Clinical and morphological features of mastocyte diagnosis in dogs

Mastocytoma is one of the most common skin tumours in dogs. It characterised by a specific course, unpredictable behaviour, and prognosis. This tumour dangerous because it mimics external signs other neoplasms, from less-threatening lipoma to cancer. The purpose study conduct pathomorphological verification classification neoplasia dogs diagnosed during clinical examination establish features morphological manifestation form mastocytoma them. material for studies was obtained excisional biopsy surgical interventions neoplasms. diagnosis established based on results animals neoplasms using cytological histological research methods. that share structure oncological diseases 30.12%. Among with were examined, 17.55% aged 3 14 years. highest incidence rates 7 12 Most often, following breeds: Shar Pei – 13.5%; Labrador 9.5%; Boxer 8.2%. Isolated cases formations observed such breeds as: German shepherd, Spaniel, Central Asian Shepherd, Pug. Depending gender: males accounted 52.2%, females 47.8%. In 50% examined animals, mastocytomas developed rapid dynamics, which indicates substantial aggressiveness growth. Clinically, dehydration gastrointestinal disorders detected dogs, development paraneoplastic syndrome. According sonography, are visualised as heterogeneous hypoechoic structures indistinct contours uneven edges. Based study, new information regarding mastocytes Thus, complement expand knowledge about pathogenesis frequency spread course this pathology separate geographical population Ukraine
