INTRODUCTION: Endometriosis is a common benign gynecological condition that can be associated with a slightly increased risk of developing a wide range of malignancies. CASE PRESENTATION: We herein report a singular case of a 62-year-old w…

OBJECTIVES: To describe sonographic features of the microcystic elongated and fragmented (MELF) pattern of myometrial invasion (MI) using the International Endometrial Tumor Analysis (IETA) criteria; to assess the effect of the MELF pattern…

BACKGROUND: The aim of this study was to assess the agreement rate between intraoperative evaluation (IOE) and final diagnosis (FD) in a series of surgically resected endometrial carcinoma (EC), with a preoperative ambiguous or inconclusive…

BACKGROUND: We reviewed published cases of uterus-like mass (U-LM), endomyometriosis, polypoid adenomyoma (PA), adenomyomatous polyp, atypical PA (APA), and adenomyoma. SEARCH METHODS: PubMed, Medline, and Scopus searches of all cases publ…

OBJECTIVE: To describe the clinical and ultrasound characteristics of ovarian pure clear cell carcinoma. METHODS: This was a retrospective study involving data from 11 ultrasound centers. From the International Ovarian Tumor Analysis (IOTA…

STUDY OBJECTIVE: To evaluate near-infrared radiation imaging with intravenous indocyanine green (NIR-ICG) during laparoscopic intervention to identify endometriosis lesions. DESIGN: A single-center, prospective, single-arm pilot study (Can…

To describe sonographic features of the microcystic elongated and fragmented (MELF) pattern of myometrial invasion (MI) using the International Endometrial Tumor Analysis (IETA) criteria; to assess the effect of the MELF pattern on preopera…

Class III β-tubulin (TUBB3) overexpression in ovarian cancer (OC) associates with poor prognosis. We investigated whether TUBB3 overexpression elicited anti-TUBB3 antibody production in OC patients and whether these antibodies may have diag…

Uterine perivascular epithelioid cell tumors (PEComas) are rare neoplasms that may show overlapping morphology and immunohistochemistry with uterine smooth muscle tumors. In this study, we evaluated the morphologic, immunohistochemical, and…

Ovarian clear cell carcinoma (OCCC) is a subtype of epithelial ovarian cancer with characteristic biological features and aggressive clinical behavior. OCCCs show a pattern of gene mutations different from other type I ovarian malignancies,…

Case Report We report a case of bowel endometriosis complicated by spontaneous hemoperitoneum and miscarriage in a 33-year-old primigravida at the 24 th week of gestation. An emergency laparotomy showed spontaneous rupture of the left uteri…

OBJECTIVE: To verify whether the capability of magnetic resonance imaging (MRI) in diagnosing deep infiltrating colorectal endometriosis (DICE) is improved using an association of MRI findings. METHODS AND MATERIALS: The imaging database o…

OBJECTIVE: To identify a possible marker of follicular depletion in relation to some histologic parameters of endometriotic cysts. DESIGN: Prospective study. SETTING: Università Cattolica del Sacro Cuore, Operative Division of Endocrinolo…

Introduction: Endometriosis, defined as the growth of endometrial tissue outside \nthe uterine cavity is a common gynaecological disorder affecting 10-15% \nof women in their reproductive years. It is a major clinical problem causing in- \n…

Glassy cell carcinomas are composed of malignant cells showing a "ground glass" cytoplasm, distinct cell membranes, and large nuclei with prominent nucleoli. To our knowledge, only 12 cases of glassy cell endometrial carcinomas (EGCC) have …

OBJECTIVE: To report on a patient with endomyometrioma with atypias and to review the literature. DESIGN: Case report and literature review. SETTING: Clinical and pathologic. PATIENT(S): A 33-year-old nulliparous woman with right flank p…

BACKGROUND: Endometrial ossification is a rare disease. More than 80% of cases occur after pregnancy, but it has been observed in patients with a history of endometritis, dilation and curettage, and metabolic disorders. CASE: A 42-year-old…

The discovery of an ovarian mass during pregnancy is often a difficult issue because of the risk related to surgical intervention during pregnancy. Moreover, ultrasound examination is often unable to provide a definitive diagnosis. A case o…

Endometriosis is a common gynecologic disease, which generally follows a benign course. Notwithstanding, several clinical and histologic studies as well as molecular data show that endometriosis could be a precursor of sporadic endometrioid…
