title: Myxoid chondrosarcoma of the external auditory meatus.
abstract: Extraskeletal myxoid chondrosarcoma presenting in the head and neck is extremely rare. Histological diagnosis is difficult and requires close co-operation between clinician, radiologist and pathologist. The tumour has a good prognosis in comparison to myxoid chondrosarcoma of the bone but surgical resection may be difficult due to its gelatinous nature. We present a case of extraskeletal myxoid chondrosarcoma originating in the external auditory meatus of a 42-year-old man. This is the first report of this tumour in this site.
