Uterine fibroids are the most common gynecologic benign tumors. Studies supporting a strong pregnancy-related growth of leiomyomas generally claimed a crucial role of sex steroid hormones. However, sex steroids are unlikely the unique actors involved as estrogen and progesterone achieve a pick serum concentration in the last trimester while leiomyomas show a typical increase during the first trimester. Given the rapid exponential raise in serum human Chorionic Gonadotrophin (hCG) at the beginning of gestation, we conducted a review to assess the potential role of hCG in the striking growth of leiomyomas during initial pregnancy...

In a prior randomized controlled study, patients treated with ulipristal acetate (UPA) or placebo for 3 months had a decrease in leiomyoma size. A total of 10 patients' tissue samples (5 placebo and 5 treated with 10 mg/d UPA) that underwent hysterectomy and tissue preservation were identified from this study. Quantitative real-time reverse transcriptase polymerase chain reaction and Western blotting were used to assess fold gene and protein expression of extracellular membrane (ECM) proteins: collagen 1A (COL1A), fibronectin (FN1), and versican (VCAN) of the samples...

PURPOSE: To investigate the potential of diffusion and perfusion indices (ADC and perfusion fraction f) from DWI at 3.0 T in monitoring treatment response to uterine artery embolization (UAE) at 6-month follow-up. METHODS: Twelve female patients with uterine fibroids who underwent 3.0-T pelvic DWI before and 6 months after UAE were included. ADC and perfusion fraction f were calculated from DWI. The Wilcoxon signed-rank test and Spearman rank correlation test were used for statistics...

Pulmonary benign metastasizing leiomyoma (PBML) is a rare disease entity that usually occurs in females of reproductive age with a previous history of uterine myoma. It is typically characterized by multiple pulmonary tumors consisting of benign leiomyoma cells. In the present study, two cases of PBML are discussed. The patient in each case underwent 2-deoxy-2-(fluorine-18)-fluoro-D-glucose positron emission tomography/computed tomography (18-FDG-PET/CT) scans. One patient demonstrated a lack of 18-FDG uptake and a quiescent clinical course...

Prolactin-producing uterine leiomyomas are very rare. Although hyperprolactinemia rapidly improves after removal of such leiomyomas, no preoperative diagnostic test has been established for prolactin-producing uterine leiomyomas. A 45-year-old Japanese woman, gravida 3 para 3, was referred to our hospital for further examination of hyperprolactinemia resistant to a dopamine agonist. A pituitary prolactinoma was undetectable by brain magnetic resonance imaging. A bromocriptine loading test revealed an increased serum prolactin concentration after loading...

The leiomyomas are a common gynecologic entity that may present unusual growth patterns or unusual locations. Its atypical presentations creates a diagnostic challenge. This is a case report of a parasitic leiomyoma located in the anterior abdominal wall in a 53 years old woman with pelvic compressive and urinary symptoms, with no history of any gynecological surgery. This case illustrates the diagnostic difficulties and describes the complementary images used in the preoperative evaluation.

Leiomyoma of urinary bladder is a rare tumour with an incidence of < 0.5% of all the bladder tumours. We report a case of leiomyoma of bladder after taking written and informed consent from a 38 years old female, after obtaining the permission of the institutional review board (IRB). She presented in November 2015, with symptoms of obstructive lower urinary tract for 1 year followed by acute urinary retention. Physical examination was unremarkable. Ultrasound showed well circumscribed polypoidal growth in the bladder with mild hydronephrosis on the left side...

REVIEW

Uterine sarcomas comprise a group of rare tumors with differing tumor biology, natural history and response to treatment. Diagnosis is often made following surgery for presumed benign disease. Currently, preoperative imaging does not reliably distinguish between benign leiomyomas and other malignant pathology. Uterine leiomyosarcoma is the most common sarcoma, but other subtypes include endometrial stromal sarcoma (low grade and high grade), undifferentiated uterine sarcoma and adenosarcoma. Clinical trials have shown no definite survival benefit of adjuvant radiotherapy or chemotherapy and have been hampered by the rarity and heterogeneity of these disease types...

Ulipristal acetate (UPA) is used to treat leiomyomas, and its effect on the endometrium has been studied in biopsy material. Reversible histologic modifications were found, named progesterone receptor modulators-associated endometrial changes (PAEC). However, hysterectomies from patients treated with UPA have not been analyzed. For the first time, we examined surgical specimens from 100 leiomyoma-treated patients for UPA-related endometrial changes. We analyzed the distribution of lesions, involution after treatment, and the relationship between type and extent of lesions and dosage...

Placental neoplasms involving the fetal membranes are exceptionally rare. In leiomyomas and endometrial stromal neoplasms, a uterine origin for nodules in the membranes is also a possibility. We present a case of an incidental endometrial stromal nodule found in the decidua of the free membranes and review the literature.

Cutaneous leiomyomas can be classified into three types according to the site of origin: piloleiomyoma, angioleiomyoma, and dartoic (genital) leiomyoma. It might be expected that leiomyomas are commonly found on the scalp because there are many arrector pili muscles and vessels. However, leiomyomas are actually rarely reported in the scalp. Recently, we observed a case of cutaneous leiomyoma in the scalp and present our experience along with a literature review.

Introduction: It is not uncommon for a woman to suffer from abnormal uterine bleeding (AUB) or heavy menstrual bleeding (HMB) at some point during her lifetime. Once pathology is excluded, in practice, management needs to be individualised, taking into account the improvement of the woman's symptoms and quality of life. Sources of data: Peer-reviewed journals, governmental and professional society publications. Areas of agreement: There is now agreement on a structured, universal approach to the diagnosis of AUB, with the aide memoirs PALM (polyps, adenomyosis, leiomyoma, malignancy) and COEIN (coagulopathies, ovulatory dysfunction, endometrial, iatrogenic, not otherwise classified)...

INTRODUCTION: Acute urinary retention is a rare occurrence in women necessitating further investigation. Potential underlying causes may be broadly classified into obstructive, neurological, pharmacological, and psychogenic categories. CASE: A 36-year-old nulliparous female presented to the Emergency Department with a two-day history of acute urinary retention. Point-of-care ultrasonography and CT scan imaging confirmed the presence of a large uterine mass causing compression of the bladder...

BACKGROUND: Benign metastatic leiomyoma (BML) is an extremely rare disease. Although uterine leiomyomas are benign histologically, they can metastasize to distant sites. While the incidence is very low, the lung is the organ most frequently affected by BML. Pulmonary BML usually presents as numerous well-defined nodules of various sizes, while the cavitary or cystic features in the nodules are rarely observed on radiologic images. CASE PRESENTATION: A 52-year-old woman complained of cough and dyspnea for one month...

Intraparenchymal leiomyoma of the breast are among benign non-epithelial tumors with the lowest incidence. Although it displays a benign histology, it may be confused with malignant lesions and create diagnostic confusion. In this paper, we report a 44-year-old woman with a painless mass with a diameter of 1.5 cm in the upper medial quadrant of her right breast. The lesion was removed surgically. The lesion's histologic examination and immunohistochemical analysis revealed a smooth muscle tumor of the breast...

Neoplasms of the small bowel are rare and comprise only 1-5% of all gastrointestinal neoplasms. The most frequent malignant tumors located in the small bowel are adenocarcinomas, lymphomas and neuroendocrine tumors. Rarely observed are gastrointestinal stromal tumors (GIST), leiomyosarcomas and leiomyomas. Leiomyomas are most frequently seen in the jejunum followed by the ileum and lastly the duodenum. In most cases, a definite diagnosis of these tumors is not possible prior to surgical treatment. The treatment of choice for these tumors is surgery...

PURPOSE: Despite the numerous studies on the factors involved in the genesis and growth of uterine leiomyomas, the pathogenesis of these tumors remains unknown. Intrinsic abnormalities of the myometrium, abnormal myometrial receptors for estrogen, and hormonal changes or altered responses to ischemic damage during the menstrual period may be responsible for the initiation of (epi)genetic changes found in these tumors. Considering these elements, we aimed to offer an overview about epigenetic and genetic landscape of uterine leiomyomas...
