Congenitale cutane fibropapillomatose bij een warmbloedveulen

Abstract

In this report, clinical and histological findings of a rare case of a large congenital fibropapilloma on the forehead of a warmblood foal are reported. Surgical excision was curative and no recurrence was observed after nine months. The foal did not present any other abnormalities. Morphologically, the lesion was classified as a fibro-epithelial type of skin hamartoma. The fibrous component has thus far only been reported in pigs. Although fibropapillomas are common in adult animals and are associated with papillomavirus infection, this association has not been demonstrated in foals and piglets. Additionally, there were no histopathological indications of papillomavirus infection in the present study, nor could PCR reveal the presence of papillomavirus DNA.

“…Also, the present lesions had hyperplastic foci of sebaceous glands. Based on the histopathological findings and their similarity to previous reports of foals [4,11] and a piglet [8,10], fibropapillomatosis in the present case was considered as a hamartomatous change. cases.…”

“…A previously described case of congenital papillomatosis in a calf was suspected to be due to BPV infection during pregnancy [3]. On the other hand, congenital papillomatosis and fibropapillomatosis without evidences of PV infection have been reported in horses [4,11] and pigs [8,10]. This is a first case of bovine congenital cutaneous fibropapillomatosis without evidences of PV infection.…”

“…Congenital papillomatosis and fibropapillomatosis have been reported in horses [4,11] and pigs [8,10]. In those cases, no characteristic histological findings suggesting PV infection were observed [4,8,10,11].…”

“…Also, there were no evidences of PV infection by IHC or PCR examinations. Therefore, those lesions were suspected to be hamartomatous changes [4,8,11]. Furthermore, congenital papillomatosis in a horse involved the proliferation of matured sebaceous glands in the dermis [11].…”
