Background and Objective: For nearly a century, it has been suspected that reproductive tract infections play an etiologic role in uterine leiomyoma. However, no epidemiologic study of leiomyoma has used the polymerase chain reaction (PCR) to compare uterine tissues from cases and non-cases, and to investigate associations between uterine leiomyoma and infections detected by PC...

Uterine leiomyoma is the most common benign tumor of genital tract. The etiology of myomas is unknown. Leiomyoma shows a broad spectrum of radiographic appearances depending on the number, size, and location of the tumor. The diagnostic method for uterine leiomyomas is based primarily on the clinical situation. Despite of the varied diagnostic options such as; transvaginal sonography, sonohyste...

OBJECTIVE Uterine leiomyomas are the most common tumor of the uterus. But the molecular causes of uterine leiomyoma remain unclear. We conducted the current investigation in order to elucidate the molecular mechanisms in the development of uterine leiomyoma. METHODS We employed a new and accurate reverse transcription-polymerase chain reaction (RT-PCR) method that involved annealing control p...

Benign metastasizing leiomyoma (BML) is composed of well-differentiated smooth muscle cells and dense connective tissue. BML affects middle-aged women who have had previous hysterectomies due to a histologically benign-appearing uterine leiomyoma. We report here on a case of BML from the uterine leiomyoma in a 39-year-old woman that involved the soft tissues, skeletal muscles, lungs and breasts...

background: uterine leiomyoma (ul) is a benign tumor of uterine smooth muscle that affects women in reproductive ages. fas has an important role in initial stages of apoptosis. previous studies have shown an association between the fas gene and tumorigenesis. in the present study, we evaluated the relationship between fas a-670g (rs 1800682) and ul risk. methods: the fas gene polymorphism of 15...

The molecular mechanism of the cell-cycle machinery in uterine leiomyoma has not yet been fully elucidated. Among the various types of cell-cycle regulators, p27(Kip1) (p27) is considered to be a potent tumor suppressor. To provide further molecular basis for understanding the progression of uterine leiomyoma, our objective was to evaluate the expression level of p27 in normal myometrium and ut...

INTRODUCTION Leiomyoma of the bladder is a rare tumor arising from the submucosa. Most patients with bladder leiomyoma may present with urinary frequency or obstructive urinary symptoms. However, there are a few cases of bladder leiomyoma coexisting with uterine leiomyoma presenting as dyspareunia. We herein report an unusual case of coexisting bladder leiomyoma and uterine leiomyoma presenting...

The association of uterine leiomyoma with increased risk of breast cancer is controversial. Therefore, we used the National Health Insurance Research Database of Taiwan to examine breast cancer incidence and mortality among Asian patients with and without uterine leiomyoma. We compared breast cancer incidence and mortality between 22,001 newly diagnosed uterine leiomyoma patients and 85,356 ind...

OBJECTIVES To investigate the effect of phenolic environmental estrogens on uterine leiomyoma from the perspective of clinical epidemiology. METHODS Urine and blood samples were collected from Han women with uterine leiomyoma and women without uterine leiomyoma, living in Nanjing, China, between September 2011 and February 2013. A total of 156 urine samples and 214 blood samples were collecte...

AIM The present study was undertaken to explore the relationship between environmental exposure and risk of uterine leiomyoma in women using an epidemiologic survey. SUBJECTS AND METHODS We conducted a case-control survey of premenopausal Han women aged 30-50 years in Nanjing. The subjects included 600 patients with uterine leiomyoma confirmed at the Affiliated Zhongda Hospital of Southeast U...
