men·stru·al cycle

The series of bodily changes in women and other female primates in which the lining of the uterus thickens to allow for implantation of a fertilized egg. The cycle takes about a month to complete, with ovulation usually occurring around the midway point. If the egg produced is not fertilized, the lining of the uterus breaks down and is discharged during menstruation.

Incorporating color histopathology sections throughout, she covers interpreting results and communication between the pathologist and clinician, the normal endometrial cycle, pregnancy-related findings in normal and abnormal pregnancies, organic lesions, hormonally-related abnormal uterine bleeding, endometrial hyperplasia and preinvasive disease, malignancies, diagnostic pitfalls, and molecular aspects.
A normal endometrial cycle is associated with changes in both endometrial glands and stroma that allow the pathologist to diagnose microscopically the phase of menstrual cycle.
