Core-Needle Biopsy Efficacy in Histopathology Diagnosis of Canine Multicentric Lymphoma.

Core-needle biopsy (CNB) is now widely used to diagnose and classify human lymphoma. Few studies, however, have reported the use of CNB in veterinary medicine for dogs with suspected lymphoma. The present study evaluated the efficacy of CNB sample collection to diagnose canine multicentric lymphoma morphology.

PGAM1 and TP53 mRNA levels in canine mammary carcinomas - Short communication.

TP53 and PGAM1 genes play a key role in glycolysis which is an essential metabolic pathway of cancer cells for obtaining energy. The purpose of this work was to evaluate PGAM1 and TP53 mRNA expressions in canine mammary carcinomas (CMC) and to correlate them with animal data and tumour histological features. None of the nine samples analysed revealed PGAM1 DNA sequence variations.

Histopathological findings in the early diagnosis of granulosa cell tumour in bitches.

Granulosa cell tumour (GCT) is a majorly observed ovarian tumour in female dogs. It is essential to diagnose GCT in its initial phase before any symptoms occur, as histological and physiological differences may be observed based on the evolution of this neoplasia. This study aimed to analyse the anatomic histopathology of GCT in its initial stage, with findings of ovaries not yet with the suspicion of neoplasms in the Canis familiaris.
