Abstract

Cotyledonoid dissecting leiomyoma (CDL), also termed Sternberg tumor, is a variant of uterine leiomyoma that is rarely diagnosed by clinical evaluation. At present, ~43 cases of CDL have been reported in the literature written in the English language. Due to the distinctive grapelike gross appearance of an exophytic mass resembles placental tissue, CDL is often misdiagnosed clinically as an ovarian tumor or uterine sarcoma. Therefore, an awareness of the features of the disease is important to prevent misdiagnosis and overtreatment. The present study reports 4 cases of CDL of the uterus that were treated at the Second Hospital of Jilin University between January 2009 and December 2011. All 4 patients in the current study presented with a palpable asymptomatic pelvic mass, which was detected during physical examinations, and cancer antigen 125 tumor marker levels that were within the normal range. The exploratory laparotomy of the 4 patients revealed lobulated tumors with a grapelike appearance extending from the lateral uterine wall into the ligament or the adjacent tissues. The frozen section and postoperative pathology were diagnosed as CDL. A total abdominal hysterectomy was performed in the first case of a 55‑year‑old woman that had been in menopause for 7 years. The patient was well and showed no evidence of disease subsequent to 48 months of follow‑up. A total abdominal hysterectomy and right salpingo‑oophorectomy were performed in the second case of a 43‑year‑old woman, who was well and showed no evidence of disease subsequent to 26 months of follow‑up. A subtotal abdominal hysterectomy and bilateral salpingectomy were performed in the third case of a 37‑year‑old woman, who was well and showed no evidence of disease subsequent to 27 months of follow‑up. A total abdominal hysterectomy and right‑salpingectomy were performed with the removal of a retroperitoneal fibroid extension in the fourth case of a 48‑year‑old woman, who was well and showed no evidence of disease subsequent to 32 months of follow-up.
