Clinical Background:

Over a 3 month period, this 60 year old woman noticed the appearance of erythematous plaques on the hands, elbows and periorbital areas with weakness, diffuse arthralgia, fatigue, and weight loss.
She was therefore referred to our Department for further investigations: physical examination revealed characteristic heliotrope (violaceous) periorbital erythema and erythematous plaques (Gottron papules) overlying the knuckles (on pre-existing white areas of vitiligo) and the elbows.
The CK (creatine kinase) and other muscle enzymes were always within the normal range during follow-up despite muscle weakness, pain and focal evidence of myopathy on EMG.
Interstitial pulmonary fibrosis was found on chest X-rays, CT scan and respiratory function tests.
