Cutaneous Intertriginous Langerhans Cell Histiocytosis in Adults: A Case Report and Systematic Review

This systematic review encompasses the largest compilation of adult cutaneous intertriginous LCH cases in the medical literature to the authors' knowledge to date. This study identifies an important clinical presentation of this rare, commonly pediatric diagnosis; highlights trends among these cases and important clinical mimickers; and serves as a reminder to clinicians to maintain suspicion for LCH in adult populations, particularly in the setting of intertriginous cutaneous involvement.
