Uterine leiomyomata are the most common benign tumors of the gynecologic tract impacting up to 80% of women by 50 years of age. It is well established that these tumors are the leading cause for hysterectomy with an estimated total financial burden greater than $30 billion per year in the United States. However, for the woman who desires future fertility or is a poor surgical candidate, definitive management with hysterectomy is not an optimal management plan. Typical gynecologic symptoms of leiomyoma include infertility, abnormal uterine bleeding (AUB)/heavy menstrual bleeding (HMB) and/or intermenstrual bleeding (IMB) with resulting iron-deficiency anemia, pelvic pressure and pain, urinary incontinence, and dysmenorrhea...

BACKGROUND: MicroRNAs (MiR) may promote fibroid development via altered expression of genes involved in cell proliferation and ECM formation, and evidence supports aberrant expression of MicroRNA (MiR) 21a-5p in fibroids. The purpose of this study was to investigate the functional significance of MiR 21a-5p overexpression in the pathobiology of leiomyomata (fibroids). METHODS: A basic science experimental design using immortalized fibroid and myometrial cell lines derived from patient-matched specimens was used...

Black women are disproportionately affected by uterine leiomyomata (UL), or fibroids, compared to other racial groups, having a greater lifetime risk of developing UL and an earlier age of diagnosis. In order to elucidate molecular and genetic mechanisms responsible for the increased prevalence and morbidity associated with UL in black women, clinical, pathologic, cytogenetic, and select molecular profiling (MED12 mutation analysis) of 75 self-reported black women undergoing surgical treatment for UL was performed...

We evaluated the efficacy of gonadotropin-releasing hormone agonist (GnRHa) therapy for improving the myometrial thickness in women with thin (less than 1 cm) uterine walls, a contraindication for microwave endometrial ablation (MEA). The normal myometrium thickness was 0.5 cm, 0.7 cm and 0.9 cm. After the third GnRHa dose, the myometrial thickness increased to over 1 cm in all the three patients, and all were able to undergo MEA. The VAS score for menorrhagia improved in all the cases. The patient satisfaction levels were 10 in 2 of the 3 patients, and 5 in the other...

INTRODUCTION: Intravenous extension of benign uterine leiomyomata ('fibroids'), in the absence of discrete metastatic disease has rarely been reported. 'Fibroids' remain one of the most common premenopausal uterine pathologies. METHODS AND RESULTS: We report the diagnosis and multidisciplinary led operative management of a 52-year-old woman with a histologically benign, but biologically aggressive, uterine leiomyoma with intravenous extension to the inferior vena cava (IVC), right heart and pulmonary arteries...

BACKGROUND: Uterine leiomyomas represent the gynecological neoplasm with the highest prevalence worldwide. This apparently benign pathological entity may permeate into the venous system causing the so-called intravenous leiomyomatosis of the uterus (IVL). IVL may seldom extend to large caliber veins and reach the right cardiac chambers or pulmonary arteries and cause signs of right sided congestive heart failure and sudden death. Due to its low incidence, however, IVL with intracardiac extension is often misdiagnosed resulting in deferred treatment...

The aim of the present study was to identify differential pathways in uterine leiomyomata (UL) using a novel method based on protein-protein interaction networks and pathway analysis. The pathway networks were constructed by examining the intersections of the Reactome database and the Search Tool for the Retrieval of Interacting Genes/proteins (STRING) protein-protein interaction (PPI) networks. The Objective network was defined as the differential expressed genes (DEGs) associated with the interactions identified by STRING...

BACKGROUND: Pulmonary benign metastasizing leiomyoma (BML) is a rare disease with a malignant characteristic of spread from the uterus. Most cases are asymptomatic, and only 1% are associated with pneumothorax. CASE REPORT: We present the case of a 42-year-old female with recurrent pneumothoraces leading to an incidental finding of diffuse bilateral pulmonary nodules. The diagnosis of BML was based on the patient's history of uterine leiomyomata and confirmed by a biopsy showing benign smooth muscle staining for desmin and vimentin...

BACKGROUND: Inactivating mutations of CDC73 cause Hyperparathyroidism-Jaw Tumour syndrome (HPT-JT), Familial Isolated Hyperparathyroidism (FIHP) and sporadic parathyroid carcinoma. We conducted CDC73 mutation analysis in an HPT-JT family and confirm carrier status of the proband's daughter. METHODS: The proband had primary hyperparathyroidism (parathyroid carcinoma) and uterine leiomyomata. Her father and daughter had hyperparathyroidism (parathyroid adenoma) but no other manifestations of HPT-JT...

Benign metastasizing leiomyoma (BML) is a rare disease entity typically presenting as multiple extrauterine leiomyomas associated with a uterine leiomyoma. It has been hypothesized that the extrauterine leiomyomata represent distant metastasis of the uterine leiomyoma. To date, the only molecular evidence supporting this hypothesis was derived from clonality analyses based on X-chromosome inactivation assays. Here, we sought to address this issue by examining paired specimens of synchronous pulmonary and uterine leiomyomata from three patients using targeted massively parallel sequencing and molecular inversion probe array analysis for detecting somatic mutations and copy number aberrations...

The GnRH agonistic analogs enable for desensitizing the hypothalamo-pituitary-gonadal axis in malignant and benign conditions where minimizing the production of sex hormones, or blocking ovulation is necessary. The possible indications are prostate cancer, benign prostate hyperplasia, breast cancer, endometriosis, precocious puberty, uterine leiomyomata, assisted reproduction (ART)/in vitro fertilization (IVF), PCOS, minimizing the gonadotoxic effect of chemotherapy in young women, and possibly ovarian cancer...

BACKGROUND: Hereditary leiomyomatosis and renal cell cancer syndrome (HLRCC) is an autosomal dominant syndrome due to mutation in fumarate hydratase. Patients with HLRCC frequently develop cutaneous and uterine leiomyomata and are at risk for renal cell carcinoma. Rarely, other malignancies have been reported. MAIN OBSERVATIONS: We report the development of basal cell carcinoma and melanoma in two siblings with genetically-confirmed HLRCC. CONCLUSIONS: It is unclear whether the development of melanoma and basal cell carcinoma in our patients is due directly to their mutations in the gene encoding fumarate hydratase, or genetic susceptibility at another unrelated locus, or whether these are incidental lesions...

BACKGROUND: Leiomyosarcomas (LMS) and endometrial stromal sarcomas (ESS) may display overlapping histomorphology, which may challenge diagnostic accuracy. Since LMS and ESS have vastly different clinical behavior and adjuvant therapy recommendations, accurate diagnosis is critical.

Uterine leiomyomata present major problem for females. Although they are benign tumors their frequency is associated with many symptoms like infertility, abdominal pain, menorrhagia. Authors based on their own morphological studies and review of the literature try to indicate main factors causing angiogenesis within leiomyomata and its influence on tumor growth. The strongest proangiogenic factor seems to be hypoxia, which stimulates up- and down-regulation of numerous genetically determined substances. Also mechanical pressure acting upon newly growing vessels is one of the factors which may determine formation of so called "vascular pseudocapsule" around the lesion...

BACKGROUND: Primary leiomyoma of the ovary is a rare benign ovarian tumor that only seldom causes acute abdomen. CASE SUMMARY: A 35-year-old gravida 1, para 0 woman presented with a history of acute lower abdominal pain, and 10 weeks of amenorrhea. The patient's physical examination revealed abdominal tenderness, defense, and rebound. On ultrasonographic examination, a solid mass measuring 9.3 × 7.8 cm was detected adjacent to the uterine fundus. The mass was preoperatively diagnosed as a twisted pedunculated subserosal uterine myoma...

We previously demonstrated that berberine (BBR) inhibits cell proliferation and induces apoptosis in a human uterine leiomyoma (UtLM) cell line but does not demonstrate a significant cytotoxic effect in a normal human uterine smooth muscle (UtSM) cell line. However, the mechanisms of this inhibition are unclear. Of note, cyclooxygenase 2 (COX2) and pituitary tumor-transforming gene 1 (PTTG1) are overexpressed in human uterine leiomyomata and are involved in the pathogenesis of uterine fibroids (UFs). We found that COX2 and PTTG1 were overexpressed in UtLM and that BBR decreased COX2 and PTTG1 expression in UtLM cells...

Benign metastasizing leiomyoma is a rare diagnosis in women with history of uterine leiomyomata. Distant metastasis may occur anywhere but is most commonly seen to the lungs. The age of presentation is often young to mid age, with patients often having a history of hysterectomy or myomectomy for uterine leiomyomata. The clinical course of these patients is most often indolent. However, the size and number of nodules can result in pulmonary symptoms. Differentiating benign metastasizing leiomyoma from malignant metastatic disease, including from leiomyosarcoma, is important to avoid unnecessary procedures or delayed treatment...

In a retrospective review, we identified six cases of disseminated peritoneal leiomyomatosis (DPL) that occurred after resection for uterine leiomyoma(ta) using a morcellation procedure between 2010 and 2016. DPL occurred in less than 1% of all patients who underwent a prior hysterectomy with morcellation, and DPL never occurred without having underwent such a resection. The median age of women at the time of their original resection of uterine tissue was 38.6 years; the median time interval until resection of DPL after the primary morcellation procedure was 73 months and the median age was 48 years...
