Leiomioma pulmonar primario

Primary lung leiomyoma is a rare benign tumor of mesodermal origin, that accounts for approximately 2% of all benign lung tumors. Since it was first described by Forkel in 1910, at least 150 cases have been reported in the literature. A review of the subject is made regarding the case of an oligosymptomatic postmenopausal woman, with the finding of a solid lung lesion, associated with a vascular malformation, in whom the initial biopsy reported a spindle cell tumor, for which she was taken for a right upper lung lobectomy and whose definitive pathological diagnosis was primary pulmonary leiomyoma. This case is presented due to its low incidence and the little literature on this type of benign tumor lesions.
