[Dermatomyositis as a complication of a metastatic melanoma-- case report and review of the literature].

In nearly 60% of men over 50 years of age, dermato-/polymyositis is induced by malignancies. Till now, 9 patients with melanoma-induced dermatomyositis have been reported in the literature. Here we report on a patient suffering from classic pelvic and pectoral girdle proximal weakness, typical heliotrope rash, increased serum CPK values, and biopsy-proven myositis, who died from metastasizing melanoma one year later.
