Abstract
INTRODUCTION AND IMPORTANCE: Uterine fibroids, benign tumors of the myometrium, can cause pelvic pain. Obesity and diabetes mellitus can increase the risk of developing fibroid. We present two cases of uterine fibroid, diabetes mellitus, and obesity with moderate-to-severe chronic pain. CASE PRESENTATION: The first case is a 37-year-old woman with pelvic pain and a subserosal uterine fibroid, primary infertility, grade 2 obesity, and diabetes mellitus. Pathologic examination revealed smooth muscle cells with degeneration sites. The second case is a 35-year-old nulliparous woman with abdominal enlargement, lower abdominal pain, diabetes mellitus, and morbid obesity. Ultrasonography showed a large uterus with a hyperechoic mass and cystic degeneration. Histopathological examination revealed leiomyoma. CLINICAL DISCUSSION: Our patient's chronic pelvic pain may be caused by its large size. Excess adipose tissue in obesity may result in the formation of estrone, causing the proliferation of fibroids. A subserous fibroid is less likely to cause infertility; thus, a myomectomy was performed to relieve pain. Obesity and diabetes could interfere with patients' periods. Higher levels of insulin and fat tissue induce androgen production. Increased estrogen levels lead to alteration of gonadotropin production, menstrual abnormalities, and ovulatory dysfunction. CONCLUSION: Cystic degeneration of the subserous uterine fibroid could induce pain though it rarely affects fertility. A myomectomy was conducted to relieve pain. Comorbid diseases such as diabetes mellitus and obesity can lead to cystic degeneration of the uterine fibroid.
