Roe deer (Capreolus capreolus) warts - fibromas, papillomas or fibropapillomas

Roe deer fibropapillomatosis is mainly benign neoplastic disease caused by papillomaviruses. Previously, based on the gross appearance of the lesions such skin tumours were usually classified by practitioners as fibromas and papillomas. On the other hand, a part of the literature describes these lesions as fibropapillomas.The aim of the study was to determine histologic characteristics of the lesions in roe deer in order to improve the knowledge of the appearance of papillomavirus induced neoplastic lesions in roe deer in Croatia. As part of the surveillance of wildlife diseases, three roe deer with few clearly visible skin lesions were presented to the Veterinary Faculty. Gross examination was taken on a field while samples of the lesions were alcohol fixed and submitted for histopathological analysis (routine HE staining). Grossly, lesions were ranging in size from 1.5 to 19 cm. Some of these lesions were covered with intact skin, while in others surface was hyperkeratotic and hyperpigmented with several ulcerations. Histopatological analysis revealed elements characteristic for both fibromas and papillomas. Roe deer fibropapillomatosis is present in Croatia as endemic disease, similarly to other European countries. It is a benign, in wild animals incurable disease, which depending on the location of the lesion can, with duration of the disease, cause severe or minor effects on the overall health and survival rate of the affected individual. From the results obtained, it is concluded that the majority of analyzed lesions contain both fibromatous and papillomatous characteristics, and therefore we find the term fibropapillomatosis suitable to describe this condition. Systematic survey and detailed examination of papillomavirus induced neoplasms is necessary for better understanding of its epidemiology.
