A rare case of endometrial polyp complicated with uterine inversion: A case report and clinical management.

Uterine inversion is a rare disease that is particularly uncommon among non-puerperal women. Herein we reported the only case of uterine inversion known to us that was caused by the endometrial thickening and changes in the polypoid lesion in early puberty. The patient was admitted to our hospital because of massive vaginal bleeding, abdominal pain, and a protruding mass from the vagina. We obtained the patient history by collecting the results of various examinations (including magnetic resonance imaging and color Doppler ultrasound), accurate diagnosis was performed, and a reasonable treatment protocol was developed. She was subjected to laparoscopic uterine-sparing surgery to preserve her fertility. Uterine inversion is a rare disease, and early diagnosis and selection of appropriate treatment options are essential for patients with fertility requirements.
