Rare case of endometrial vascular dystrophy: Three case reports.

RATIONALE:Endometrial vascular dystrophy refers to abnormal vessels that are very tortuous, dilated, and sometimes thrombosed. Endometrial vascular dystrophy is rare under hysteroscopy. PATIENT:All three patients had a history of abnormal uterine bleeding. The duration of vaginal bleeding ranged from 1 month to 2 years. There was no history of unusual diseases, alcohol or drug abuse, or genetic history. DIAGNOSES:Endometrial vascular dystrophy. INTERVENTION:Three patients underwent hysteroscopy and curettage under intravenous general anesthesia. Pathological examination showed secretory endometrium, with one case coexisting with endometrial polyps. OUTCOMES:No recurrence was found during postoperative follow-up at 12 months. LESSONS:Endometrial vascular dystrophy is a rare hysteroscopy phenomenon shown in the secretory endometrium. We believe that it was a capillary loop with different manifestations.
