Langerhans cell histiocytosis (LCH) is a group of unexplainable abnormal proliferation and aggregation of
Langerhans cell. LCH can be classified into four clinical variants
Letterer-Siwe disease,
Hand-Schüller-Christian
disease,
eosinophilic granuloma, and
congenital self-healing LCH. LCH is most prevalent in
children. Lesions can be localized in a single system or multiple organs, and clinical manifestations vary depending on the affected organs. The
skin and mucocutaneous
tissues are the starting point of the affected
tissue. This study presents a LCH case characterized by
transient self-healing. This case can further provide references for the
clinical diagnosis and
treatment of LCH.
