Red degeneration of a large leiomyoma in a non-pregnant woman in pursuit of 17 pregnancies: a case report.

Leiomyoma is a common benign tumor in women of reproductive age. Increasing the number of pregnancy has a significant role in reducing the risk of tumor development. Red degeneration is a rare complication and often occurs during pregnancy. However, its incidence in non-pregnant women is tremendously rare. Herein, we present a case of 51-year-old non-pregnant women with a history of 17 pregnancies, diagnosed with leiomyoma that underwent red degeneration.
