Cervical myoma is one of the rare types of uterine fibroids with various manifestations ranging from vaginal and pelvic swelling to sexual bleeding, urinary retention and constipation. This report described our experience with a huge cervical tumor in a young nulligravida woman who successfully underwent transvaginal myomectomy. Magnetic resonance imaging (MRI) and CT urography (CTU) were done before operation to assist in diagnosis. After the huge mass was surgically removed, hysteroscopy was carried out to excluding the genital and urinary system malformations. And then, we shaped the rest part of normal cervical tissue through a W-sutured-passway at the point 220.127.116.11 of the cervical canal to tighten the suture and stanch bleeding. Postoperative pathological results suggest that uterine leiomyomas, cervical polyps with extensive squamous metaplasia and nanoscale cyst formation. comprehensively evaluating the condition and improving relevant examinations before operation, distinguishing the surrounding anatomical relationship and selecting appropriate surgical treatment methods are all essential for successful treatment of giant cervical myoma.
