- Abstract
Background Papillomatosis is a viral disease manifested with benign cutaneous growths (skin epithelium hyperplasia) in different body parts which is encountered in cattle, goat, dog, rabbit, horse, rodent and also in human. The purpose of the present study is to detect the histo-morphological changes of cutaneous papillomatosis in indigenous cattle. Methods Ten (10) random samples from skin lesions of warts were collected from adult indigenous cattle (10 cattle) that were diagnosed as cutaneous papillomatosis by clinical examination at Veterinary Teaching Hospital, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh. For gross observations, location of appearance of warts, color and size was taken into consideration. Immediately after collection of sample, they were preserved in Bouin's fluid followed by dehydration, clearing and infiltration and finally embedded by paraffin wax. Then samples were sectioned using rotatory microtome and stained with Harris's Haematoxylin and Eosin Y to facilitate microscopic study. Results The results of present study revealed that cutaneous papillomas were mostly located on the head and neck, around eyes, under the chin and perineal region in indigenous cattle. Grossly, warts in cattle are bumpy or cauliflower-like masses of various sizes and numbers that projected from the skin having grey, rough, scaly, and dry surface. When incised, its cut surface has an external layer-keratinized epithelium and an internal core-moist white connective tissue. Histopathological changes indicate hyperplastic features of the affected skin layers of epidermis. Further, the microscopic analysis also revealed orthokeratotic hyperkeratosis, acanthosis and down word hyperplasia, fibrovascular area, keratohyalin granules and koilocytes at different layers of the affected skin. Conclusion The results of this present study might be useful for the classification and treatment of this common malady based on its histological changes.
