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.

Tuberculosis has a high prevalence in Tunisia, but pulmonary embolism is rarely reported in Mycobacterium tuberculosis infection. We describe 3 cases of pulmonary embolism associated with severe pulmonary tuberculosis. Pulmonary embolism occurred within 2 to 13 days of pulmonary tuberculosis diagnosis. Clinical, bacteriological, and radiological evolutions were noted within 6 months for pulmonary tuberculosis, but controlling the international normalized ratio was difficult in 2 cases, and low-molecular-weight heparin was prescribed for 6 months in one case. The association between tuberculosis and pulmonary embolism is rare, but it should be systematically investigated, particularly in those with severe pulmonary or disseminated tuberculosis.
