- Abstract
Background: Langerhans cell histiocytosis (LCH) of the temporal bone is an uncommon disease that primarily affects the pediatric population; fewer than 40 adult cases have been reported in the literature. We present a rare case of LCH of the temporal bone in an adult patient and describe its clinical presentation, histopathologic findings, and management. Case Report: A 21-year-old male presented to the emergency department with progressively worsening right-sided ear pain refractory to outpatient oral antibiotics. Physical examination revealed mastoid tenderness and decreased right-sided hearing. Computed tomography (CT) scan suggested coalescent mastoiditis; the patient responded to inpatient antibiotics and was discharged. He returned 9 days later with persistent symptoms. Repeat CT scan revealed an osteolytic lesion on the temporal bone, and the patient was indicated for surgery. Intraoperative histology was consistent with LCH. Subsequent surveillance magnetic resonance imaging (MRI) suggested persistence of disease, and the patient responded to a course of radiation. Three months following radiotherapy, surveillance MRI and positron emission tomography scans revealed no evidence of recurrent disease. Conclusion: Diagnosis of LCH of the temporal bone is frequently delayed because of misdiagnosis of more common otologic diseases, including otitis media, otitis externa, andmastoiditis. The clinician's index of suspicion for LCH should be high if imaging reveals an osteolytic defect of the temporal bone; confirmation is via immunohistostaining of biopsy samples. The majority of cases respond to surgery, radiation, chemotherapy, or combination therapy, but delays in diagnosis and treatment may increase morb
