Correct answer: C — Undertake age-indicated and risk-directed malignancy evaluation

The best answer is “Undertake age-indicated and risk-directed malignancy evaluation”. Dermatomyositis, especially with anti-TIF1-gamma, carries increased malignancy risk. Screening is individualized by age, phenotype and antibody profile while muscle and swallowing disease is treated. Dysphagia also requires urgent aspiration-risk assessment because respiratory and swallowing complications can become more immediate than muscle weakness.
