[Dermatomyositis and small-cell lung cancer : fortuitous association or paraneoplastic syndrome?].
Dermatomyositis, an inflammatory muscle disease probably related to dysimmunity, is associated with character skin eruptions. Dermatomyositis is often associated with cancer (15 to 40% of cases depending on the series). All histological types and all cancer localizations observed in the general population can be associated with dermatomyositis. We report the case of a patient with dermatomyositis who developed small-cell lung cancer. There have been few descriptions of this association in the literature. Certain clinical features of dermatomyositis would be predictive of its paraneoplastic nature. Prognosis is very poor. Treatment is basically dictated by the underlying neoplasia.
