Langerhans' cell histiocytosis(LCH)is a rare condition caused by the proliferation of abnormal Langerhans' cells. A 5-year-old boy presented with LCH in the left temporal bone. He complained of a left ear canal polyp and otorrhea. Excisional biopsy was performed and a diagnosis of LCH was made. As the patient was five years old and had no pain with single focal LCH,we observed the patient without treatment. Then the polyp became smaller and faded away after five months. There has been no evidence of recurrence in 2 years.
