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...

Uterine artery embolization (UAE) has gained traction as a safe and effective treatment modality for symptomatic uterine leiomyomata since its introduction nearly two decades ago. This review includes an overview of current concepts with regard to patient selection, technique, and outcomes following UAE. Specific topics also include the impact of this procedure on fertility and pregnancy, the emerging role of UAE in the treatment of adenomyosis, and how UAE compares with surgical intervention for the treatment of symptomatic leiomyomata...

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...

Achondroplasia is an autosomal dominant disease which is characterized by limb shortening and narrow trunk, and macrocephaly. Women with achondroplasia suffer from infertility, menorrhagia, dysmenorrhoea, leiomyomata and early menopause. Our case was a 26-year-old woman with achondroplasia who had scoliosis and osteoporosis. She referred to our clinic at 9 weeks of gestation and had all screenings completely. She had a single female fetus with no abnormalities. She had an emergent due to rupture of membranes at 37 weeks and 3 days under general anesthesia...

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...

OBJECTIVE: Intravenous/intravascular leiomyomatosis is characterized by intravenous proliferation of a histologically benign smooth muscle cell tumor mass that is non-tissue-invasive. Although benign, intravenous leiomyomatosis may cause remarkable systematic complications, presents significant diagnostic difficulties, and also is characterized by a relatively increased possibility of recurrence. We determine patients' characteristics, and recurrence and treatment of intravenous leiomyomatosis...

This review discusses the current state of our understanding regarding the genetic basis of the most important reproductive disorders in women. For clarity, these disorders have been divided into eugonadal and hypogonadal types. Hypogonadal disorders have been further subdivided according to serum gonadotropin levels. Our review focuses on historical and recent data regarding the genetics of the hypothalamic-pituitary-gonadal axis dysfunction, as well as the development and etiology of eugonadal disorders including leiomyomata, endometriosis, spontaneous ovarian hyperstimulation syndrome, polycystic ovarian syndrome, mullerian aplasia, and steroid hormone resistance syndromes...

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...

Leiomyoma is the most common tumor seen affecting women mostly of reproductive age groups. It is composed of smooth muscle cells that are positive for smooth muscle actin on immunohistochemistry. Leiomyomata peritonealis disseminata (LPD) is characterized by nodules that stud the peritoneum. It is seen in association with hormone-producing ovarian tumors and coexisting leiomyomas of the uterus. Association with mesenteric leiomyomas has been reported. Ovarian leiomyomas are very rare tumors of the ovary and coexisting LPD with ovarian leiomyomas has not been reported before...

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. CASE: We present the case of an 83-year-old female with postmenopausal bleeding who underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy for clinically atypical appearing leiomyomata...

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...

Leiomyoma of deep soft tissue is an unusual entity reported in less than 60 cases in the English literature. The lesion is now accepted as a rare neoplasm. Leiomyomata of deep soft tissue have been divided into 2 groups, those occurring primarily in women in the retroperitoneum, histologically similar to leiomyomata of the uterus, and those occurring equally in both sexes in the somatic deep soft tissues. Irrespective of location, these lesions can demonstrate calcification, and even less commonly ossification...

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...
