Typical and atypical clinical presentation of uterine myomas.

Myoma is the most common benign neoplasm that can occur in the female reproductive system, most frequently seen in women in their 50s. Although the majority of myomas are asymptomatic, some patients have symptoms and/or signs of varying degrees. Typical myoma-related symptoms or signs include: (1) menstrual disturbances like menorrhagia, dysmenorrhea and intermenstrual bleeding, (2) pelvic pain unrelated to menstruation, (3) compression symptoms, similar to a sensation of bloatedness, urinary frequency and constipation, (4) subfertility status such as recurrent abortion, preterm labor, dystocia with an increased incidence of Cesarean section, and postpartum hemorrhage, and (5) cosmetic problems due to increased abdominal girth However, there are undoubtedly some clinical presentations secondary to uterine myomas are not so specific, such as: (1) uncommon compression-related symptoms, (2) cardiac symptom and atypical symptoms secondary to vascular involvement or dissemination, (3) abdominal symptoms mimicking pelvic carcinomatosis, (4) dyspnea, (5) pruritus, (6) hiccup or internal bleeding, and (7) vaginal protruding mass or uterine inversion. Familiarization with these symptoms and awareness of other unusual or atypical presentations of uterine myomas will remind clinical practitioners of their significance, and of the necessity of follow-up examinations and individualized management to fit the needs and childbirth desires of the patients.
