title: Leiomyomatous lung lesions: a proposed classification.
abstract: A case of multiple pulmonary leiomyomas is presented. In a review of the literature, a confusing array of rare diseases all pertaining to multiple leiomyomas was found. These were reduced to three entities: leiomyomatosis in women, metastatic leiomyoma in men and children, and multiple pulmonary fibroleiomyomatous hamartoma occurring in anyone. The leiomyomatous diseases in women are related to uterine leiomyomas and they are hormone-sensitive. This is of great prognostic importance. The classification, definitions, and discussion should prove helpful in understanding these rare multiple diseases.
