Background Osteosarcoma (OSA) should be differentiated from other less frequent primary bone neoplasms, metastatic disease, and tumor‐like lesions, as treatment prognosis can vary accordingly. Hence, a preoperative histologic diagnosis is generally preferred. This requires collection of multiple biopsies under general anesthesia, with possible complications, including pathological fractures. Fine‐needle aspiration cytology would allow an earlier significant reduction discomfort morbidity....

Rare Earth Elements (REEs) are strategical elements playing a crucial role in the industry, especially producing high-tech materials. Therefore, REEs new contaminants of emerging concerns. However, due to lack exposure data on REE occurrence environmental matrices, European countries, it is still tricky establish background levels assess ecotoxicological risk related exposure. The present study aimed evaluate liver concentrations domestic dogs (Canis lupus familiaris) and Apennine wolves...

Mammary carcinomas are the most common neoplasms observed in women and female dogs. Canine mammary tumors show epidemiological, clinical, genetic, prognostic characteristics comparable to human breast cancers. The recent introduction of next generation sequencing (NGS) technologies has greatly improved research diagnostics for humans, while these new tools still need be implemented animal models. In this study we developed validated an AmpliSeq Panel assay identification BRCA variants...

Pets have a crucial role in cancer research. Specifically, dogs and cats share the same environment as their owners thus may serve sentinels of naturally occurring tumors that are linked to exposure environmental hazards. Quantitative comparison tumor types reveal unusual frequencies, providing directions for research generation hypotheses causation specific area identification risk factors. The aim this study was describe data collected by pathology-based animal registry, managed Istituto...

Mast cells (MCs) are involved in angiogenesis, tissue remodeling and immunomodulation several human animal tumors, although their exact role is still controversial. Since no information available canine prostate carcinoma (PC) normal tissues, the aims of this study were to evaluate possible correlations between MC distribution, molecular expression microvessel density (MVD) prostatic proliferative disorders prostate. All samples (6 normal, 15 benign hyperplasia-BPH, 8 PC) stained with...

A large, ill-defined, firm, multinodular mass involving the pancreas was confirmed on postmortem examination of a 5-y-old, male Rottweiler that died following acute respiratory distress syndrome, after period anorexia and lethargy. Histologically, consisted plump spindle cells admixed with variable number macrophages, lymphocytes, plasma cells, neutrophils. Foci coagulative necrosis hemorrhage were also observed. Spindle strongly reacted to antibodies against vimentin, α–smooth muscle actin,...
