Uterine spindle cell lesions share a dilemmatic overlapped features that needed to be addressed by the pathologist to reach a conclusive accurate diagnosis for its prognostic value and different management decisions. Usage of combined IHC p…

A subset of endometrial endometrioid carcinomas (EECs) with low-grade histology recur with poor outcomes. Published evidence suggests that poor outcomes may be associated with loss of expression of ER-alpha (ER-α) as well as with β-Catenin-…

BACKGROUND AND STUDY AIM: We aim to study the immunohistochemical expression of both hypoxia-inducible factor-1α (HIF-1α) and mammalian target of rapamycin (mTOR) in endometriosis to provide new evidence for a targeted endometriosis therapy…

Intestinal metaplasia (IM) is a rare finding in urinary bladder specimens. It is unclear whether IM without dysplasia is a precursor of malignancy in the urinary system. We retrospectively selected 9 cases of IM of bladder (1 case harboring…

Mesonephric carcinoma is a rare gynecologic neoplasm commonly mistaken for clear cell carcinoma, because of their overlapping morphologic features. Both tumors are negative for estrogen receptor and p16, magnifying this diagnostic dilemma. …

Most available therapies for endometriosis are hormone-based and generally broadly used without taking into consideration the ovarian hormone receptor expression status. This contrasts strikingly with the standard of care for other hormone-…

A 56-year-old G3P3 postmenopausal woman presented with a 5 month history of abnormal uterine bleeding and pelvic pain. A computed tomographic scan revealed a 5 cm right adnexal cystic mass in addition to a thickened, heterogenous endometriu…

Sirtuin 1 (SIRT1), originally identified as a longevity gene, regulates DNA repair and metabolism by deacetylating target proteins such as p53. SIRT1 plays a key role in the pathophysiology of metabolic diseases and neurodegenerative disord…

Signet ring stromal cell tumor (SRSCT) of the ovary is a very rare benign ovarian neoplasm. To date, no underlying genetic mechanism has been identified. In this study, 50 oncogenes and tumor suppressor genes were evaluated for mutations in…

Bone morphogenetic proteins (BMPs) are extracellular, multifunctional growth factors that constitute the largest subset of the transforming growth factor β superfamily. BMP2 is involved in cardiovascular embryogenesis, in addition to a vari…

ObjectiveThe purpose of this study was to evaluate the immunohistochemical Rb2/p130 expression in a series of benign, borderline, and malignant ovarian tumors.Study designSeventy-six operative specimens were analyzed. Frequencies and percen…

Endometriosis is an enigmatic disease of unknown etiology and pathogenesis, which is defined as the presence of endometrial glands and stroma outside the uterus. The most widely accepted theory to explain endometriosis is probably the trans…

Steroidogenic factor-1 (SF-1), a major protein regulating the complex cascade of steroidogenis, has been postulated to play a role in ovarian endometriosis. However, the expression in situ of SF-1 in ovarian endometriosis is unknown. To she…

In this retrospective study on banked tissue, we found that alpha-actinin and talin were completely de-expressed in both endometriosis and endometrioid carcinoma tissue. Some patchy, depolarized labeling for ezrin was noted in the endometri…

The facilitative transport of monosaccharides in human cells is accomplished by a family of transmembrane proteins, GLUT-1 to GLUT-7, that differ in their tissue distribution, affinities for specific monosaccharides, and physiologic regulat…
