Adult Langerhans Cell Histiocytosis: Solitary and Multisystemic Involvement Detected on FDG PET-CT Scan.

Abstract

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.
