Unveiling the swirl sign: A radiologic-pathologic correlation in deep angiomyxoma.

Deep angiomyxoma (DA) is a rare, slow-growing soft tissue tumor typically affecting women of reproductive age. Despite its benign histology, it poses significant clinical challenges due to local invasiveness and high recurrence. Accurate diagnosis through radiologic imaging, particularly MRI, is essential for guiding treatment.

Intraoperative peritoneal cytology for cervical gastric-type adenocarcinoma: Cytopathology and clinical impact.

Background: The objective of this study was to elucidate the frequency and cytologic features of positive peritoneal washing cytology (PWC) in cervical gastric-type adenocarcinoma (GAS) and to clarify the clinical significance of positive PWC.

Methods: The authors analyzed cases from their institution between 1991 and 2023 in which patients underwent surgery and PWC. The study included 62 patients who had cervical GAS (1991-2023; including seven patients with adenocarcinoma in situ and 26, 15, nine, and five patients with International Federation of Gynecology and Obstetrics 2018 stage I, II, III, and IV disease, respectively) and 100 patients who had usual-type endocervical adenocarcinoma (2007-2023; including 65, 15, and 20 patients with stage I, II, and III disease, respectively).

Mismatch Repair Protein Expression in Endometrial Cancer: Assessing Concordance and Unveiling Pitfalls in Two Different Immunohistochemistry Assays.

This study aimed to compare the concordance and interchangeability of the Dako/Agilent and Ventana/Roche mismatch repair (MMR) immunohistochemistry (IHC) assays commonly used in pathology. It also aimed to provide diagnostic insights by examining the frequency and characteristics of the dot-like artifact observed in MLH1 M1 clone staining in endometrial cancer. Fifty endometrial cancer cases with MMR deficiency, excised between 2011 and 2018, were included in the study.
