Pulmonary benign metastasizing leiomyoma: Case report of late occurrence in postmenopausal patient

Introduction: Pulmonary benign metastasizing leiomyoma (PBML) is a rare condition that occurs most commonly in young women of reproductive age some years after hysterectomy. The aim of this study was to report a PBML case which occurred 33 years after hysterectomy in a postmenopausal patient. Case report: A 59-year-old female diabetic patient, G2P2A0, with dyslipidemia, a non-smoker and ex-alcoholic (quit in the 90s), with pulmonary symptoms was referred to the health service. A chest computed tomography (CT) revealed multiple pulmonary nodules. A previous history of hysterectomy at 26 years of age led to a diagnostic hypothesis of PBML. The patient underwent segmentectomy of the largest nodule (measuring 1.2 x 0.9 cm) located in the left lung. Histopathology and immunohistochemistry studies confirmed the diagnosis of PBML. Conclusion: The patient is currently in good physical condition (regression of previous pulmonary symptoms) and scheduled for clinical follow-up. A new chest CT will be performed in 6 months. (author)
