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.

Although a diagnosis of anaplastic thyroid carcinoma (ATC) can be rendered on fine needle aspiration (FNA), a core needle biopsy is often performed to provide sufficient material for immunohistochemical and molecular analysis. Rendering an ATC diagnosis on core biopsy can be challenging due to limited material. It is crucial that other diagnostic entities in the differential, such as poorly differentiated thyroid carcinoma, medullary thyroid carcinoma, lymphoma, metastases, and NUT carcinoma (among others), are considered and that immunohistochemistry (IHC) is employed judiciously to support the diagnosis.

Purpose Of Review: Diagnosing sarcoidosis remains challenging. Histology findings and a variable clinical presentation can mimic other infectious, malignant, and autoimmune diseases. This review synthesizes current evidence on histopathology, sampling techniques, imaging modalities, and biomarkers and explores how emerging 'omics' and artificial intelligence tools may sharpen diagnostic accuracy.

Material And Methods: The material is represented by biopsy specimens of m. tibialis anterior, m.

Systemic mastocytosis (SM) is a rare clonal mast cell disease characterized by heterogeneous clinical presentations and molecular features that vary across different regions; however, data from Central-Eastern Europe remain limited. This study aimed to describe the demographic, clinical, laboratory, and molecular characteristics of Romanian adults diagnosed with SM and followed at the national reference center for mast cell disorders in Bucharest, while also exploring real-world management patterns and outcomes. We conducted a retrospective observational study including 162 adult patients evaluated between January 2006 and March 2025 who met the 2022 World Health Organization criteria for SM.
