A 40-year-old woman presented with facial edema and painful skin lesions involving the hands. On examination, heliotrope rash [Figure 1]a, hyperkeratotic ulcerated papules on the knuckles [Figure 1]b and erythematous, flat-to-raised keratotic lesions involving the palmar aspect of the interphalangeal joints [Figure 1]c were noted. A diagnosis of dermatomyositis (DM) was made with clinical features and raised muscle enzymes. | Figure 1: Clinical photograph showing heliotrope with periorbital edema (a) and Gottron's sign over dorsal aspect of hand (b), flat-to-raised lesions involving palmar aspect of the fingers in a distribution “inverse” of the classic Gottron's papules/sign (c, black arrow) and fingertip scars suggestive of healed ulcers (c, white arrow)

Gottron's papules are pathognomonic of DM. Inverse Gottron's sign/papules [Figure 1]c, due to vasculopathy are a rare but specific cutaneous finding in DM, usually associated with digital ulceration, interstitial lung disease, and anti-MDA5 autoantibodies.[1],[2],[3]
Anti-MDA5-positive DM occurs in 7.2% of adults and 9.7% of children, respectively, in the Indian subcontinent. Cutaneous vasculopathic features such as cutaneous ulceration, and periorbital edema as seen in the index may indicate a worse poor prognosis in adults with anti-MDA-5 DM.[4]
