High levels of CA-125 in a case of a parasitic leiomyoma presenting as an abdominal mass.

A 32-year-old woman presented with increasing abdominal girth and discomfort secondary to a 18-week-size mass and a CA-125 level of 1539. She underwent an exploratory laparotomy and resection of a parasitic fibroid following which the CA-125 levels decreased and normalized within a month. A review of English literature indicates that association of raised CA-125 levels with fibroids is inconsistent and very modest and such high levels have not been previously reported.
