Giant cell tumor of the temporal bone

Abstract

Giant cell tumor (GCT) arises from undifferentiated mesenchymal cells of the bone marrow. GCT, a benign and locally aggressive tumor, is more commonly seen in the metaphysis of long bones. It may cause local bone destruction, recurrence, and pulmonary metastases (~1%). A 15-year-old male patient was admitted with complaints of swelling on the right face, a headache that has persisted for one year and progressively worsened in the last three months, and hearing loss. Craniotomy and total tumor excision were performed. Histopathological examination revealed a giant cell tumor of the bone. We present a case of temporal bone GCT with its clinical and radiologic features.
