Clinical features of myomas

Abstract

Uterine myomas are the most common solid pelvic tumors in women and the primary indication for hysterectomy. Most of the myomas are asymptomatic. The most common symptoms associated with uterine myomas are abnormal uterine bleeding and pelvic discomfort mostly caused by the mass effect. Vaginal bleeding may lead to iron deficiency anemia. Uterine myomas have a significant role in reproductive dysfunction, although a causal relationship between infertility and intramural or subserosal myomas not disturbing the uterine cavity has not been established clearly. Nevertheless myomas, especially the tumors distorting the uterine cavity, are associated with infertility and spontaneous miscarriage. In addition, the myomas may be the potential cause for numerous obstetric complications, especially if they are located adjacent to placenta. The transformation of myomas to leiomyosarcomas is a very rare event. Leiomyosarcomas may be suspected in postmenopausal women with rapidly growing symptomatic solid pelvic mass. Despite the high prevalence of these tumors, there is paucity of data available regarding the natural clinical history of myomas.
