A very rare mass mimicking paraganglioma in the parapharyngeal area: extraskeletal osteosarcoma.

Extraskeletal osteosarcoma is a very rare type of sarcoma that is considered as one of the subtypes of osteosarcoma. This sarcoma type is very rare in the head and neck area. There is no reported case in the parapharyngeal area. Our case is the first in the literature since it is located in the parapharyngeal area. We present the 69- year-old male patient with extra-skeletal osteosarcoma arising from the parapharyngeal area, with current literature.
