SPONTANEOUS SKIN TUMORS IN DOGS AND CATS, SQUAMOUS CARCINOMA
Abstract
Cutaneous cancers in pets have a constant development every year. In this investigation we purposed a study of canine skin tumors, detailing squamous carcinoma, and their correlations with breed, sex, age, and localization. In the same time was appreciated malignancy, based on microscopically images, especially nuclear aspect, cell homogeneity grade, the presence and grade of keratinisation, atypical mitosis, and cell polymorphism. In a period of 10 years had been diagnosed 597 animals with different tumor types, from these 202 being cutaneous neoformations; in carnivores were diagnosed 178 cases (88,3%) with cutaneous tumors. Squamous carcinoma had been diagnosed in 12 carnivores, respectivelly in dog 11 cases and 1 case in cat. The breeds diagnosed with squamous carcinomas were: Schnauzer (3 cases), stray dogs (2 cases), and one case for the folowing breeds: Rotweiler, Spaniel Cocker, German Brack, Doberman, and Fox Terrier. The localisation of squamous carcinoma was: legs – 4 cases, head region – 3 cases, and in cervical, scapula, dorsal and croup regions – 1 case for each region. Utilizing histological criteria for malignancy degree appreciation were established the following: squamous carcinoma with accentuated polymorph cells and increased number of mitosis (4 cases); squamous carcinomas with intense keratinisation (3 cases); squamous carcinomas with a reduced keratinisation (4 cases).
