Langerhans Cell Histiocytosis in a Pediatric Patient with Simultaneous Gastrointestinal and Skin Involvement: A Case Report and Literature Review

Background: Langerhans cell histiocytosis (LCH) has heterogeneous presentations involving single or multiple systems, but simultaneous isolated skin and gastrointestinal involvement is not common. Case report: A female infant with intermittent bloody diarrhea was unresponsive for treatment of food allergy. Histology of gastric and colonic tissues demonstrated Langerhan’s cell histiocytosis. The infant also had red rashes that were histologically proven Langerhan’s cell histiocytosis. Chemotherapy utilized vincristine, cytarabine and prednisone. The bloody diarrhea and rash completely resolved with no recurrence in the 11 months of follow-up. Conclusion: Langerhan cell histiocytosis may present with simultaneous gastrointestinal and skin involvement.
