BACKGROUND Catamenial pneumothorax (CP) is a spontaneous pneumothorax commonly associated with menstrual periods. Endometrial tissues most commonly involve the pelvic region. However, after the pelvis, the lungs are most frequently involved. Thoracic endometriosis should always be suspected in young women presenting with CP. CASE REPORT A 30-year-old woman with history of endometriosis presented with chief complaint of umbilical pain. A computerized tomography (CT) scan of the abdomen and pelvis was performed, which showed an incidental finding of a large right-sided pneumothorax...

There are no widely accepted pathologic criteria for reporting endometrial samples with limited tissue and no consensus on the clinical follow-up of patients with these samples. Our study compares clinicopathologic outcomes and determines reporting consistency for these samples. This was done in 3 parts: (1) retrospective chart review of all patients with reported insufficient or scant endometrial samples from 2010 to 2013 at our center to determine repeat sampling and final pathologic diagnosis; (2) survey of gynecologists about their practice for managing patients with these samples; (3) blind review of 99 cases of previously reported scant or insufficient samples in which 4 reviewers separately reassigned cases as scant, insufficient, or diagnostic...

Although the spread of extragenital tumors to individual female genital tract organs, particularly the ovary, has been much studied, histologic data with regard to secondary tumors involving the whole gynecologic tract are largely lacking. Thus, the aim of the study was to investigate the pathologic and clinical features of these tumors in order to better understand their features. This is a retrospective study of 196 secondary lesions involving the gynecologic tract. The parameters studied were the primary site, its histologic type and grade, the presence of mucous production, the type of secondary involvement, defined as distant metastasis, direct extension or locoregional recurrence, and the time to metastasis...

Three types of endometriosis are described: superficial peritoneal endometriosis (SPE), ovarian endometrioma (OMA), and deep infiltrating endometriosis (DIE). The expression of somatostatin receptors (SSTR1, 2, and 5) in human endometrial tissue and its ectopic form has been previously studied and may be different in each type of endometriosis. The aim of this study was to assess the immunohistochemical expression of SSTR1, 2, and 5 in tissue samples of SPE, OMA, and DIE. We performed a retrospective analysis in the pathology department database...

Endometrial biopsy or curetting is indicated for postmenopausal women with abnormal uterine bleeding and/or thickened endometrium. Often, endometrial biopsy or curetting yields limited benign surface endometrium, which may indicate insufficient sampling. This study addresses the clinical outcome and subsequent pathologic diagnoses in postmenopausal women who received this initial diagnosis. Among a total of 370 endometrial biopsy or curetting between 2012 and 2015, 192 (52%) were diagnosed as limited benign surface endometrial epithelium...

Vasculopathy is one of the primary pathological changes in chronic rejection of vascularized allograft transplantation. Endometrial regenerative cells (ERCs) are mesenchymal-like stromal cells with immunosuppressive effect. B7-H1 is a negative costimulator that mediates active immune suppression. The aim of this study was to investigate the requirement of B7-H1 in the immunoregulation of ERCs in preventing transplant vasculopathy of aorta allografts. The results showed that B7-H1 expression on ERCs was upregulated by IFN- γ in a dose-dependent manner and it was required for ERCs to inhibit the proliferation of peripheral blood mononuclear cells (PBMCs) in vitro ...

Human Leukocyte Antigen-G (HLA-G) is known as an immune suppressive molecule; it interacts with several immune cells and inhibits their functions. HLA-G molecule is highly represented in pathological conditions including malignant transformation. To the best of our knowledge this is the first study that focuses on the expression of soluble HLA-G (sHLA-G) in endometrial cancer (EC). We aimed at exploring sHLA-G plasma levels and its prognostic value in EC. We examined total sHLA-G expression as well as the sHLA-G1 and HLA-G5 isoforms expression in plasma samples from 40 patients with EC and 45 healthy controls by a specific sandwich ELISA...

The tumor suppressor PTEN controls multiple cellular functions, including cell cycle, apoptosis, senescence, transcription, and mRNA translation of numerous genes. In tumor cells, PTEN is frequently inactivated by genetic mutations and epimutations. The aim of this study was to investigate the methylation patterns of the PTEN gene and its pseudogene PTENP1 as potential genetic markers of endometrial hyperplasia (EH) and endometrial carcinoma (EC). Methylation of the 5'-terminal regions of the PTEN and PTENP1 sequences was studied using methyl-sensitive PCR of genomic DNA isolated from 57 cancer, 43 endometrial hyperplasia, and normal tissue samples of 24 females aged 17-34 years and 19 females aged 45-65 years, as well as 20 peripheral venous blood samples of EC patients...

Stem/progenitor cells for cell therapy and regenerative medicine should ideally be available in large numbers, after having been isolated using minimally invasive or non-invasive methodologies. Also, they should exhibit wide differentiation potential into multiple lineages, as well as capability to be used successfully in autologous or allogeneic transplantation, and all this in accordance with the applicable guidelines of good manufacturing practice. Thus, the identification and characterization of alternative sources of mesenchymal stem cells (MSCs) is of great importance...

Small cell carcinoma of the ovary, hypercalcemic type is a rare, aggressive malignancy which usually occurs in young women and is characterized by mutations in SMARCA4, with few other alterations. We recently encountered uterine tumors with morphologic, immunohistochemical, and genetic similarities to small cell carcinoma of the ovary, hypercalcemic type. Herein we report the clinicopathologic and molecular features (using a targeted massively parallel sequencing [MPS] assay) of these tumors. The cases were diagnosed on cervical and endometrial biopsies (n = 2, 34, and 29 years) or hysterectomy and bilateral salpingo-oophorectomy (n = 3, 25, 33, and 58 years)...

BACKGROUND There are few reports of breast cancer cases with uterine metastases; among them, myometrium is more frequently involved than endometrium. The majority of breast cancer metastases to endometrium are lobular type, and there have been only 5 reported cases of ductal type since 1984. Here, we describe a new case of invasive ductal carcinoma with metastases to endometrium and isolated presentation of abnormal uterine bleeding, in addition to reviewing the existing literature on other similar cases. CASE REPORT The patient was a 51-year-old Persian woman with no remarkable past medical or family history of cancer, who presented with a 6-month complaint of menorrhagia to our gynecology clinic...
