We conducted a meta-analysis to examine p16INK4a expression in uterine smooth muscle tumors (USMTs). Although the prognostic value of tumor suppressor p16INK4a has been elucidated in a variety of cancers and precancerous lesions, its role in USMTs is not well established. We searched PubMed, Web of Science, and Embase for publication son p16INK4a expression in USMTs. Strict inclusion and exclusion criteria were imposed. Risk ratios (RRs) with 95% confidence intervals (95%CIs) were calculated to assess the strength of association...

Hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome is a rare genetic disorder that predisposes individuals to multiple cutaneous leiomyomas, renal cell carcinomas, and in women, uterine leiomyomas. Also known as Reed syndrome, it is caused by a germline heterozygous mutation of the fumarate hydratase tumor suppressor gene. HLRCC is associated with significant morbidity because of pain from cutaneous and uterine leiomyomas, the cutaneous pain often of unique character. Although genetic testing is currently considered the criterion standard to diagnose HLRCC, newer immunohistochemistry markers may provide rapid and cost effective alternatives to genetic testing...

CONTEXT AND OBJECTIVE: Uterine fibroids (UF), also known as leiomyomas, are the most prevalent gynecological tumors. The Uterine Fibroid Symptoms and Quality of Life (UFS-QOL) is the only specific questionnaire that assesses symptom intensity and quality-of-life issues for women with symptomatic UF; however, it only exists in the English language. Thus, we aimed to translate and culturally validate the UFS-QOL questionnaire for the Brazilian Portuguese language. DESIGN AND SETTING: Cross-sectional study, Department of Gynecology and Obstetrics, FMRP-USP...

Uterine leiomyomas are the most common benign smooth muscle cell tumors in women. Estrogen (E2), progesterone (P4) and environmental factors play important roles in the development of these tumors. New treatments, such as mifepristone, have been proposed. We evaluated the gene expression of total (PRT) and B (PRB) progesterone receptors, and the histone acetyltransferase (HAT) and deacetylase (HDAC) activity after treatment with E2, P4 and mifepristone (RU486) in primary cell cultures from uterine leiomyoma and normal myometrium...

We addressed uncertainties regarding Hereditary Leiomyomatosis and Renal Cell Carcinoma (HLRCC) by exploring all French cases, representing the largest series to date. Fumarate Hydratase (FH) germline testing was performed with Sanger sequencing and qPCR/MLPA. Enzyme activity was measured when necessary. We carried out whenever possible a pathology review of RCC and S-(2-succino)-cysteine (2SC)/fumarate hydratase immunohistochemistry. We estimated survival using non-parametric Kaplan-Meier. There were 182 cases from 114 families...

Benign metastasizing leiomyoma (BML) is a rare condition in which a benign uterine leiomyoma causes metastasis, mainly to the lungs. The patient was a 72-year-old woman who had undergone hysterectomy for an uterine leiomyoma at 37 years of age. Between the ages of 52 and 68 years, she had undergone 5 metastatectomies for 10 BMLs. At the current presentation, 2 nodules located in the right upper lobe of the lung were resected. The histological diagnosis was BML, and immunohistochemical staining demonstrated that the tumor cells were positive for estrogen and progesterone receptors...

Uterine leiomyomas (ULM) are a common cause of solid pelvic tumors in women. Their etiopathogenesis remains unclear. Interleukins (ILs) and their receptors can influence tumor biology of ULM. The aim of this study was to evaluate single nucleotide polymorphisms (SNPs) exhibited in the genes IL4 (rs2070874), IL4R (rs1801275), IL12RB1 (rs11575934), IL12B (rs6887695), IL13 (rs20541) and IL23R (rs7517847) as risk factors for ULM in Slovenian women and to identify associations between corresponding clinical parameters and the analyzed SNPs...

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is caused by germline mutations in the FH gene, and is associated with increased incidence of leiomyomas and a potentially aggressive variant of renal cell carcinoma (HLRCC-associated RCC). Absent immunohistochemical expression of fumarate hydratase (FH) has previously been used to diagnose HLRCC-associated RCC, but immunohistochemical staining of leiomyomas is not standard practice. We performed immunohistochemistry (IHC) on whole sections from consecutive cutaneous leiomyomas from our archives to evaluate for both FH and succinate dehydrogenase B expression, in addition to clinicopathologic data collection and review of all hematoxylin and eosin-stained slides for blinded morphologic evaluation of features reported to be seen in HLRCC-associated uterine leiomyomas...

BACKGROUND: Although leiomyomas are the most common gynecologic disorders, non-puerperal uterine inversion due to leiomyoma is considered as a rare clinical problem. This condition can occur as a complication of a large sub-mucous leiomyoma that leads to dilate cervix and protrude into vagina. The patient may have several symptoms such as heavy vaginal bleeding, pelvic pain and intermittent acute urinary retention. CASE: We presented a 32-year-old nulliparous woman with 17 years of unexplained infertility and diagnosis of a large vaginal prolapsed non-pedunculated leiomyoma...

Uterine fibroids, also known as uterine leiomyoma (UL), are monoclonal tumors of the smooth muscle tissue layer (myometrium) of the uterus. Although ULs are considered benign, uterine fibroids are the source of major quality-of-life issues for approximately 25% of all women, who suffer from clinically significant symptoms of UL. Despite the prevalence of UL, there is no treatment option for UL which is long term, cost-effective, and leaves fertility intact. The lack of understanding about the etiology of UL contributes to the scarcity of medical therapies available...

Dobrosława Sikora-Szczęśniak
Parauterine location of leiomyomas is observed to be an extremely rare clinical condition. However, when benign or malignant primary tumours are detected in that area, they are often found in the Retzius space. There have been only six cases of leiomyomas in the Retzius space reported in the literature so far. The paper presents one such leiomyoma case located in the Retzius space. This extremely rare location of the tumour justifies its presentation. The medical records of the patient treated in the outpatient's obstetrics and gynaecology (ob-gyn) clinic, her case history, and hospital records, supplemented by information obtained from the patient's daughter, were analysed...

Włodzimierz Baranowski
Uterine myomas (fibromas, leiomyomas) are the most common tumours in women, and their clinical signs and symptoms are presented by 25-40% of patients with these benign tumours. According to current guidelines, the armamentarium for myoma management consists of: medical therapy (GnRH, SPRMs), non-surgical alternatives including uterine artery embolisation (UAE), vaginal temporary occlusion of uterine arteries using clamp-like device or MRgFUS technique, and surgical treatment (including minimally invasive techniques)...
