Abstract
A soft tissue tumor of a 17-year-old Korean girl was observed light and electron
microsopically, which revealed the featured compatible with extraskeletal Ewing's
sarcoma.
The identity to Ewing's sarcoma of osseous origin was extended to the ultrastructural
level. The tumor was composed of two types of cells, namely, principal cells and
secondary cells. Although multiple sections of the tumor were examined, there was no
definite evidence to indicate the cell of origin on the ultrastructural study.
