“…Hyperkeratosis is more prominent on the lateral and plantar aspect of the toes, first and fifth metatarsal heads, heel and over the Achilles tendon, but lesions can be diffuse rather than focal. There are very few cases described in the literature, most of them associated with anti-Jo-1 antibodies (ASS), one case with anti-MDA5 antibodies, and in the author's experience, one patient with anti-PM-Scl antibodies 10,[16][17][18][19][20][21][22] . Inverse Gottron's sign: erythematous to violaceous macules or papules that may be accompanied by hyperkeratosis or ulceration.…”

Idiopathic inflammatory myopathies (IIMs), also known as autoimmune myositis, are a rare group of autoimmune disorders with a heterogenoeous spectrum of muscular and extramuscular involvement. IIM can be classified into several subgroups: dermatomyositis (DM), including clinically amyopathic DM, antisynthetase syndrome (ASS), immune-mediated necrotizing myopathy, inclusion body myositis, polymyositis, and overlap myositis (OM). Skin disease is a defining feature of DM, also present in AAS and OM. Lesions of DM are very varied but many share common histological features that are very useful for an early diagnosis of IIM when cutaneous involvement precedes other symptoms. Although the characteristic signs of DM are heliotrope rash, Gottron's papules, and Gottron's sign, there are a multitude of other cutaneous findings that can suggest a diagnosis of DM. Myositis-specific autoantibodies an myositis-associated autoantibodies have been identified in IIM. The former is only present in IIM and the latter can occur not only in IIM but also in other autoimmune disorders such as systemic lupus erythematosus, Sjögren syndrome, or systemic sclerosis. Myositis autoantibodies identify different clinical phenotypes, so they are very valuable in improving diagnosis and classification of IIM patients. This article first discusses the cutaneous findings of DM and then two particular phenotypes, MDA-5 DM, and AAS. Finally, OM according to myositis-associated autoantibodies is reviewed.

Dear Editors, the term "hiker's feet" was first used in 2017 to refer to hyperkeratosis of the toes and plantar surface of the feet, similar to "mechanic's hands", in the context of idiopathic inflammatory myopathies. Few cases of idiopathic inflammatory myopathies presenting with "hiker's feet"have been described, most of them associated with anti-Jo-1 antibodies, one with anti-MDA-5 antibody and the rest without any autoantibodies. There is no histopathologic description of this cutaneous finding. We report what is to our knowledge the first case of "hiker's feet" with its histopathologic findings in a patient with anti-PM-Scl-associated idiopathic inflammatory myopathy.A 74-year-old woman was referred to the Dermatology Department for the evaluation of corticosteroid-refractory skin lesions on her feet of 4 months duration. She presented with non-pruritic hyperkeratosis and erythema affecting the toes and the soles. She had a history of hypertension, dyslipidemia, chronic atrophic gastritis, and hypothyroidism on treatment with enalapril/hydrochlorothiazide, atorvastatin, cyanocobalamin, levothyroxine. Allergic contact eczema was excluded, and one year later psoriasis was diagnosed and she was started on acitretin. After 4 months, skin lesions had barely improved and the patient reported myalgias, dyspnea and constitutional syndrome so she was admitted to the hospital. Clinical examination revealed severe diffuse hyperkeratosis and erythema affecting the soles and lateral aspect of the feet and
