Unaware of a large leiomyoma: A case report with respect to unusual symptoms of large leiomyomas

INTRODUCTIONUterine leiomyoma, which arises from uterine smooth muscle, is the most common benign gynecologic tumor of the female pelvis. Clinically, these leiomyomas are diagnosed in approximately 25% of women, the prevalence increases during reproductive age, decreases after menopause, and they are rare in adolescents. In addition to uterine leiomyoma, there are also extrauterine leiomyomas. PRESENTATION OF CASEA 48-year-old multiparous woman visited our outpatient clinic for routine control. She had no symptoms or complaints. Her last health service visit was over 5 years ago, in which she was told that she had a small uterine leiomyoma, which did not require further management. Abdominal examination revealed a large mass extended above the umbilicus, and there was no abdominal tenderness. Abdominal ultrasonography showed a large solid mass occupying the abdomen. Routine laboratory test results were normal, except the hemoglobin level, which was 7.88 g/dl. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. The final diagnosis was a 17-cm, 3985-g intramural, myomatous, cellular leiomyoma that occurred without secondary changes, necrosis, cellular atypia, or mitosis. DISCUSSIONThe most common presenting symptoms of large uterine leiomyomas are abnormal bleeding, dysmenorrhea, pelvic pain, and tumor bulk-related signs. Moreover, there are unusual symptoms or clinical manifestations such as acute edema, thrombosis, ulcer, plethora, calcified pelvic masses, hematometra, severe pulmonary hypertension, and respiratory failure; hence, they can be even life threatening. CONCLUSIONPatients might have no symptoms or might be unaware of the presence of a large uterine leiomyoma, as in our case; however, large leiomyomas have various unusual symptoms in addition to the common ones. These symptoms should not be disregarded or underestimated.
