DERMATOMYOSITIS

• Dermatomyositis (DM) is a long term inflammatory disorder which affects muscles.
• Symptoms generally are a skin rash and worsening muscle weakness over time.
• Other symptoms may include weight loss, fever, lung inflammation, or light sensitivity.Complications may include calcium deposits in muscles or skin.

Clinical Features:
Skin

• One form in which the rash presents itself is called as “heliotrope” (a purplish color) or lilac, but may also be red. It can occur around the eyes along with swelling, but also occurs on the upper chest or back what is called the “shawl” (around the neck) or “V-sign” above the breasts and may also occur on the face, upper arms, thighs, or hands.
• Another form in which the rash presents itself is called as “Gottron’s sign” which are red, sometimes scaly, papules that erupt on any of the finger joints (the metacarpophalangeal joints or the interphalangeal joints).All these rashes are made worse by exposure to sunlight, and are often very itchy, painful, and may bleed.

Muscles

• People with DM experience progressively worsening muscle weakness in the proximal muscles (for example, the shoulders and thighs).Tasks that use these muscles: standing from sitting, lifting, and climbing stairs, can prove challenging for people with DM
