Langerhans Cell Histiocytosis Mimicking Osteomyelitis in an Infant

Langerhans cell histiocytosis (LCH) is a relatively rare disorder, accounting for less than 1% of all osseous lesions. LCH involving bone has been reported in a wide age distribution ranging from the first few months to the 8th decade of life.[1] Pain and swelling of the affected area occur most commonly. Other findings are related to the bone involved. Clinically and imaging studies can point out malignancy or infection.[2] Herein we report a case of Langerhans cell histiocystosis of femeur which simulated as osteomyelitis.
