INTRODUCTION Leiomyoma of the fallopian tube is extremely rare, and its version - leiomyoma cellulare (LC) of the fallopian tube is absolutely unique. Aim of the study was to review literature reports on leiomyomas of the fallopian tubes, and to present cases of leiomyoma and LC of the fallopian tubes in the patients operated on in our ward. MATERIAL AND METHODS There were fewer than 100 case...
Estrogen plays a role in the pathogenesis of leiomyoma. The CYP17 gene codes for the cytochrome P450c17α enzyme, which is involved in the biosynthesis of estrogen. Our aim was to investigate if CYP17 polymorphism could be a useful marker to predict the susceptibility to leiomyoma. Our sample of female subjects was divided into two groups: (1) with leiomyoma (n = 159); (2) without leiomyoma (n =...
Uterine leiomyoma is the most common benign smooth muscle cell tumor of the uterus. Proteomics is a powerful tool for the analysis of complex mixtures of proteins. In our study, we focused on proteins that were upregulated in the leiomyoma compared to the myometrium. Paired samples of eight leiomyomas and adjacent myometrium were obtained and submitted to two-dimensional gel electrophoresis (2-...
The study of uterine leiomyomata (fibroids) provides a unique opportunity to investigate the physiological and molecular determinants of hormone dependent tumor growth and spontaneous tumor regression. We conducted a longitudinal clinical study of premenopausal women with leiomyoma that showed significantly different growth rates between white and black women depending on their age. Growth rate...
Context. Primary leiomyoma of the liver is a rare tumour with uncertain pathogenesis with similar presentation with other tumours of the liver. Little is known about its clinical course. Objectives. To review the literature for case reports of primary leiomyoma of the liver. Methods. Extensive literature search was carried out for case reports of primary leiomyoma of the liver. Results. A total...
Uterine leiomyomas are the most common uterine tumors in women. Estrogen receptor-alpha (ER-alpha) is more highly expressed in uterine leiomyomas than in normal myometrium, suggesting a link between uterine leiomyomas and ER-alpha expression. DNA methylation is an epigenetic mechanism of gene regulation and plays important roles in normal embryonic development and in disease progression includi...
Uterine leiomyoma is the most common tumor of the female genital tract and the leading cause of hysterectomy. Although progesterone stimulates the proliferation of uterine leiomyoma cells, the mechanism of progesterone action is not well understood. We used chromatin immunoprecipitation (ChIP)-cloning approach to identify progesterone receptor (PR) target genes in primary uterine leiomyoma smoo...
Benign metastasizing leiomyoma (BML) is a rare disease that usually occurs in women of reproductive age. They typically have history of uterine leiomyoma treated with hysterectomy. BML can metastasize to distant organs, with the lung being the most common organ. We report two patients who presented with benign metastasizing leiomyoma to the lung. Our first case was a fifty-two-year-old female w...
The distributions of the mRNAs for estrogen receptors (ERα and ERβ) and their binding properties in myometria of pregnant and nonpregnant women and in leiomyoma were studied. RT-PCR analysis indicated that the term pregnancy myometria had little ERα mRNA, whereas the amounts of ERβ mRNAs in pregnant or nonpregnant myometria appeared to be similar. Both ERα and ERβ mRNA were greater in certain l...
Choroidal tuberculomas are present in patients with ocular tuberculosis. They usually occur a patient previous history of tuberculosis, and rarely the initial presentation, no prior systemic manifestations. We unilateral choroidal tuberculoma as presentation presumed which enabled earlier initiation treatment. Unilateral an manifestation tuberculosis: case report
