Endometrial polyps and submucosal fibroids are common causes of abnormal uterine bleeding (AUB) and less commonly infertility. The prevalence of such intrauterine lesions increases with age during the reproductive years, and usually decreases after menopause. The first-line imaging examination in the diagnosis of endometrial polyps as well as submucosal fibroidsis ultrasound, but its accuracy i...

Nucleolar organizer regions (NORs) are loops of DNA that transcribe to ribosomal RNA. They are associated with nonhistone nucleoproteins which can be stained with silver (AgNORs). The present retrospective study was done to study the efficacy of AgNOR technique in differentiating between non neoplastic and neoplastic lesions of endometrium and to assess the relationship between AgNOR counts and...

Modern molecular methods for precancer diagnosis have expanded the range of detectable disease to a preclinical level and provided material for histopathological correlation. The precancer scenario begins with sporadic acquisition of rare PTEN mutation bearing glands, which are morphologically unremarkable, and progresses to discrete foci of cytologically altered glands, readily visible on rout...

PURPOSE Alteration of CyclinD1 was suggested to relate with development of endometrial carcinogenesis before, however CyclinD1 expression is not well defined in endometrial hyperplasia lesions. We checked the relationship between its expression and clinic-pathological variables of endometrial lesions to explore the possibility for CyclinD1 as a potential diagnostic and prognostic marker. METH...

Endometrial serous carcinoma (ESC) is the most aggressive subtype of endometrial cancer. Its aggressive behavior and poor clinical outcome may be partially attributed to lack of early diagnostic markers and unclear patho-genesis. The transcription factor Erythroid-E2-related factor 2 (Nrf2) is a recently identified protein marker, which plays a role in carcinogenesis as well as responsible for ...

INTRODUCTION Endometrial hyperplasia represents a diversified set of disorders which has challenged pathologists for decades. Due to its high likelihood of progression to carcinoma, endometrial intraepithelial neoplasia (EIN) demands prompt and specialized intervention. MATERIALS AND METHODS This 15-month (September 2014 - November 2015) retrospective analysis involved 258 cases of female pat...

Endometrial hyperplasia (EH) is a pathological condition characterised by hyperplastic changes in endometrial glandular and stromal structures lining the uterine cavity. Endometrial hyperplasia, particularly with atypia, is a significant clinical concern because it can be a precursor of endometrial cancer. Accurate diagnosis of precancerous lesions of the endometrium and exclusion of coexisting...

OBJECTIVES To observe the differential expression of phophatase and tensin homologue in normal proliferative, hyperplastic and malignant endometrial lesions. METHODS .The retrospective study was based on the analysis of endometrial samples, both hysterectomies and curettage, received at the department of pathology Basic Medical Sciences Institute at the Jinnah Postgraduate Medical Centre, Kar...

BACKGROUND Endometrial cancer incidence is continuing to rise in the wake of the current ageing and obesity epidemics. Much of the risk for endometrial cancer development is influenced by the environment and lifestyle. Accumulating evidence suggests that the epigenome serves as the interface between the genome and the environment and that hypermethylation of stem cell polycomb group target gene...

Study of AgNOR has been identified as a reliable indicator of cell proliferation and in turn, allows a clear distinction between benign, premalignant, and malignant epithelial changes. The aim of this study was to analyze and evaluate the application of AgNOR method as diagnostic tool in non-neoplastic and neoplastic lesions of endometrium. The study included evaluation of AgNOR staining on a t...
