A Rare Widespread Cutaneous Langerhans Cell Histiocytosis Manifested on 18F-FDG PET/CT

摘要

Here, we report the case of a patient with cutaneous Langerhans cell histiocytosis, which showed a large number of small high F-18-FDG-avid foci all over the body skin on PET/CT, accompanied with involved lymph nodes in bilateral axillas.
