Title: Langerhans cell histiocytosis presented as persistent diaper dermatitis: A case report


Langerhans cell histiocytosis presents most frequently in pediatric patients with cutaneous manifestations such as erythematous and scaly papules in the trunk or scalp and macerated plaques in intertriginous sites. We present a case of a seven-month-old patient who was brought with complaints of persistent diaper rash. The patient presented with skin fissures in intertriginous areas and pink color papules dispersed widely in the trunk and perineum. The skin biopsy revealed infiltration of abundant histiocytes, eosinophils, lymphocytes, and plasma cells, being CD207, CD1a, and S-100 positive by immunohistochemistry. Due to the diversified presentations of Langerhans cell histiocytosis and its propensity to mimic other dermatological conditions, physicians should have a clinical suspicion of this disease and consider it as a differential diagnosis among common skin diseases in pediatric patients.
