INTRODUCTION It is common for leiomyoma to undergo various secondary changes like hyaline degeneration, cystic change, myxoid degeneration, infection, necrosis, calcification, red degeneration and very rarely ossification. They are said to result from inadequate blood supply resulting in replacement of muscle fibres by hyaline material, collagen, calcium, mucopolysaccharides or a combination of...

Uterine leiomyomas are the commonest benign tumours in women, which estrogen-dependent and grow during reproductive life. Standard treatment for leiomyoma is hysterectomy or myomectomy according to women's age fertility. Prostaglandins particularly PGE1 as misoprostol have an impact on uterine contractions decrease blood loss.

Uterine leiomyomas are benign tumors that can cause pain, bleeding, and infertility in some women. Mediator complex subunit 12 (MED12) exon 2 variants are associated with uterine leiomyomas; however, the causality of MED12 variants, their genetic mode of action, and their role in genomic instability have not been established. Here, we generated a mouse model that conditionally expresses a Med12...

Uterine leiomyomas are the most common benign pelvic tumors in women [1, 2]. They are monoclonal tumors of the smooth muscle cells of the myometrium and consist of large amounts of extracellular matrix that contains collagen, fibronectin and proteoglycan [2, 3]. A thin pseudocapsule that is composed of areolar tissue and compressed muscle fibers usually surrounds the tumors [4]. Leiomyomas may ...

Uterine leiomyomas are a major health problem for women of reproductive age. The molecular biology of these tumors is poorly understood partly because of the lack of relevant animal models. We have produced transgenic mice expressing the simian virus 40 T antigen driven by the promoter of the Calbindin-D9K (CaBP9K) gene and either -1,000 or -117 bp of regulatory sequences so as to establish in ...

OBJECTIVE Although endometriosis and uterine leiomyomas are common conditions, the extent to which either is associated with certain types of malignancies remains uncertain. METHODS Using record linkage techniques, we assessed the relationships between hospital and outpatient admissions for endometriosis or leiomyomas and the development of ovarian and uterine cancers in Denmark between 1978 ...

Secreted frizzled related protein 1 (sFRP1) is a modulator of Wnt signaling. Recently, aberrations of Wnt signaling were reported to be involved in the pathology of various human neoplasms. We investigated the expression and function of sFRP1 in uterine leiomyomas. Secreted FRP1 expression was increased in leiomyomas, compared with normal myometrium using Northern and Western blot analyses. Exp...

Recently multiple cutaneous leiomyomas, uterine leiomyoimatosis and renal cancer have been described as a cancer syndrome with autosomal dominant pattern of inheritance.We report a 79-year-old man who presented with multiple hyperkertotic erythematous nodules on his right leg with histological diagnosis of pilar leiomyoma. In his past medical history several systemic co...

Although benign, uterine leiomyomas occur with high frequency and significant morbidity in reproductive-age women, and they present a significant health problem. Leiomyomas develop in the uterine myometrium and are sensitive to ovarian hormones, making them potential target sites for endocrine disruptors. Here we utilize cell lines derived from rat uterine leiomyomas to determine if a panel of ...
