Langerhans cell histiocytosis (LCH) or histiocytosis X refers to a group of diseases that are characterized by clonal proliferation of histiocyte with similar characteristics to Langerhans cells, which affect different organs of the human body, including the temporal bone. The present study describes the clinical case of a 42-year-old patient admitted to surgery for acute chronic otomastoiditis on the right temporal bone. Axial Computerized Tomography (CT) revealed petromastoid osteolytic lesions, dehiscence of the lateral sinus and external semicircular canal and a solution of continuity of the tympanic tegmen, but without infiltration of neurological structures. The diagnosis of temporal bone LCH was confirmed with histopathological and immunohistochemical exams. Depending on the type of lesion, there are different therapeutic modalities for LCH of the temporal bone that include surgery, chemotherapy, radiotherapy and even corticotherapy. In this case, the patient was submitted to mastoidectomy the right, followed by corticotherapy (dexamethasone) and chemotherapy (vinblastine). Up to date, he has not yet had any relapse, but is still on follow up.
