The pathogenesis of ovarian inclusion cysts and cystomas.

Sections from 1000 ovaries were examined in order to elucidate the pathogenesis of germinal inclusion cysts and ovarian cystomas. Reconstructions and dynamic interpretations of the morphology examined led to the conclusion that these lesions are almost always initiated by the mechanisms of ovulation, both normal and abnormal, and the consequent alterations of the ovarian surface. These mechanisms are described.
