Dermatomyositis following Treatment of Cancer

Abstract
A case of dermatomyositis following on treatment of a carcinoma with radio-therapy is reported. Dermatomyositis, an entity distinct from other connective tissue disorders and the carcinomatous neuromyopathies, occurs in 2 forms: Adult, often associated with malignancy; and Juvenile, not associated. The etiology may lie in some form of auto-immunity, but in adult cases with malignancy, the converse, a failure of immunity, could be the cause.
