摘      要：A 46-year old woman (gravida 3, para 1) presented at West China Second Hospital with complaints of a space-occupying lesion in the uterus that, 2 years before, had been diagnosed as a uterine cyst at West China Second Hospital. On that previous occasion, B-ultrasonography revealed a cystic mass with a compartmentalized structure (10.3 × 5.4 × 8.8 cm) on the left side of the pelvic cavity, and laparoscopic exploration found a cystic mass on the posterior uterine wall, which was diagnosed as leiomyoma with cystic degeneration based on pathology analysis of flash-frozen surgical tissues. Laparoscopic myomectomy was performed, and pathology analysis of paraffin-embedded tissue confirmed leiomyoma with degeneration. Immunohistochemistry showed the lesion to be positive for caldesmon but negative for CD10. Rate of Ki67 positivity was less than 1%, indicating a benign lesion. The woman recovered well after the operation. Follow-up ultrasonography at 3 months after surgery identified a uterine cystic mass of 3.0 × 2.5 × 1.7 cm.
