Langerhans Cell Histiocytosis (LCH) is a rare neoplasm of the hematopoietic system, characterized by the clonal proliferation of Langerhans cells and it is more common in children. We present two interesting adult cases of LCH, diagnosed with the help of FDG PET-CT imaging which is often challenging to diagnose due to its rarity and nonspecific clinical presentation.
朗格汉斯细胞组织细胞增多症（LCH）是一种罕见的造血系统肿瘤，其特征为朗格汉斯细胞的克隆性增殖，在儿童中更为常见。我们报告两例有趣的成人LCH病例，借助氟代脱氧葡萄糖正电子发射断层扫描-计算机断层扫描（FDG PET-CT）成像得以诊断，由于其罕见性和非特异性临床表现，LCH的诊断通常具有挑战性。
