What condition is characterized by multiple fibroids in the uterus?

The condition characterized by multiple fibroids in the uterus is uterine leiomyomata, also commonly known as uterine fibroids. These are benign tumors that arise from the muscular layer of the uterus and can vary in size and number. Uterine leiomyomata can lead to a range of symptoms, including heavy menstrual bleeding, pelvic pain, and pressure symptoms, depending on their size and location. Understanding this condition is crucial for the management and treatment of patients presenting with related symptoms.

In contrast, uterine hyperplasia involves the thickening of the endometrial lining and is primarily associated with abnormal endometrial growth rather than fibroids. Endometriosis is a condition where endometrial-like tissue grows outside the uterus, causing a different set of symptoms and complications. Polycystic ovary syndrome (PCOS) is an endocrine disorder characterized by ovarian cysts, irregular menstrual cycles, and hormonal imbalances, which is not related to the presence of fibroids in the uterus. Thus, uterine leiomyomata is the defining condition in this context.
