Bleomycin toxicity simulating metastatic nodules to the lungs.

Pulmonary nodules may develop following bleomycin therapy, a previously undescribed entity that may simulate metastatic disease. Two asymptomatic patients are reported with nodules that developed following low dose bleomycin treatment for testicular tumors. One patient had previously documented pulmonary metastases that had resolved after chemotherapy. The other patient had nodular-appearing densities on routine chest examination without a history of previous metastatic lung involvement.
