New imaging modalities to distinguish rare uterine mesenchymal cancers from benign uterine lesions.

Curr Opin Oncol 2021 Jun 23. Epub 2021 Jun 23.

Department of Radiology. Memorial Sloan Kettering Cancer Center, New York, USA Department of Radiology, Seoul National University College of Medicine, Seoul, Korea Department of Radiology, Naval Pohang Hospital, Pohang, Korea Department of Pathology. Memorial Sloan Kettering Cancer Center Department of Radiology. Hospital for Special Surgery, New York, USA.

Purpose Of Review: Uterine sarcomas are rare and are often challenging to differentiate on imaging from benign mimics, such as leiomyoma. As functional MRI techniques have improved and new adjuncts, such as machine learning and texture analysis, are now being investigated, it is helpful to be aware of the current literature on imaging features that may sometimes allow for preoperative distinction.

Recent Findings: MRI, with both conventional and functional imaging, is the modality of choice for evaluating uterine mesenchymal tumors, especially in differentiating uterine leiomyosarcoma from leiomyoma through validated diagnostic algorithms. Read More

Cervical stromal involvement by endometrial 'hyperplasia': a previously unreported phenomenon with recommendations to report as stage II endometrial carcinoma.

Pathology 2021 Aug 18;53(5):568-573. Epub 2021 Jun 18.

Department of Pathology, Belfast Health and Social Care Trust, Belfast, United Kingdom. Electronic address:

A subtle 'burrowing' pattern of cervical stromal involvement by low-grade endometrioid adenocarcinoma of the uterine corpus is described in the literature. We report a small case series in which this pattern of cervical stromal involvement, warranting a diagnosis of endometrioid adenocarcinoma in the cervix, occurred in association with sometimes subtle endometrioid proliferations within the endometrium which fall short of the criteria for endometrioid adenocarcinoma and are in keeping with atypical hyperplasia or hyperplasia without atypia. In reporting this phenomenon, which has not been described previously, we highlight the importance of immunohistochemistry in the differential diagnosis, particularly in the exclusion of primary cervical glandular lesions, including those of mesonephric type.

Corded and Hyalinized and Spindled Endometrioid Endometrial Carcinoma: A Clinicopathologic and Molecular Analysis of 9 Tumors Based on the TCGA Classifier.

Am J Surg Pathol 2021 Aug;45(8):1038-1046

James Homer Wright Pathology Laboratories, Massachusetts General Hospital, Harvard Medical School, Boston, MA.

Corded and hyalinized and spindled carcinomas are rare variants of endometrioid carcinoma (EC) characterized by cords of low-grade epithelial cells (±spindle cells) within a hyalinized stroma or spindled epithelial cells, respectively, that merge with conventional low-grade EC. Due to their "biphasic" morphology, these tumors are often misdiagnosed as carcinosarcoma. The clinicopathologic features including mismatch repair protein (PMS2 and MSH6) and p53 immunohistochemical expression and POLE mutational status of 9 corded and hyalinized and spindled endometrial ECs were evaluated and classified into The Cancer Genome Atlas (TCGA) based molecular subgroups.

Atypical Endometrial Hyperplasia, Low-grade: "Much ADO About Nothing".

Am J Surg Pathol 2021 Jul;45(7):988-996

Department of Pathology, Hospital de la Santa Creu i Sant Pau, Institute of Biomedical Research (IIB Sant Pau), Autonomous University of Barcelona, Barcelona, Spain.

Atypical endometrial hyperplasia (AEH) is considered a precursor of endometrioid carcinoma. The 2020 World Health Organization (WHO) classification divides endometrial hyperplasia into 2 categories: hyperplasia without atypia and atypical hyperplasia/endometrioid intraepithelial neoplasia (EIN); however, this classification does not consider the degree of nuclear atypia. We graded nuclear atypia for estimating the risk of finding carcinoma at hysterectomy. Read More

Low-grade Endometrial Stromal Sarcoma With Sex Cord-like Differentiation and PHF1-JAZF1 Fusion With Deletions: A Diagnostic Pitfall of JAZF1 FISH.

Int J Gynecol Pathol 2021 Jun 2. Epub 2021 Jun 2.

Department of Pathology, Massachusetts General Hospital, Boston, Massachusetts (Z.O., V.N. D.D.-S., E.O.) Department of Pathology, Case Western Reserve University and University Hospitals Cleveland Medical Center, Cleveland, Ohio (S.A.).

The molecular knowledge on endometrial stromal neoplasms has been rapidly increasing and is considered complementary to morphologic and immunohistochemical findings for better categorization of these tumors. The most common molecular alteration observed in low-grade endometrial stromal sarcomas is the JAZF1-SUZ12 fusion, whereas, low-grade endometrial stromal sarcoma with sex cord-like differentiation have been shown more commonly to have fusions involving PHF1. Herein, we present a low-grade endometrial stromal sarcoma with sex cord-like differentiation with a fluorescence in situ hybridization showing the apparent loss of one copy of JAZF1 5' and 3' signals, rather than the expected "break-apart" pattern seen in the setting of a JAZF1 fusion.

Mesonephric-Like Carcinosarcoma of the Ovary Associated with Low-Grade Serous Carcinoma: A Case Report.

Diagnostics (Basel) 2021 May 3;11(5). Epub 2021 May 3.

Department of Emergency and Organ Transplantation, Section of Pathology, University of Bari "Aldo Moro", 70124 Bari, Italy.

Mesonephric adenocarcinomas are rare tumors of the female genital tract, thought to arise from embryonic mesonephric remnants, primarily in the cervix and vagina. Conversely, endometrial and ovarian mesonephric adenocarcinomas may have a different pathogenesis, probably originating from transdifferentiated Müllerian carcinomas, as demonstrated by the association of these neoplasms with endometriosis and ovarian serous tumors. For this reason, in the endometrium and in the ovary, they are defined as "mesonephric-like adenocarcinomas". Read More

Epidemiological link between obesity, type 2 diabetes mellitus and cancer.

World J Methodol 2021 May 20;11(3):23-45. Epub 2021 May 20.

Department of Endocrinology and Metabolism, Lancashire Teaching Hospitals NHS Trust, Preston PR2 9HT, United Kingdom.

There exists a complex interaction between obesity, type 2 diabetes mellitus (T2DM) and cancer, and an increase in the incidence of cancer is expected with the growing obesity-diabetes pandemic. The association of cancer with diabetes mellitus and obesity appears to be site-specific, the highest risk being for post-menopausal breast cancer, endometrial cancer, and colorectal cancer. Moreover, there is worsening of hyperglycaemia with the onset of cancer, evidencing a bi-directional link between cancer and diabetes mellitus and the need for monitoring for diabetes in cancer survivors.

Survey on Reporting of Endometrial Biopsies From Women on Progestogen Therapy for Endometrial Atypical Hyperplasia/Endometrioid Carcinoma.

Int J Gynecol Pathol 2021 May 3. Epub 2021 May 3.

Department of Cellular Pathology, Birmingham Women's Hospital, Birmingham (R.G.) Department of Pathology, Belfast Health and Social Care Trust, Belfast (W.G.M.), UK Department of Pathology and Laboratory Medicine, University of British Columbia, Vancouver, Canada (C.B.G.) Department of Pathology, Memorial Sloan-Kettering Cancer Center, New York, NY (R.A.S.).

Histologic assessment of response to progestogen therapy is a cornerstone of nonsurgical management of atypical hyperplasia/low-grade endometrioid carcinoma. Pathologists are required to assess whether there is ongoing preneoplastic or neoplastic change in the biopsies (often multiple) taken during therapy. There have been few studies documenting the specific histologic changes induced by therapeutic progestogens and currently there are no guidelines on terminology used in this scenario. Read More
