Endometrial stromal sarcoma (ESS) is an aggressive uterine sarcoma. We report a case of a large endometrial stromal sarcoma in a 42 year nulliparous woman with chronic kidney disease presenting with acute urinary retention and irregular per vaginal bleeding. Ultrasound and Doppler imaging revealed a heterogeneous mass in the endometrial cavity with internal vascularity. Magnetic resonance imaging (MRI) revealed a large lobulated mass in the endometrial cavity extending into the vagina, causing local mass effect...

Uterine sarcoma is a very aggressive and highly lethal disease. Even after a comprehensive staging surgery or en block cytoreduction surgery followed by multimodality therapy (often chemotherapy and/or radiation therapy), many patients relapse or present with distant metastases, and finally die of diseases. The worst outcome of uterine sarcomas is partly because of their rarity, unknown etiology, and highly divergent genetic aberration. Uterine sarcomas are often classified into four distinct subtypes, including uterine leiomyosarcoma, low-grade uterine endometrial stromal sarcoma, high-grade uterine endometrial stromal sarcoma, and undifferentiated uterine sarcoma...

The 2014 World Health Organization (WHO) classification of uterine tumors revealed simplification of the classification by fusion of several entities and the introduction of novel entities. Among the multitude of alterations, the following are named: a simplified classification for precursor lesions of endometrial carcinoma now distinguishes between hyperplasia without atypia and atypical hyperplasia, the latter also known as endometrioid intraepithelial neoplasia (EIN). For endometrial carcinoma a differentiation is made between type 1 (endometrioid carcinoma with variants and mucinous carcinoma) and type 2 (serous and clear cell carcinoma)...

BACKGROUND: Previous studies on high grade sarcomas using mass spectrometry imaging showed proteasome activator complex subunit 1 (PSME1) to be associated with poor survival in soft tissue sarcoma patients. PSME1 is involved in immunoproteasome assembly for generating tumor antigens presented by MHC class I molecules. In this study, we aimed to validate PSME1 as a prognostic biomarker in an independent and larger series of soft tissue sarcomas by immunohistochemistry. METHODS: Tissue microarrays containing leiomyosarcomas (n = 34), myxofibrosarcomas (n = 14), undifferentiated pleomorphic sarcomas (n = 15), undifferentiated spindle cell sarcomas (n = 4), pleomorphic liposarcomas (n = 4), pleomorphic rhabdomyosarcomas (n = 2), and uterine leiomyomas (n = 7) were analyzed for protein expression of PSME1 using immunohistochemistry...

Dr. Louis "Pepper" Dehner is an internationally renowned surgical pathologist, especially in the subspecialty of pediatric pathology. Although his clinical and academic expertise are broad, with over 400 published articles, some of his most intriguing contributions have been in the area of pediatric renal and genitourinary pathology. This review focuses on the entities in these following organ systems where he has focused his efforts: malignant rhabdoid tumor, renal medullary carcinoma, Ewing sarcoma/peripheral neuroectodermal tumor, and the DICER1-related lesions cystic nephroma, embryonal rhabdomyosarcoma of the uterine cervix, and Sertoli-Leydig cell tumor...

Adenosarcomas are rare malignancies of the female genital tract, accounting for approximately 5 % of uterine sarcomas. Occasionally, adenosarcoma occurs in the ovaries or in extra-uterine tissue, which may be related to endometriosis. These tumors are characterized by benign epithelial elements and a malignant mesenchymal component. Pathologic diagnosis is dependent on the identification of the characteristic morphologic features. The most common immunohistochemical markers for adenosarcoma are CD10 and WT1, but these are not specific...

INTRODUCTION: Rhabdomyosarcoma has known as a highly malignant soft tissue sarcoma. It has been the most common soft tissue sarcoma in childhood, accounting for about 3 to 4 % of all cases of childhood cancer. Rhabdomyosarcoma was rare in adults, accounting for 3% of all soft-tissue sarcomas. embryonal rhabdomyosarcoma of female genital tract including uterine cervix in an adult was rare. CASE PRESENTATION: This study has reported a 33-year-old woman presented with abnormal vaginal discharge...

Well-defined poly(ethylene glycol)-b-allyl functional polylactide-b-polylactides (PEG-APLA-PLAs) are synthesized through sequential ring-opening polymerization. PEG-APLA-PLAs that have amphiphilic properties and reactive allyl side chains on their intermediate blocks are successfully transferred to core-shell interface cross-linked micelles (ICMs) by micellization and UV-initiated irradiation. ICMs have demonstrated enhanced colloidal stability in physiological-mimicking media. Hydrophobic molecules such as Nile Red or doxorubicin (Dox) are readily loaded into ICMs; the resulting drug-ICM formulations possess slow and sustained drug release profiles under physiological-mimicking conditions...

OBJECTIVE: Uterine sarcomas are rare, highly aggressive tumors with an unfavorable prognosis. The role of lymphadenectomy (LAD) remains controversial for this particular tumor type. To examine whether LAD can assist in prognosis or clinical benefits for uterine sarcoma patients, we performed a meta-analysis based on published studies. METHODS: We initially identified published studies by searching the PubMed database up to 30 November 2015. Study quality was evaluated systematically using the Newcastle-Ottawa Scale for assessing the quality of studies for inclusion in meta-analyses...

Uterine sarcomas are rare cancers characterized by clinical and histological polymorphism. They are malignant tumors of poor prognosis. Inaugural manifestation of acute abdomen with hemo-pneumoperitoneum and spontaneous uterine rupture remains exceptional. The authors report the case of a uterine leiomyosarcoma manifesting itself as an inaugural generalized acute peritonitis in a 43 year old woman. Uterine rupture due to malignant tumor was suspected during urgent preoperative imaging (ultrasound and CT scan) and confirmed histologically...

IMPORTANCE: Positron emission tomography/Computed tomography(PET/CT) is widely used for gynecologic cancers. OBJECTIVE: To determine when PET/CT should be used for gynecologic cancers. EVIDENCE ACQUISITION: PubMed was reviewed for articles on PET/CT of all gynecologic cancers. National Comprehensive Cancer Network, Society of Gynecologic Oncology, and American College of Radiology guidelines were reviewed. RESULTS: Whole-body PET/CT is useful for (1) initial staging of cervical and endometrial cancer, posttherapy assessment, radiation therapy planning, and posttreatment surveillance of cervical cancer, and (2) assessment of recurrence of cervical, endometrial, or ovarian cancer in the presence of symptoms...

Uterine endometrial stromal sarcomas including true low-grade endometrial stromal sarcoma (LG-ESS) and high-grade (HG-ESS) or undifferentiated endometrial sarcoma (UES) constitute a group of rare, aggressive malignancies. Most LG-ESSs express steroid receptors. Surgery is the principal primary therapy for endometrial stromal sarcomas and should be considered in all cases. These malignancies are relatively radio- and chemoresistant. Chemotherapy is used in recurrent and advanced HG-ESS and UES. Currently, the combination of gemcitabine and docetaxel is considered the most effective regimen, but at the expense of substantial toxicity...

BACKGROUND: While immunotherapy moved to the forefront of treatment of various cancers, it remains underexplored for uterine cancer. This might be due to the small patient population with advanced endometrial carcinoma and uterine sarcoma. Data about immunotherapeutic targets are scarce in endometrial carcinoma and lacking in uterine sarcoma. METHODS: Expression of five tumor-associated antigens (TAA) (BORIS, MUC1, hTERT, MAGE-A3 and Sp17) was validated in uterine tumor samples by immunohistochemistry (IHC) and/or quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR)...

BACKGROUND: Soft tissue sarcomas are heterogeneous and a major complication in their management is that the existing classification scheme is not definitive and is still evolving. Leiomyosarcomas, a major histologic category of soft tissue sarcomas, are malignant tumours displaying smooth muscle differentiation. Although defined as a single group, they exhibit a wide range of clinical behaviour. We aimed to carry out molecular classification to identify new molecular subgroups with clinical relevance...

Sarcomas are rare uterine tumors with leiomyosarcomas and endometrial stromal sarcomas constituting the predominant entities often making their first appearance in young and middle-aged women. By histology combined with immunostaining alone some of these tumors can offer diagnostic challenges e.g. for the differential diagnosis between leiomyosarcomas and smooth muscle tumors of uncertain malignant potential (STUMP). Areas covered: Recent advances in the genetic classification and subclassification, respectively, have shown that genetic markers can offer a valuable adjunct to conventional diagnostic tools...
