What is Dermatomyositis Skin Findings?

Dermatomyositis is an autoimmune disease in the group of idiopathic inflammatory myopathies, presenting with proximal symmetric muscle weakness and characteristic skin findings. It has two peaks, in children and in adults aged 40-60.

Skin findings often appear before muscle involvement. Heliotrope rash (purple-red erythema on the eyelids), Gottron papules (purple scaly plaques on the dorsum of the finger joints), V sign (on the front of the chest), and shawl sign (on the shoulders and upper back) are the typical findings of the disease.

It is very important to investigate underlying malignancies (especially ovarian, lung, pancreas, breast, gastric cancer) in adult dermatomyositis patients. The disease can be brought under control with early diagnosis and multidisciplinary treatment.

Symptoms

Purple-red erythema on the eyelids (heliotrope rash)
Purple plaques on the dorsum of the finger joints (Gottron papules)
Shawl-like erythema on the shoulders and upper back
V-shaped erythema on the front of the chest
Widening and hemorrhages in nail bed vascularization
Difficulty climbing stairs, combing hair (proximal muscle weakness)
Difficulty swallowing and shortness of breath (in advanced stages)

Risk Factors

Female gender
Specific age ranges (childhood 5-15, adulthood 40-60)
Genetic predisposition (HLA-DR3)
Viral infections (trigger hypothesis)
Underlying malignancy (in adults)
UV exposure (photosensitive skin findings)
Association with other autoimmune diseases
