Ultrasonography (IOTA‐ADNEX) vs magnetic resonance imaging (ADNEX MR) for diagnosing ovarian cancer in high‐risk patients: a prospective study

Ultrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objectives To systematically validate and compare ultrasonography, using the ultrasound‐based International Ovarian Tumor Analysis – Assessment of Different NEoplasias in the adneXa (IOTA‐ADNEX) model, with magnetic resonance imaging (MRI), using the MRI‐based ADNEX MR scoring system, as second‐line imaging modalities for estimating the risk ...

Transition Zone Prostate Cancer: Quantitative Synthetic MR Imaging and Diffusion‐Weighted Imaging in Tumour Detection

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Background Differentiating transition zone (TZ) prostate cancer (PCa) from benign prostatic hyperplasia (BPH) on multiparametric MRI is challenging. The comparative performance of synthetic MRI (Sy‐MRI) and apparent diffusion coefficient (ADC) for this task is unclear.

Pebbled mosaic‐like heterogeneous echogenicity in ovarian immature teratomas and correlation of ultrasound patterns with pathological grades

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
This study characterizes heterogeneous mottled grayscale ultrasound echoes of ovarian immature teratoma as the “pebbled mosaic sign,” noting solid lesions correlate with advanced pathological grades. Preoperative identification of immature tissue informs operative stratification. Abstract Introduction Ovarian immature teratomas (ITs) are rare malignant

Long‐term outcome of high‐grade encapsulated papillary carcinoma of the breast: implications for staging and management

Histopathology, EarlyView.
In the original study by Rakha et al., the authors proposed that high‐grade EPC should be considered within an invasive framework regardless of hormone receptor status. In the present study, we adopted a more selective definition of EPC‐A, restricted to tumours showing more adverse features, including high‐grade morphology together with triple‐negative

Merkel cell carcinoma: an updated guide for pathologists

Histopathology, EarlyView.
Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma for which the differential diagnosis can include other small cell malignancies (especially metastatic small cell carcinoma) or cutaneous carcinoma. Morphologic and immunophenotypic aberrancies in MCC can increase diagnostic challenge.

A bibliometric study on pancreatic cystic disease research

Journal of Pancreatology, 2019
. Pancreatic cystic disease is being increasingly identified in patients, and many relevant papers have been published in this field. A bibliometric analysis was previously performed to identify the most influential studies in many subject areas, and the

The Utility of Endoscopic Ultrasound Fine Needle Aspiration in Pancreatic Cystic Lesions Diagnosis

Diagnostics, 2020
The yield of biochemical analysis of pancreatic cysts fluid obtained via fine needle aspiration (FNA) is limited. We aimed to assess whether biochemical cyst analysis correlates with the endoscopic ultra-sonographic (EUS) diagnosis. A retrospective study

Distinct Rb expression pattern in HPV‐associated neuroendocrine carcinomas of the uterine cervix

Histopathology, EarlyView.
Most uterine cervical neuroendocrine carcinoma (UCNEC) cases are HPV‐associated and are characterized by partial loss of Rb, p16 overexpression, and cyclin D1 negativity. A minority of UCNECs exhibit a distinct pattern, characterized by HPV negativity, retained Rb expression, focal p16 expression and cyclin D1 positivity.
