Article Abstract
Objective: Early gastric cancer (EGC) is defined as cancer invasion confined to the mucosa or submucosa, irrespective of lymph node metastasis. Recently endoscopic submucosal dissection (ESD) has been widely accepted for the treatment for dysplasia and EGC without lymph node metastases. While the method has been advanced in Far East countries, ESD is still being developed in Europe and has not gained enough popularity although it has been recommended as the treatment of choice for superficial gastric neoplastic lesions by European Society of Gastrointestinal Endoscopy (ESGE) in 2015.
Methods: The aim of the study was to perform a retrospective analysis of clinical and histomorphologic features of 58 cases of EGCs removed by ESD in a university hospital in Western Pomerania in Poland and to evaluate factors related to the efficiency of ESD resection.
Results: With univariate analysis, indications for ESD with the highest R0 rate were found in EGCs limited to mucosa (T1a, small mucosal, M), without muscularis mucosa invasion, localised in the middle/lower part of stomach and intestinal type in histological examination. The R0 complete resection rate was significantly (p < 0.0001) lower for T1b than that for T1a tumours (21.4% vs. 100%). Tumours with submucosal involvement were associated with lower efficiency of ESD procedure.
Conclusions: Our data showed that in EGCs with favourable histomorphologic characteristics, ESD seemed to be a totally efficient and safe method of treatment in a European small-volume centre. R0 resection rate reached 81.1% of cases and median time of the ESD procedure was 61.5 min.

Purpose: We reviewed recent advancements in the characterization of intraductal oncocytic papillary neoplasm (IOPN) of the pancreas, with a specific focus on developments in immunohistochemical markers, molecular pathology, and pathogenic mechanisms over the past ten years (2015-2024). Through comprehensive analysis of current literature, we aimed to elucidate the evolving understanding of IOPN's biological behavior and diagnostic features, while identifying potential areas for future research in this distinctive pancreatic neoplasm.
Methods: English-language articles on IOPN were searched from Pubmed from the first report of IOPN of the pancreas in 2015 to 2024.

This study aimed to investigate the clinicopathological features and diagnostic strategies of CD30-negative classic Hodgkin lymphoma (cHL) based on core needle biopsy specimens. Six cases diagnosed at Yantai Yuhuangding Hospital and Beijing Gaobo Boren Hospital were retrospectively analyzed. The diagnosis was established through integrated evaluation of histomorphology and immunohistochemical (IHC) profiling.

The histomorphological features of the internal system in insects are considered important for understanding their biology. Julodis ehrenbergii Laporte, commonly known as the "jewel beetle or metallic wood-boring beetle," belongs to the family Buprestidae, and it is generally known that it feeds on pistachio, oak, blackberry apricot, and Alhagi mannifera Jaub. & Spach plants.

Osteoarthritis (OA) is a chronic disease characterized by pain, swelling, and joint stiffness, affecting all components of the joint and periarticular tissues. This study aimed to evaluate the histomorphological features of synovial tissue obtained during total knee arthroplasty in patients with grade 4 primary OA and to explore the relationship between synovitis scores and associated pathological changes. This retrospective, single-center cohort study included 115 patients who underwent total knee arthroplasty for grade 4 primary OA between 2020 and 2023.

Background: Accurate subtyping and risk stratification are imperative for prognostication and clinical decision-making in small cell lung cancer (SCLC). However, traditional molecular subtyping is resource-intensive and challenging to translate into clinical practice.
Methods: A total of 517 SCLC patients and their corresponding hematoxylin and eosin (H&E)-stained whole slide images (WSIs) from three independent medical institutions were analyzed.
