OBJECTIVES The aim of the study was to evaluate the prevalence of cellular leiomyomas and partially cellular leiomyomas in postoperative samples. MATERIAL AND METHODS A total of 2144 cases of uterine leiomyomas were diagnosed in postoperative samples at the Department of Obstetrics and Gynecology, RSzS, Radom, Poland, between 1998 and 2014. We analyzed 384 cases which were subdivided into 4 g...

BACKGROUND The pathogenesis of uterine leiomyomas, the most common benign tumor in women, remains unclear. Since acquired factors such as obesity, hypertension and early menarche place women at greater risk for uterine leiomyomas, uterine leiomyomas may be associated with epigenetic abnormalities that are caused by unfavorable environmental exposures. PRINCIPAL FINDINGS Profiles of genome-wid...

Oral leiomyoma is a benign smooth muscle tumor that occurs most frequently in the uterine myometrium, gastrointestinal tract, and skin. Incidence in the oral cavity is considered uncommon. Most cases are reported in adults, with very few cases described in children. A rare case of multiple leiomyomas localized on the tongue, cheek, and floor of the mouth of an 8-month-old baby is reported. The ...

Sarcoidosis (Besnier-Boeck-Schaumann disease) is a multisystem disease of unknown etiology with various cutaneous presentations. It is characterized by the presence of non-caseating ‘naked’ granulomas in the affected tissue. We report a case of polymorphic cutaneous sarcoid in a 39-year-old immunocompetent male. He was visited at our outpatient department with multiple asymptomatic red colored ...

OBJECTIVE To examine the ultrastructural characteristics of extracellular matrix and mature collagen fibrils in uterine leiomyomas and compare them with those in adjacent normal myometrium. DESIGN Analysis of paired leiomyoma-myometrium in surgical specimens. SETTING Research center and tertiary care center. SUBJECT(S) Women undergoing medically indicated hysterectomy for symptomatic uter...

OBJECTIVE In an attempt to clarify the clonality and genetic relationships that are involved in the tumorigenesis of uterine leiomyomas, we used a total of 43 multiple leiomyomas from 14 patients and analyzed the allelic status with 15 microsatellite markers and X chromosome inactivation analysis. STUDY DESIGN We have used a set of 15 microsatellite polymorphism markers mapped on 3q, 7p, 11, ...

The X-linked enzyme, glucose-6-phosphate dehydrogenase (G-6-PD) was used as a cellular marker to study the clonal characteristics of human atherosclerotic lesions from females heterozygous for G-6-PD isoenzymes. Portions of uninvolved aortic wall contained both isoenzyme types (A and B), and their isoehzyme patterns were used to establish criteria for polyclonal lesions. Portions of uterine lei...
