A Case Report of Pediatric Langerhans Cell Histiocytosis: Current Approach and Diagnostic Challenges for Dermatologist

Abstract

Abstract Langerhans Cell Histiocytosis (LCH) is a chronic and rare myeloproliferative disorder caused by disorders in Lang-erhans cell proliferation in various organs and tissues. LCH has a wide variety of clinical manifestations, making it difficult to diagnose. Cutaneous manifestations are polymorphic in the form of purpura, papule, vesicles and pustules. LCH can involve vital organs such as the liver and lungs as well as the hematopoiesis system that usually gives a poor prognosis. The prognosis is also influenced by the age of patient, organ dysfunction and response to the first 6 weeks of chemotherapy treatment. A 3-year-old girl reported a major complaint of an abscess-like lesion in the region of neck accompanied by an extensive purpura of scalp, neck and inguinal areas accompanied by vulvar erosions. The immunohistochemical and histopathologic examination support LCH and the clinical improvement after intravenous administration of intravenous 3 mg/m2 Vinblastine chemotherapy, 75 mg/m2 etoposide, oral 40 mg/m2 per prednisone. After the 6th cycle of chemotherapy, the patient died.
