Onicodistrofia lupoide simétrica canina: relato de caso

Symmetric lupoid onychodystrophy, or lupoid onychitis, is a multifactor immune-mediated onychopathy. The aim of the present study is to report the occurrence of lupoid onychitis in a two year-old mongrel dog helped at the Small Animal Dermatology Service of Sao Paulo State University Veterinary Hospital, in Botucatu, São Paulo. The animal presented lameness, onycholysis in five digits, paronychia, onychomadesis, nail softening and leuchonychia, as well as melicerous crusts in interdigital spaces and nailbeds.
