Morphological features of tumors of the eye in dogs ; Морфологічні особливості новоутворень ока у собак

Tumors of the eyes in pets are relatively rare. Tumors can adversely affect the functions of the eye, lead to damage to its structures, discoloration, discomfort or changes in the shape of the eyeball. The study of the morphological features of neoplasms of the eye has not only scientific or general biological interest, but also has a purely practical significance.The purpose of our work was to study the frequency of diagnosis, morphological, clinical and macroscopic features of various histological types of eye neoplasms. It was analyzed 178 cases of tumors of different localization in dogs that were admitted to the Department of Pathological Anatomy of the NUP of Ukraine for histological examination from various clinics of veterinary medicine in Kyiv. Neoplasms of the eye were about 3%. The ratio between malignant and benign neoplasms was 1:1. The average age of the sick dogs was 7 years. Most often the eyelids and other parts of the eye's auxiliary apparatus were affected. In only one case, an intraocular tumor was noted. Such statistics are not accurate, as most owners refuse surgical removal of the eyeball. The prevailing clinical form of neoplasm was nodular. Macroscopically, most tumors had a regular oval shape. In one case, an ulcer was found on the surface of the tumor. The melanoma of the uveal tract, the squamous cell carcinoma of the eyelid, the eccrine acrospiroma of the sweat glands of the eyelids, the adenocarcinoma of the sebaceous glands of the eyelids, the hemangioma of the orbit and neurofibroma were diagnosed. Histologically, the neoplasms of the eye did not differ from other similar localizations.The obtained data will supplement the knowledge of researchers of other countries about the histological structure of tumors that are recorded in the eye area, as well as the role of the geographical factor, environmental conditions in the development of oncological pathology. ; Пухлини ока у домашніх тварин реєструються відносно рідко.
