Ciliated cysts in the human uterine tube epithelium were investigated with the transmission electron microscope. The cysts were about 3–9 µm in diameter and were provided with many ciliary apparatuses and microvilli. Degenerative changes of these cilia, such as electron-dense round or irregular bodies and amorphous substance, were observed in many cysts, but complete disappearance of ciliary structures was not detected in any ciliated cysts. The ciliated cysts were mostly observed in basal cells and were occasionally found in ciliated cells bordering the tubal lumen. In the basal cells, these cysts distended with the increase in degenerated cilia. Distended ciliated-cyst-containing cells became exposed directly to the tubal lumen. U- or reverse Ω-shaped deep indentations of the apical surface of ciliated cells confirmed the opening of ciliated cysts into the lumen. It was suggested that the ciliated cysts result from the premature differentiation of basal cells or disturbed migration of centrioles in ciliogenic cells.
