WebPituicytoma is composed of compact, bipolar spindle cells (with abundant eosinophilic cytoplasm and moderately sized, oval to elongate nuclei) forming fascicular or storiform pattern. There is no infiltration of the surrounding tissue or mitotic activity. Rosenthal fibers and eosinophilic granular bodies are also absent. WebBrat et al. described nine patients with pituicytoma, all of which strongly stained for vimentin and S-100 protein. They concluded that pituicytomas are low-grade gliomas. The presence of the S-100 protein in several ""granular cell myoblastomas"" of the orbit further supports the theory that these tumors are of glial origin.
