Abstract

Background

Cotyledonoid dissecting leiomyoma (Sternberg tumor) is a rare variant of the uterine smooth muscle tumor. Although this tumor is a benign tumor clinically and pathologically, the appearance and growth pattern is unusual, so it may be misdiagnosed as malignancy.

Case reports

We report two cases of cotyledonoid dissecting leiomyoma of the uterus that occurred in two 44- and 31-year-old women, respectively. Total hysterectomy and bilateral salpingo-oophorectomy were performed in one of the patients, and myomectomy was done in the other one. Macroscopically, both tumors were grape-like exophytic masses resembling placental tissue. The patients were well after surgery, and one patient gave birth. To our knowledge, this is the first case report of a successful delivery after myomectomy of this tumor.

Conclusion

To prevent aggressive surgery it is important to recognize that this tumor is a benign and unusual appearing variant of leiomyoma. A fertility-sparing surgical procedure should be considered if the patient wishes to preserve her fertility.
