Nipple‐Originating Solid Papillary Carcinoma In Situ: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Solid papillary carcinoma of the breast is a rare histopathological subtype of papillary neoplasms, and its in situ variant localized to the nipple is particularly uncommon. Current oncology literature provides limited evidence on standardized diagnostic criteria, biological behavior, and optimal treatment strategies for this entity.

Cytologic and Histologic Findings of Extrapleural Solitary Fibrous Tumor: Report of Two Cases

Diagnostic Cytopathology, Volume 54, Issue 2, Page E46-E53, February 2026.
ABSTRACT Solitary fibrous tumors (SFT) are a rare neoplasm of mesenchymal origin. SFT was previously described primarily in the pleura and meninges; however, extrapleural and extra‐meningeal SFT have been reported in almost every anatomic site and account for up to 40% of cases.

Practice of Cytopathology in Korea: A 40‐Year Evolution Through Standardization, Digital Transformation, and Global Partnership

Diagnostic Cytopathology, Volume 54, Issue 2, Page 146-159, February 2026.
ABSTRACT Over four decades, Korea has advanced from a limited cytology service to a global model of digital and AI‐integrated cytopathology. Since the founding of the Korean Society for Cytopathology (KSC) in 1986, a nationwide framework has been established—encompassing standardized practices, systematic education for specialists and cytotechnologists,

Multiparametric Ultrasound for Preoperative Assessment of Parotid Tumors: A Novel Diagnostic Pathway

Head &Neck, Volume 48, Issue 2, Page 392-406, February 2026.
ABSTRACT Background Accurate preoperative differentiation of parotid gland tumors (PGTs) is essential for facial nerve preservation. This study evaluates a novel, real‐time multiparametric ultrasound (mpUS) approach combining B‐mode, shear wave elastography (SWE), and contrast‐enhanced ultrasound (CEUS), based on qualitative image interpretation ...

Diagnostic Accuracy of HPV Circulating Tumor DNA Following Non‐Diagnostic FNA of a Cystic Lateral Neck Mass

Head &Neck, Volume 48, Issue 2, Page 543-548, February 2026.
ABSTRACT Background Cystic lateral neck masses in adults commonly represent nodal metastases from HPV‐associated oropharyngeal squamous cell carcinoma (OPSCC) or benign lesions. Because cystic lesions are relatively acellular, fine‐needle aspiration (FNA) is often non‐diagnostic.

New cell lines expanding the diversity of Ewing sarcoma models

International Journal of Cancer, Volume 158, Issue 3, Page 642-655, 1 February 2026.
What's new? A chromosomal translocation between the EWSR1 and ETS genes is the key oncogenic driver in Ewing sarcoma. EWSR1::FLI1, the most frequent fusion, is subdivided into different fusion types with unclear prognostic relevance. Here, the authors describe the establishment and characterization of four new, intrinsically immortal, patient‐derived ...
