Myomas are the most common type of benign pelvic tumor in women. It is estimated that they occur in 20–25% of women of reproductive ages. The incidence during pregnancy has been found to range from 0.3–2.6%. Myomas seldom cause problems during pregnancy but they do require appropriate evaluation and anticipatory management. The outcome of pregnancies complicated by myomas is directly related to their size and the location of the myoma in relationship to the placental site.
Two case studies are presented of two women who had large myomas. A hysterectomy was required due to persistent postpartum hemorrhage in one, while the other experienced a normal course of labor and delivery.
