CARDONA ALVAREZ, José; VARGAS VILORIA, Marlene  and  PERDOMO AYOLA, Sandra. Periocular fibroblastic sarcoid in a donkey (Equus asinus ). Ces. Med. Vet. Zootec. [online]. 2013, vol.8, n.1, pp.161-170. ISSN 1900-9607.

In the present study we describe and discuss the clinical signs, gross and microscopic lesions, epidemiology, and diagnosis of a periocular fibroblastic sarcoid case in a donkey (Equus asinus) in Cordoba province (Colombia). The animal presented multiple nodular masses in the upper and lower eyelids and the medial angle of the left eye, with slight ulceration and diffuse skin lifting, characterized by tumor-like appearance, granulomatous, firm, and fibrous. Histopathological findings included epidermal hyperplasia, hyperkeratosis, long epithelial projections toward the dermis, and perpendicular orientation of fibroblasts relative to the basal membrane. The diagnosis was based on the clinical, epidemiological, and pathological findings.

Keywords : Donkey; fibroblastic sarcoid; eyelid.
