Abstract

Clinical signs and features include:

Bimodal incidence pattern—childhood and then age 50–70s; four to ten new cases per million; more common in women

Associated with internal malignancy in about 25 % of cases, especially adenocarcinoma of ovary, lung, and gastrointestinal tract in Western countries and nasopharyngeal carcinomas in South East Asia, Southern China, and North Africa; the diagnosis of dermatomyositis may be made prior to, concurrently, or after the diagnosis of malignancy; age-appropriate malignancy surveillance is recommended

Muscle symptoms: symmetric proximal muscle and truncal weakness that develops relatively slowly over the course of weeks to months, occasionally associated with myalgias and muscle tenderness early in the disease course. It is atypical for muscle disease to precede skin manifestations.
