endometrial polyp
Benign overgrowth of endometrial tissue that projects into the uterine cavity, often causing abnormal bleeding.
Full Definition
An endometrial polyp is a benign growth arising from the endometrial lining that extends into the uterine cavity. These polyps consist of endometrial glands and stroma and may be sessile or pedunculated. They commonly present with abnormal uterine bleeding, including intermenstrual bleeding, menorrhagia, or postmenopausal bleeding. Risk factors include age, obesity, hypertension, and tamoxifen use. Diagnosis is typically made through transvaginal ultrasound, sonohysterography, or hysteroscopy. While most polyps are benign, there is a small risk of malignant transformation, particularly in postmenopausal women. Treatment usually involves hysteroscopic polypectomy, especially when symptomatic or when malignancy cannot be excluded.
