title: Multiple benign lung tumors.
abstract: Multiple benign pulmonary nodules are rare and are from a variety of etiologies. Infectious causes, such as histoplasmosis, tuberculosis, or parasitic infections, usually require biopsy for confirmation. An interesting entity, benign metastasizing leiomyoma, is rare but occurs from a low-grade leiomyoma that most commonly spreads from the uterus.
