Figure 2: Pathology of cervical biopsy showing primitive neuroectodermal tumor composed of (a) monotonous small round primitive cells with papillary and sheet patterns (H and E, ×100) and (b) Homer-Wright rosettes. In rosettes, differentiated tumor cells surround the neuropil (H and E, ×400). Immunohistochemical study of primitive neuroectodermal tumor showing (c) CD99 (brown color, DAB ×200) and (d) Friend leukemia integration 1 transcription factor positive (brown color, DAB ×200)
