title: Some ultrastructural aspects of clear-cell uterine corpus carcinoma.
abstract: Light and electron microscopic study of a clear-cell carcinoma of the corpus uteri was undertaken. The clear cells of the investigated tumor showed a high degree of cellular differentiation as compared with the typical carcinomatous dark cell. They resemble the endometrial glandular cells of the secretroy type. The ultrastructural examination of the carcinomatous clear areas permits to distinguish these endometrial cells from those of mesonephric or adrenal origin.
