case_images: (A) Edematous violaceous erythema on the face and periorbital tissues. (B) Erythema on the neck and upper chest. (C) Left hand displaying Gottron's papules. (D) The upper limb displays Gottron's sign. (E) Scaly plaques on the scalp. (F) Scaly plaques on the back. (G) Histology from the facial lesion revealed liquefaction of basal cells, edema of the superficial dermis, infiltration of lymphocytes around small vessels with nuclear dust. (H) Skin biopsy from a scaly erythema lesion on the shoulder showed hyperkeratosis, parakeratosis, neutrophil accumulation, disappearance or thinning of the granular layer, mild thickening of the spinous layer, infiltration of lymphocytes and histiocytes around small vessels in the superficial dermis and deposition of mucinous substances in the interstitium.

case_images: The physical examination revealed facial and periorbital edematous violaceous erythema ( Figure 1A ), erythema on the neck and upper chest ( Figure 1B ), Gottron's papules ( Figure 1C ), Gottron's sign ( Figure 1D ), scaly plaques on his scalp ( Figure 1E ) and back ( Figure 1F ). A skin biopsy from the facial lesion revealed liquefaction of basal cells, edema of the superficial dermis, infiltration of lymphocytes around small vessels with nuclear dust ( Figure 1G ). Another skin biopsy from a scaly erythema lesion on his shoulder showed hyperkeratosis, parakeratosis, neutrophil accumulation, disappearance or thinning of the granular layer, mild thickening of the spinous layer, infiltration of lymphocytes and histiocytes around small vessels in the superficial dermis and deposition of mucinous substances in the interstitium ( Figure 1H ).
