Background:
Polypoid endometriosis (PEM) is a rare and unique type of endometriosis. To date, no article has provided a systematic report of this disease. The current article provides a complete report on rare PEM based on ultrasound, magnetic resonance imaging, intraoperative findings and postoperative pathology data.
Case Summary:
A 38-year-old female patient was admitted to our hospital after complaining of "vague pain in the right lower quadrant with an aggravated menstrual period for 8 mo". The patient underwent laparoscopic exploratory surgery on January 7, 2022. The postoperative pathology revealed extensive PEM.
Conclusion:
PEM is a type of endometriosis that is a benign disease but has biological properties similar to malignant tumours.

Oogenesis
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
Proliferative Phase
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
