Abstract Leiomyomas, adenomyosis, and endometriosis are reported to be risk factors for endometrial carcinoma (EC), and adenomyosis and endometriosis also for ovarian carcinoma (OC). We aimed to describe the prevalence of these conditions i…

This article reviews the most relevant pathological and molecular features of ovarian tumours that are associated with endometriosis. Endometriosis is a common condition, affecting 5-15% of all women, and it has been estimated that 0.5-1% o…

AIMS: To compare clinicopathological and immunohistochemical features of polypoid endometriosis (PE) and non-polypoid endometriosis (NPE). METHODS AND RESULTS: Fifteen cases of PE and 20 cases of NPE were assessed. All cases were stained im…

The levonorgestrel-releasing intrauterine system (L-IUS) is widely used in contraception and in the treatment of menorrhagia, dysmenorrhea, adenomyosis, and endometriosis. L-IUS is also increasingly considered in the management of endometri…

AIMS: The significance and pathogenesis of irregular or asynchronous maturation within endometrial glands remains uncertain. The aim of this study was to investigate differences in epithelial hormone receptor immunoreactivity and stromal ce…

AimsThe relationship between endometriosis and ovarian endometrioid adenocarcinoma (OEC) is well recognised but it is unclear whether endometriosis positive and negative OECs develop via similar pathogenetic mechanisms.MaterialsSixty-seven …

Laparoscopy is currently considered to be the gold standard investigation in patients suspected to have endometriosis, but this is an invasive and relatively costly procedure and there may be significant delays in diagnosis. As the eutopic …

Adenomyomas are circumscribed tumorlike masses most often involving the uterus and consisting of endometrioid glands, stroma, and smooth muscle tissue. They are uncommon in extrauterine sites and in this situation it may be unclear whether …

AimsTo determine how frequently endometrioid ovarian carcinomas (EOC) express WT1 protein, and to correlate the results with the presence of endometriosis and p53 immunoreactivity.MethodsForty-one grade 1-2 EOC were stained immunohistochemi…

AIMS: To describe a patient in whom multiple endometrial biopsies revealed stromal proliferative lesions causing diagnostic difficulty. METHODS AND RESULTS: A 39-year-old woman with a history of menorrhagia and dysmenorrhoea underwent two e…
