Adult Lumbar Langerhans Cell Histiocytosis: A Case Report

Langerhans cell histiocytosis (LCH) is an extremely rare inflammatory myeloid tumor disease. This article reports a 25-year-old male patient who sought medical attention for one month due to persistent lower back pain. Imaging examination suggests the possibility of tumor like lesions in the L3 vertebral body, which was ultimately diagnosed as LCH through surgical pathological biopsy. This case can provide important reference for clinical doctors and other frontline medical personnel, enrich the existing knowledge base of adult lumbar LCH, improve understanding of the disease, and reduce misdiagnosis rate.
