Abstract

Canine dermatomyositis is a skin and muscles inflammatory vasculopathy with cutaneous manifestations involving face, ears, tail and distal ends over bony prominences. Muscle involvement manifests itself in the form of muscles of the head, difficulty in swallowing, reduction of reflex of vomit and atypical gait. Canine dermatomyositis is classified into variant form or dermatomyositis-like. This report describes a case of dermatomyositis-like in a two-year-old female mixed-breed dog that presented ischemic necrosis of pinna and temporal and masseter muscle atrophy. In histopathological examinations performed with skin fragments of pinna, cephalic region and muscle samples (temporal and masseter), it was detected a perivascular dermatitis and folliculitis with poor cell interface, foci of folicular atrophy and muscle fibers with moderate dermal fibrosis confirming the diagnosis of dermatomyositis-like, relatively little described in brazilian veterinary dermatology.
