Dermatomyositis related to a male germ cell carcinoma: a case report

ABSTRACT

Dermatomyositis is an autoimmune disorder that affects mainly muscles and skin. In some cases it may be associated to neoplasms occurring before the diagnosis of cancer. Its relation to germ cell tumor is not well documented, so we describe a case of a patient with history of muscle weakness and cutaneous rash that preceded cancer for 6 months. Dermatomyositis must remind of a possible occult neoplasm and its remission may follow the treatment of the tumor.
