Robotic surgery is increasingly being performed for endometrial cancer. Robotic hysterectomies (RH), like traditional laparoscopic hysterectomies (LH), involve a significant amount of uterine manipulation. The use of a manipulator is though…

Ovarian clear-cell adenocarcinoma (CCA) is known to be a type of cancer in humans with a high frequency of expression of the mammalian target of rapamycin (mTOR), hypoxia-inducible factor-1 (HIF-1), and glucose transporter 1 (Glut1). In thi…

The goal of this study is to evaluate the chromosomal loss in abdominal wall endometriosis by chromogenic in situ hybridization (CISH). Twenty-four cases of abdominal wall endometriosis that developed after cesarean section at the Korea Uni…

Nongastrointestinal-type mucinous borderline tumors have been described as displaying endocervical and serous differentiation and hence have been termed "endocervical-type" mucinous borderline tumors, "mixed-epithelial papillary cystadenoma…

Despite advances in the development of novel methods to improve treatment, ovarian carcinoma is still the leading cause of gynecologic cancer death in the United States and other industrialized nations. Improvements in the clinical outcome …

Patients with low-stage, low-grade endometrial adenocarcinomas have a favorable prognosis; however, a subset has a risk of recurrence and death. We were interested in evaluating patterns of myometrial invasion and correlating them with clin…

Stromal myxoid change is a rare feature of non-neoplastic disease of the uterus. "Myometrial myxoidosis" with secondary myometrial hypertrophy was reported in 2 patients with systemic lupus erythematosus. Uterine myxoid stromal change was a…

Although different histologic subtypes of epithelial ovarian tumors have long been recognized, their molecular abnormalities have not been fully defined. We examined the prevalence of DNA mismatch repair (MMR) protein loss in these tumors. …

We report 2 cases of primary vaginal mucinous adenocarcinoma arising in adenosis in nondiethylstilbestrol-exposed women, 1 with uterus didelphys. Both tumors exhibited morphologic and immunohistochemical features (MUC6 and/or HIK 1083 posit…

The histogenesis of endometriosis and endometriosis-associated ovarian cancer is one of the most mysterious aspects of pathology. To better understand the histogenesis of endometriosis and endometriosis-associated ovarian cancer, we analyze…

Intestinal metaplasia of the endometrium is extremely uncommon with only a single earlier case report. We describe 2 cases of endometrial intestinal metaplasia, one of them involving an endometrial polyp, characterized by the presence of in…

Endometriosis is a chronic disease that affects millions of reproductive-age women. Despite the destructive and invasive nature of endometrioses, most cases are perpetually benign or eventually regress; however, atypical endometriosis is a …

Endometriosis in infancy is most unusual, and associated tumors in this age group are exceptionally rare. We report a case of a serous borderline tumor and endometrial stromal sarcoma arising in an ovarian endometriotic cyst. The patient wa…

The embryonic stem cell self-renewal gene, Nanog, has been shown to be expressed in several tumor types and to regulate tumor development. The aim of this study was to carry out a detailed analysis of Nanog expression in human endometrial a…

This is the case report of a 38-year-old woman who presented with a mass of the right broad ligament that was diagnosed as a female adnexal tumor of probable Wollfian origin (FATWO). The patient was treated with a simple mass excision. Thre…

Uterine adenosarcomas are uncommon mixed Müllerian neoplasms, most commonly arising in the uterine corpus. A new Federation of International Gynecologic Organization staging system for these tumors has recently been implemented. This stagin…

Multicystic mesothelioma was described as a benign neoplasm in most reports. But, whether it is neoplastic or reactive is still controversial. Although multicystic mesothelioma is often accompanied by endometriosis, histologic findings of t…

Gliomatosis peritonei (GP) describes the implantation of mature neuroglial tissue in the peritoneum and is usually associated with mature ovarian teratoma but is also found in cases of immature teratoma. We report the case of a patient with…

Ovarian clear cell carcinoma (CCC) is a unique type of ovarian cancer characterized by distinct clinicopathological and molecular features. CCC is considered to be a highly malignant disease because it is resistant to conventional chemother…

Serous endometrial intraepithelial carcinoma (serous EIC) arising in adenomyosis is rare. It may be underrecognized because of its deceiving morphology when embedded in the foci of adenomyosis. Although there is no connection to peritoneal …

The presence of signet ring cells in a carcinoma within the uterine corpus strongly raises the possibility of a metastasis from a primary tumor in the breast, gastrointestinal tract, or elsewhere. Signet ring cells are extremely rare in pri…
