title: [An unusual occurrence of spinaliomas in schnauzers].
abstract: This paper describes 17 cases of digital spinocellular carcinomas of the limbs of the schnauzer dogs (14 in males and 3 in females) which were diagnosed from July 1987 to the end of 1988. During comparison of the prevalence of these neoplasmas over the period 1975 to 1984, when 11 cases of spinaliomas were diagnosed in dogs, there is an uncommonly high and interesting incidence of these tumors in schnauzers. Spinaliomas were not diagnosed in other breeds and in other locations. We know of no other similar observation. The tumour had the appearance of a poorly mending wound or panaritium and they locally destroyed the digits of the affected individuals. Recurrence was observed once, metastases in lymphatic nodes or other tissues were not observed up to the present time. Histologically the tumors had the appearance of well differentiated spinocellular carcinomas with a fibro-producing and intensive inflammatory reaction. The sarcomatous appearance of the tumor parenchyma was sporadically observed. Lesions were indications for the amputation of the affected digits. As possible etiological factors the authors consider, besides traumatic influences of the overgrown claws, even hormonal and infectious influences.
