What is your diagnosis? (37)


The histopathological study evidenced lesions compatible with a chronic, parasitic, crusty, hyperplasic dermatitis. The inflammatory cell infiltrate, mostly eosinophilic, and the presence of mites amongst the keratin debris suggests it is a case of mange, in cattle it can be caused by Psoroptes spp. or, less probably, by Sarcoptes spp.  which is zoonotic and usually involves the face, but can extend to the body. A third species, Chorioptes spp., usually is distributes in the limbs.   You can check out similar lesions and their histopathological appearance in a case we published a while ago in a lamb: Sarcoptic mange in a lamb.
