Abstract: | We report a dumbbell-type solitary fibrous tumor in the cervical spine. Eight spinal solitary fibrous tumors have been reported
previously, but the cervical location is rare and this may be the first report of a dumbbell-type tumor. Histopathological
examination showed that the tumor was composed of spindle cells in a collagen-rich matrix, although regional variability was
noted. Diffuse immunostaining for CD34 and vimentin was noted in the cytoplasm of the tumor cells. This rare tumor should
be recognized in the differential diagnosis of cervical spinal tumors.
