Abstract
The material for the study was a group of 34 dogs of different age groups, operating and biopsy material, which was sent to a laboratory from the veterinary clinics of the city of Dnipro. Basal cell carcinoma in dogs takes first place in distribution, it accounts for about 20% of all skin tumors. The basal cell carcinoma of the skin affects more often dogs older than five years, 71% of the diseased animals are 7-9-year-old, in 65% of cases, males are ill. The disease appeared as exophytic growth on the surface of the skin of 80% of dogs, the dominant site of the basaliosis was the head (47%) and the neck (32%) of dogs, rarely limbs (11%), spin (6%) and other body parts (4%). Among the clinical forms, 4 forms were found: superficial (35%), more seldom nodule (26%), ulcer (23%) and scar tissue (16%). During the histological study, it was found that two forms of basal cell crayfish are the most common: solid (52%) and ribbons (36%) forms. All other forms account for only 12%. Microscopically, on the histological section, the tumor is constructed from small rounded and spindle-shaped cells with a rim of basophilic cytoplasm, which resemble basal cells of the epidermis, but without intercellular bridges. The cells are located predominantly with struts. In the course of cytological examination of basal cell skin cancer, 4 forms were identified: surface multicentric (45%), scleroderma (27%), fibroepithelial (16%), pigmentary (12%). During the cytological study of basal cell carcinoma of the skin, it has been established that in the cytology of the cells of the flat epithelium, basaliosis has hyperchromic cells of a cylindrical shape. Cell nuclei are round, large. Basophil cytoplasm, small in size, has fuzzy contours, no intercellular bridges.
