Metastatic uterine leiomyomata. A case report

Abstract

Pulmonary metastases from uterine leiomyomata are extremely rare and unpredictable, despite the high frequency of uterine leiomyoma. Review of the literature reveals seven previous examples of pulmonary metastasis from uterine leiomyomata; other cases may exist, but they were not considered because there was little evidence to distinguish them from leiomyosarcoma. The case we report is unusual in: 1) its prolonged course of 21 years, 2) its lack of pulmonary symptoms, despite extensive multiple nodules; and 3) the cystic change of the multiple lesions, which mimicked cystic lung disease.
