Novel Combined Approach for Vision‐Preserving Iridociliary Tumour Excision in a Small‐Breed Dog: Contralateral Iris Excision With En‐Bloc Scleral Resection

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
• A 2.8 mm corneal paracentesis positioned opposite to the tumour location enabled fine iris scissors insertion for precise excision of tumour‐bearing iris tissue under miotic guidance with pilocarpine 2%. • A fornix‐based conjunctival peritomy 5 mm from the limbus and stepped scleral flap approach allowed circumferential deep scleral incision with 2–3

Testicular mass frozen section examination: Pathological insights and diagnostic accuracy

Histopathology, Volume 88, Issue 4, Page 843-853, March 2026.
Frozen section examination on testicular excisional biopsy is accurate and can help avoid unnecessary radical orchidectomy. A very high concordance rate between frozen section diagnosis and permanent diagnosis was obtained with no false negatives.

RB1 inactivation in cutaneous carcinomas

Histopathology, Volume 88, Issue 4, Page 769-789, March 2026.
Among skin carcinomas, recurrent RB1 inactivation is observed in Merkel cell carcinoma, in a subset of squamous cell carcinoma with bowenoid morphology, in sebaceous carcinoma and in the recently described Wnt/beta‐catenin rosette‐forming carcinoma.

The spectrum of breast in situ papillary carcinomas with invasion and invasive breast carcinomas with papillary features: an overview of histological subtypes and diagnostic challenges

Histopathology, Volume 88, Issue 4, Page 747-768, March 2026.
Invasive breast carcinomas with papillary features (IBCP) comprise diverse subtypes with variable architecture, histopathology, and clinical behaviour. This review outlines evolving classification, diagnostic criteria, and treatment implications, highlighting challenges in distinguishing in situ from invasive lesions. Standardised diagnostic approaches

Prognostic Value of a Histopathological Scoring System and the Ki67 Proliferation Index in Dogs With Phaeochromocytoma

Veterinary and Comparative Oncology, Volume 24, Issue 1, Page 11-20, March 2026.
ABSTRACT Canine phaeochromocytomas (PCCs) are neuroendocrine tumours with malignant potential. Metastatic disease remains the sole definitive evidence of malignancy. Histopathological criteria to predict long‐term survival have not been established in dogs.

Tissue Proteomics of Feline Mammary Carcinoma: Differences in Protein Profiles Among Histological Grades Using Liquid Chromatography–Tandem Mass Spectrometry

Veterinary and Comparative Oncology, Volume 24, Issue 1, Page 128-139, March 2026.
ABSTRACT Mammary carcinomas are aggressive neoplasms and a significant cause of mortality in female cats. Despite surgical removal, feline mammary carcinoma (FMC) often recurs or metastasizes. Specific tumour biomarkers are necessary for early detection, prognosis and therapy selection.

Serum Symmetric Dimethylarginine as a Predictor of Toxicity of Carboplatin in Dogs

Veterinary and Comparative Oncology, Volume 24, Issue 1, Page 140-149, March 2026.
ABSTRACT Glomerular filtration rate (GFR) predicts carboplatin clearance and myelotoxicity in humans and cats. This relationship is unknown in dogs. In canines, elevated serum symmetric dimethylarginine (SDMA) correlates with reduced GFR. This study prospectively evaluated whether dogs with elevated SDMA (> 14 μg/dL) are at increased risk of ...
