Dermatomyositis - Cause - Diagnosis - Symptoms - Treatment

Dermatomyositis cause, diagnosis, symptoms and treatment. Dermatomyositis is a type of connective-tissue disease characterized by muscle and skin inflammation. A similar condition is called polymyositis when the symptoms occur without any skin manifestations.

Dermatomyositis is connective-tissue disease that is characterized by inflammation of the muscles and the skin.

What Is Connective Tissue?
Connective tissue supports the organs and structures of the body. Certain disorders involve connective tissue.

Dermatomyositis- Gottron's papules hand - ( Photo-Picture)
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 ( Photo-Picture)
Photo-Picture of "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 - ( Photo-Picture )
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 ( Photo-Picture)
Photo-Picture of Gottron's sign, seen in dermatomyositis. Violet-colored inflammation over the knuckles is an important diagnostic finding in dermatomyositis, since other skin conditions produce more redness.

Paronychia - candidial ( Photo-Picture )
Candida paronychia produced periungual erythema, edema and nail fold maceration.

Dermatomyositis - Heliotrope Face Rash ( Photo-Picture)
Inflammation of the connective tissues (dermatomyositis) 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

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

Dermatomyositis is an inflammatory muscle disease (myopathy). It primarily affects the skin and muscles but may affect other organ systems of the body.

Polymyositis & Dermatomyositis
Polymyositis is characterized by inflammation and degeneration of the muscles; dermatomyositis is polymyositis accompanied by skin inflammation, from Merck Manual.

Myopathy is the medical term for muscle disease. There are many causes of muscle disease, such as infection, muscle injury due to medications, inherited diseases affecting muscle function, disorders of electrolyte levels, and thyroid disease. Some of these disorders, such as polymyositis, dermatomyositis and inclusion body myositis, develop when the immune system attacks muscles, from ACR.
