Examples of cutaneous paraneoplastic syndromes include dermatomyositis (which causes skin rashes and muscle weakness) and pyoderma gangrenosum (which is a rapidly enlarging, painful ulcer). Other paraneoplastic conditions that involve the skin include Sweet’s syndrome, which causes skin lesions along with sudden onset fever, and the Leser–Trélat sign, which includes the presence of multiple seborrheic keratoses.
