Neuromuscular choristoma of the internal auditory meatus.
Choristomas of the internal auditory meatus are exceedingly rare tumors. In most cases, neuromuscular choristomas have initially been misdiagnosed as vestibular schwannomas (VS).

To date, only about forty cases of neuromuscular choristomas have been reported with only five s...
متن کاملExtraskeletal myxoid chondrosarcoma of the external auditory meatus
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 m...
