Prostate cancer underlying acute, definitive dermatomyositis: successful treatment with radical perineal prostatectomy.

The idiopathic inflammatory myopathies are systemic autoimmune diseases characterized by chronic inflammation leading to progressive weakness of the proximal muscles. In 7-66% of cases of adult dermatomyositis different malignant tumours can promote the difficult cascade mechanisms at the cell level, leading to rapid weakness of skeletal muscles [1]. We report on a patient with all characteristic signs of acute, severe dermatomyositis associated with a low-grade, low-stage prostate cancer cured by radical perineal prostatectomy.
