[Multiple pulmonary leiomyomatous nodules: benign metastasing leiomyoma?].

Pulmonary smooth muscle lesions are rare explaining their imperfect understanding. Two cases of multiple pulmonary leiomyomatous lesions in patients who previously underwent surgery for benign uterine leiomyoma are reported. Literature was reviewed to know if the controversial question of benign metastasising leiomyomas could be resolved. Therapeutic possibilities of this pathology are also discussed.
