A Case of an Adult-Onset Langerhans Cell Histiocytosis Involving the Temporal Bone / 대한이비인후과학회지

ABSTRACT

Langerhans cell histiocytosis (LCH) is a rare disease characterized by clonal proliferation of Langerhans cells. The temporal bone is frequently involved in pediatric LCH cases, but there have been few reports of adult LCH with temporal bone involvement. We present a case of adult onset LCH affecting the temporal bone. The diagnosis was made by biopsy, based on histopathologic findings of Langerhans cells. Diagnostic and therapeutic considerations of LCH involving the temporal bone are discussed.
