Ewing's sarcoma of the sacrum.
A lytic lesion with soft-tissue extension in the sacrum of a 47-year-old man was needle-biopsied under computed tomographic (CT) guidance using an 18-gauge cutting needle. The cytologic appearance of the lesion and immunohistochemical staining were diagnostic of Ewing's sarcoma. Specifically, a new marker (O13) for the presence of glycoprotein p30/32 mic2 in Ewing's sarcoma was utilized.
