Histopathology

AIMS: To use the Delphi consensus methodology to establish standardized criteria for the histopathological diagnosis of adenomyosis. METHODS AND RESULTS: Between April and September 2024, a modified three-round Delphi consensus study was c…

AIMS: Clear cell carcinoma of ovary (CCC) is considered a high-grade malignancy by default and the role of histological grading for assessing clinical outcome is not established. We aimed to evaluate histopathological features associated wi…

AIMS: To report a series of benign ovarian seromucinous neoplasms, an uncommon and hitherto poorly described category of tumours included in the current 2014 World Health Organisation classification of tumours of the female reproductive org…

Endometriosis is an extremely common condition and, in most cases, establishing a histological diagnosis is straightforward, although a variety of benign alterations may result in problems with interpretation. In this review, I discuss sele…

AIMS: Inverted appendices are rare, but have the potential to cause diagnostic confusion among endoscopists and pathologists. The aim of this study was to describe the clinicopathological features of inverted appendices seen at our institut…

The authors state that there is no conflict of interest.

AIMS: MED12 exon 2 mutations have been identified in most uterine leiomyomas and mammary fibroepithelial tumours. MED12 has not been genotyped in most other gynaecological mesenchymal tumours. The purpose of this study was to determine the …

AIMS: To compare clinicopathological and immunohistochemical features of polypoid endometriosis (PE) and non-polypoid endometriosis (NPE). METHODS AND RESULTS: Fifteen cases of PE and 20 cases of NPE were assessed. All cases were stained im…

AIMS: The carcinogenesis of ovarian clear cell carcinoma (CCC) has been hypothesized to comprise two different pathways: an adenofibroma-carcinoma sequence and an endometriosis-carcinoma sequence. However, the difference in the genetic basi…

AIMS: The utility of routine histological examination of clinically primary spontaneous pneumothorax (SPTX) specimens has been questioned. In this retrospective study, we aimed to assess the clinical significance of unexpected SPTX histopat…

AIMS: Actinin-4, encoded by the ACTN4 gene located on chromosome 19q13.2, enhances cell motility by bundling the actin cytoskeleton. We assessed how ACTN4/actinin-4 alterations contribute to the tumorigenesis of ovarian clear-cell adenocarc…

AIMS: The secretoglobin mammaglobin 1 (MGB1) is strongly expressed in breast tumours, and is therefore used to detect breast cancer metastases, although it has also been detected in other tissues. The aim of this study was to examine MGB1 e…

AIMS: To identify the key cell-cycle dysregulations in the development of endometriosis-associated ovarian clear cell adenocarcinoma (CCA). METHODS AND RESULTS: Expression of p27(Kip1)-interacting cell-cycle regulators, such as p27(Kip1) it…

AIMS: Clinicopathological aspects of the endocervical-like mucinous borderline tumour of the ovary (EMBT), including higher frequencies of bilaterality, endometriosis and hormone receptor reactivity, and often admixtures of various Mülleria…

AIMS: Mucin 1 (MUC1) is an important tumour-associated antigen (TAA), both overexpressed and aberrantly glycosylated in adenocarcinomas. The aim of this study was to examine the MUC1-glycosylation status of primary ovarian adenocarcinomas a…

AIMS: To describe a series of endometrial stromal sarcomas with large numbers of endometrioid-type glands. METHODS AND RESULTS: The eight tumours occurred in patients aged 42-74 years. In three cases, the neoplasm arose in the uterine corpu…

Prolongation of ovarian epithelial cancer survival depends on early detection or improved responses to chemotherapy. Gains in either have been modest at best. Understanding the diverse pathogenesis of this disease is critical to early inter…

AIMS: Cellular retinol-binding protein-1 (CRBP-1) contributes to the maintenance of the differentiated state of the endometrium through retinol bioavailability regulation. The aim was to analyse CRBP-1 expression in endometrial stromal cell…

AIMS: In the female genital tract CD10 has been used to assist in the evaluation of mesenchymal tumours of the uterus and in determining whether endometrial stroma is present. CD10 positivity has also been shown in cervical mesonephric remn…
