Abstract

Langerhans cell histiocytosis (LCH) is a heterogeneous disease, characterized by accumulation of dendritic cells with features similar to epidermal Langerhans cells. It is a rare entity that may involve various organ levels such as the skeletal, pulmonary, hematopoietic and lympho-vascular systems. The patient was a 1-year-old female presented with fever associated with otorrhea and palpable cervical lymph node for 4 days. Neck ultrasonography and Computed tomography imaging revealed multiple enlarged lymph nodes suggesting suspicious malignant morphology. Lymph node biopsy was performed under general anesthesia. Histological and immunophenotypic examination showed the lymph node to be consistent with LCH. The patient was given chemotherapy.
