Langerhans cell histiocytosis presenting as brown lichenoid patches.
Langerhans cell histiocytosis (LCH) is related diseases characterized by proliferation of Langerhans cell with involvement of bone, skin, lung and other organs. LCH usually occurs in childhood and are presented as multiple small papules or eczematoid lesion mostly. We report a 50-year-old man with 3 brown lichenoid patches on left dorsal foot. He was diagnosed pulmonary LCH 5 years ago. Typical LC cells on skin lesion and CD1 complex positive staining confirm the diagnosis of LCH. We consider brown lichenoid patches may be a previously unreported cutaneous presentation in cutaneous or multisystem LCH.
