胞组织细胞增生症是一种单核吞噬细胞系统的疾病。几乎任何器官都可能受到影响，最常见的是骨骼、皮肤、肺部和垂体。我们描述了一名 30 岁男性的病例，他表现为无痛性颈部肿胀。18F-FDG PET/CT 显示双侧腮腺和颌下腺肿大，代谢活性增高。组织病理学证实了朗格汉斯细胞组织细胞增生症的诊断。据我们所知，在文献中尚未有关于唾液腺朗格汉斯细胞组织细胞增生症的 18F-FDG PET/CT 表现的描述。我们旨在帮助诊断和管理这种罕见的表现。
