Abstract
Langerhans cell histiocytosis (LCH) is a rare disorder characterized by uncontrolled proliferation of Langerhans cells. We report a case of a 5-years old girl with left post auricular swelling, otalagia and otorrhea of 2 month duration, High resolution computed tomography of temporal bone show destructive expanding tissue density mass. Apparent diffusion coefficient is 1.08×10�?³ mm²/s in diffusion weight magnetic resonance imaging .Post auricular incision revealed a pinkish, firm granulomatous mass occupied middle ear and mastoid Histopathological examination revealed a mixture of Langerhans histocytes and eosinophils. CD1 and S100 are positive in mmunohistochemistry.
