We present a new endometrial stromal sarcoma (ESS)-associated genomic rearrangement involving chromosome arms 5p and 6p and leading to the formation of a BRD8-PHF1 fusion gene. The PHF1 (PHD finger protein 1) gene, from 6p21, is known to be rearranged in ESS in a promiscuous way inasmuch as it has been shown to recombine with JAZF1, EPC1, MEAF6, and now also with BRD8, in tumors of this type. In all rearrangements of PHF1, including the present one, a recurrent theme is that the entire coding part of PHF1 constitutes the 3' end of the fusion...

OBJECTIVE: Professional societies have recently urged gynaecologists to counsel patients about the risks of encountering uterine sarcoma at fibroid surgery especially when morcellation is used. Our objective was to learn the preoperative and postoperative characteristics of patients with uterine sarcoma to better counsel patients undergoing surgery for presumably benign fibroids. METHODS: This is a multicentre, retrospective cohort study. Three academic tertiary cancer centres in Southern Ontario over a 13-year period (2001-2014)...

Distinguishing between uterine neoplasms of smooth muscle and endometrial stromal origin is a frequent diagnostic challenge. We investigated the staining pattern of interferon-induced transmembrane protein-1 (IFITM1), a novel endometrial stromal marker, in endometrial and smooth muscle uterine neoplasms and compared it with CD10 in its ability to differentiate between these two groups. Immunohistochemistry for IFITM1 and CD10 was performed in 20 cases of smooth muscle neoplasms (10 cases leiomyoma, 10 cases leiomyosarcoma), 14 cases of endometrial stromal sarcoma (ESS) (12 cases of low grade and 2 cases of high grade) and 12 cases of carcinosarcoma...

The objective of this study was to validate the diagnostic and clinical role of four protein products of genes previously found to be differentially expressed in uterine low-grade endometrial stromal sarcoma (LG-ESS) compared to uterine leiomyosarcoma (LMS). Protein expression by immunohistochemistry of transgelin (TGLN), neuron navigator-2 (NAV2), fatty acid binding protein-3 (FABP3), and cyclin D2 (CCND2) was analyzed in 305 uterine sarcomas (231 LMS, 74 LG-ESS). Expression was analyzed for association with clinicopathologic parameters and survival...

Recognition of high-grade endometrial stromal sarcoma is important because of its aggressive clinical behavior. Morphologic features of YWHAE-NUTM2 high-grade endometrial stromal sarcoma may overlap with other uterine sarcoma types. BCOR immunoexpression was studied in these tumors and their morphologic mimics to assess its diagnostic utility. BCOR immunohistochemical staining was performed on archival tissue from 28 high-grade endometrial stromal sarcomas with classic morphology (20 YWHAE-NUTM2, 5 ZC3H7B-BCOR, 3 BCOR-ZC3H7B), 3 high-grade endometrial stromal sarcomas with unusual morphology and unknown gene rearrangement status, 66 low-grade endometrial stromal sarcomas, 21 endometrial stromal nodules, 38 uterine leiomyosarcomas, and 19 uterine leiomyomas...

Large-cell neuroendocrine carcinoma (LCNEC) is a high-grade neuroendocrine tumor. LCNECs arising from the genital organs are highly malignant and rare, with <20 cases of LCNEC developing from the uterine endometrium reported to date. We herein present the case of a patient with LCNEC of the endometrium. The patient was a 52-year-old woman, who exhibited lower abdominal pain and rapid uterine enlargement during outpatient treatment for uterine myoma. The endometrial biopsy suggested a diagnosis of poorly differentiated carcinoma or carcinosarcoma...

Endometrial stromal tumors include translocation-associated low- and high-grade endometrial stromal sarcomas (ESS) and highly malignant undifferentiated uterine sarcomas (UUS). UUS is considered a poorly defined group of aggressive tumors and is often seen as a diagnosis of exclusion after ESS and leiomyosarcoma (LMS) have been ruled out. We performed a comprehensive analysis of gene expression, copy number variation, point mutations, and immune cell infiltrates in the largest series to date of all major types of uterine sarcomas to shed light on the biology of UUS and to identify potential novel therapeutic targets...

BACKGROUND: Endometrial stromal sarcomas arising in extrauterine and extraovarian sites, in the absence of a primary uterine lesion are quite rare, especially in the absence of endometriosis. They usually present as an abdominal or pelvic mass lesion. CASE PRESENTATION: In 2007, a 45-year-old woman underwent total hysterectomy for in situ squamous cell carcinoma of the cervix. In 2014, an upper left pulmonary lobectomy was performed for a mass, which was provisionally diagnosed as primary carcinosarcoma of the lung...

Collision tumours are defined by co-existence of two tumours in the same or adjacent organs which are topographically and histologically distinct with minimal or no histological admixture. Collision tumours have been described in many organs notably thyroid, brain, adrenal gland, stomach and rarely uterus. Most of the collision tumours reported in uterus have two components; an adenocarcinoma and a sarcoma. We report a case of a 60-year-old lady who presented with complaints of post-menopausal bleeding. A cervical biopsy was performed which showed a non-keratinizing squamous cell carcinoma of cervix...

There have been several updates recently on the classification of uterine tumors. Endometrial carcinomas have traditionally been divided into 2 types, but some are difficult to classify and do not fit readily into either of the currently recognized categories. The Cancer Genome Atlas Research Network has recently defined 4 new categories of endometrial cancer on the basis of mutational spectra, copy number alteration, and microsatellite instability, which might provide independent prognostic information beyond established risk factors...

REVIEW
Ben Davidson, Francesca Micci
Uterine sarcomas are rare cancers, of which the most common entities are leiomyosarcoma and endometrial stromal sarcoma. These two tumors may have overlapping clinical presentation, morphology and immunohistochemical profile, but are increasingly recognized to be two molecularly distinct entities. Endometrial stromal sarcomas are further currently divided into a low-grade and high-grade group based on molecular characteristics. Area covered: This review discusses recent data which shed light on the molecular profile of these two cancers and may aid in understanding their evolution and progression, in the aim of improving their diagnosis and management...
