Familial canine dermatomyositis

35 Familial canine dermatomyositis


Lesions associated with dermatomyositis usually present as alopecia, erythema, scaling, ulceration and crusting. As with many vascular diseases, the extremities and prominences such as the face, tail, pinnae and limbs are mainly affected, so oral, footpad and nail lesions may all be present. Ulceration may develop in more severely affected cases that may also be hyper- or hypopigmented. In general, this is a non-pruritic disease unless there is secondary pyoderma. Temporal muscle atrophy is the most common initial symptom of myositis. Other signs of myositis include dysphagia, facial palsy, stiff gait and a generalized weakness.

Clinical findings in this case were:

Examination of the skin revealed focal, well-demarcated patches of shiny-appearing alopecia over the bridge of the nose, forehead (Fig. 35.1) and hindquarters (Fig. 35.2). There were two slightly crusted erosions over the convex aspect of the left pinna and a focal crusted erosion above the left eye (Fig. 35.1).
