Abstract

Background: Uterine leiomyoma is the most widespread benign tumor affecting women of childbearing age. There are still gaps in the understanding of its pathogenesis. Telocytes are unique cells found in more than 50 different locations inside the human body. The functional relationship between cells could clarify the pathogenesis of leiomyomata. Examination of membrane receptors on telocytes could explain their role in fibrosis, oxidative stress, and myometrial contractility.

Aim: This research was conducted to assess the density of telocytes in terms of their putative role in leiomyoma formation by focusing on their correlation with the expression of estrogen and progesterone receptors.

Methods: For gross evaluation of uterine tissue samples from leiomyoma, routine histology of adjacent and unaffected myometrium was performed. Immunohistochemical analysis of c-kit, tryptase, CD34, PDGFRα (telocyte-specific), and ER and PRs (estrogen and progesterone receptors) was performed to examine uterine telocytes and the expression of sex steroid receptors.

Results: The decline in telocyte density in leiomyoma foci was correlated with high progesterone expression and low estrogen receptor expression. The unchanged myometrium showed the opposite correlation and balance between both steroid hormone receptors. The difference in sex steroid receptor expression is correlated with the density of uterine telocytes, which emphasizes their conductor function.

Conclusions: A reduction in telocyte density and the changes in examined marker expression demon-strate the involvement of telocytes in local homeostasis. The expression of membrane receptors explicitly indicates their functional potential in the human myometrium, focusing attention on contractility and local homeostasis.

Abstract

Up to 2% of pregnancies may be extrauterine. Despite reproductive problems, they might increase the risk of serious complications. We present a case report of a 31-year-old woman with two extrauterine pregnancies — tubal and ovarian, which occurred at the same side with little time difference. In addition, we aimed to examine possible reasons underlying this rare pathology. Thus, surgically removed tissue specimens were morphologically assessed and further compared with specimens from healthy control patients. Telocytes were analysed in detail due to their pivotal role in the female repro-ductive system. Our study had observational character and obvious limitations typical for a clinical case. Yet, such a clinical case of two ectopic pregnancies has not been previously reported in the literature.
