Patient's question:
NoDoctor's answer:
Endometriosis is a benign gynecological condition caused by the invasion of the endometrium into the uterine muscle layer. Pathologically, it is characterized by hypertrophy of the uterine muscle layer, with island-like distribution of endometrial glands and stroma interspersed between the muscle bundles, accompanied by smooth muscle hyperplasia. Clinically, it primarily manifests as dysmenorrhea, increased menstrual flow, and uterine enlargement.
