Editor,Dermatomyositis (DM) is an idiopathic inflammatory myopathy characterized by an inflammatory infiltrate primarily affecting the skeletal muscle and skin. It is the commonest of the idiopathic inflammatory myopathies of childhood, comprising 85% of cases. It has an annual incidence estimated to range between 1.9 and 4.1 per million children. Euwer proposed a classification in which DM skin manifestations are subdivided into pathognomonic, highly characteristic and compatible skin lesions. The most common and peculiar manifestations include Gottron's papules, Gottron's sign and heliotrope rash. Recognition of cutaneous and histopathologic findings in DM is essential for prompt and accurate diagnosis and treatment of DM.A 2‐year‐old girl presented with a four‐month history of recurrent palmar lesions. A hand‐foot‐and‐mouth disease was eliminated because of persistence of the lesions. The patient was treated in a second time with topical corticosteroids for presumptive diagnosis of acropustulosis. In the same time, the patient presented with a lameness and was plastered in a context of fall. Dermatological examination revealed focal hyperkeratosis overlying the palmar faces of interphalangeal and metacarpophalangeal joints (Fig. ). Similar lesions were observed on the helix and the big toe. After removing the plaster, the patient still limped and complained of a painful ankle. No fever
