Dermatomyositis

Dermatomyositis is a muscle disease that involves inflammation and a skin rash. It is a type of inflammatory myopathy.

Dermatomyositis, Gottron's papule

Red, thickened, scaly skin over the knuckles (Gottron's sign) associated with dermatomyositis, an autoimmune disease of the skin and muscles.

Dermatomyositis, Gottron's papules on the hand

This violet-colored inflammation (erythema) over the knuckles is caused by Dermatomyositis. Other skin conditions produce more redness, while the color of this lesion is violet. There may also be inflammation in the muscle tissue.

Dermatomyositis, heliotrope eyelids

This photograph demonstrates the sign "heliotrope eyelids" in which the eyelids develop a brown (violaceous - rather than red) color. Heliotrope eyelids and Gottron's papules on the knuckles are characteristic findings in dermatomyositis.

Dermatomyositis on the legs

The appearance of purple (violaceous) plaques on the knees may be associated with dermatomyositis. Typically, most lesions associated with other diseases are red (erythematous).

Dermatomyositis, Gottron's papule

This is Gottron's sign, seen in dermatomyositis (an inflammatory disease of the muscles and skin). Violet-colored inflammation over the knuckles is an important diagnostic finding in dermatomyositis, since other skin conditions produce more redness.

Paronychia, candidial

Candida paronychia produced periungual erythema, edema and nail fold maceration.

Dermatomyositis, heliotrope rash on the face

Dermatomyositis, a connective tissue disease, typically produces a reddish-purple (violaceous) rash. The rash is named after the tendency of plants to grow toward the sun (heliotropic) and is characteristic of dermatomyositis.
