چکیده
Extraskeletal myxoid chondrosarcoma (EMC) is an uncommon but distinct entity with clearly different clinicopathological, immunohistochemical, cytogenetical and histogenetical features from conventional skeletal chondrosarcoma. Because of its better prognosis in comparison to conventional skeletal chondrosarcoma, the right diagnosis is essential. A case of EMC occuring in the external auditory meatus, coexistent with in situ squamous carcinoma of the covering epithelium is being presented. This is the first report of this tumor coexistence.
