OBJECTIVE To determine the frequencies of histopathological findings in endometrial and endocervical biopsy samples with clinical history of Postmenopausal Bleeding (PMB). STUDY DESIGN Descriptive cross-sectional study. PLACE AND DURATION OF STUDY Section of Histopathology, Department of Pathology and Laboratory Medicine, The Aga Khan University Hospital, Karachi, from February 2012 to Janu...
BACKGROUND Unopposed estrogen has a central role in development of endometrial benign, premalignant and malignant lesions. The aim of this study was to evaluate the anti-estrogenic effect of metformin on endometrial histology in comparison with progesterone. MATERIALS AND METHODS A total of 43 patients who were referred to our center for abnormal uterine bleeding and had a histologic diagnosi...
background: endometrial cancer is the most common gynecologic malignancy that has often proceeded by a premalignant phase. modern molecular and immune staining methods for precancerous lesions diagnosis have been expanded. one of the genetic alternations in the endometrial cancer carcinogenesis is the mutational activation of the k-ras oncogene. k-ras mutation has recognized to occur at an earl...
Obesity is linked to increased incidence of endometrioid endometrial cancer (EEC) and complex atypical hyperplasia (CAH). We here explore pattern and sequence of molecular alterations characterizing endometrial carcinogenesis in general and related to body mass index (BMI), to improve diagnostic stratification and treatment strategies. We performed molecular characterization of 729 prospectivel...
Atypical polypoid adenomyoma (APA) is a rare polypoid tumor of the uterus composed of atypical endometrial glands and smooth muscle cells. Concomitant development of endometrial adenocarcinoma in APA remains infrequent. We report a case of the coexistence of endometrioid adenocarcinoma in APA. A 41-year-old patient presented with abnormal genital bleeding. A polypoid mass was extruded from the ...
Background: According to age, history and physical examination findings, there are different diagnoses including anatomic lesions for abnormal uterine bleeding (AUB). In these conditions, hysteroscopy can be performed as a diagnostic and therapeutic procedure. Objective: The aim of this study was defining the diagnostic value of hysteroscopy in evaluating uterine cavity in patients with AUB com...
We examined the aberrant microRNA (miRNA) expression profile responsible for the changes in angiogenesis observed in endometriotic lesions. This study revealed characteristic miRNA expression profiles associated with endometriosis in endometrial tissue and endometriotic lesions from the same patient, and their correlation with the most important angiogenic and fibrinolytic factors. miRNA expres...
OBJECTIVE The study was performed to present the sonographic findings of uterine endometrial stromal sarcoma (ESS). MATERIALS AND METHODS We conducted a retrospective review of sonographic findings of 10 cases that were diagnosed as uterine ESS. The patients' ages ranged from 25 to 51 years (mean age: 36.1 years). The reviews focused on the location, margin, size, number and echotexture of th...
OBJECTIVES The current study examined the KRAS mutation status in a spectrum of mucinous lesions of the uterus, including mucinous metaplasia (MM), atypical mucinous proliferation (AMP), endocervical mucosa, and microglandular hyperplasia (MGH). METHODS Thirty-nine cases, including 15 AMPs, nine MMs, nine MGHs, and six normal endocervical mucosas, were selected from the departmental archive. ...
BACKGROUND Squamous differentiation/squamous metaplasia is often associated with endometrial adenocarcinoma and benign lesions, such as endometrial hyperplasia and chronic endometritis. Morules have distinct histological characteristics, and are referred to as squamous metaplasia or squamoid metaplasia. AIM To focus on the histological characteristics of morules and clarify the difference bet...
