Abstract
Lung cancers are diagnosed at a metastatic stage in 40% to 50% of cases. Skeletal muscle metastases are rare and usually discovered at autopsy. We report 3 cases of skeletal muscle metastasis. Muscular metastasis revealed the cancer in one patient. The metastases were asymptomatic in all patients. The diagnosis was confirmed histologically in one case and by radiography in the other 2. The evolution was characterized by tumor progression and death after 1–7 months.
