title: [Two cases of metastasizing benign leiomyomatosis from myoma uteri].
abstract: Case 1. A 50-year-old woman was referred to our hospital because of multiple bilateral small round lesion on chest radiography. She had undergone total hysterectomy for myoma uteri at the age of 33. She underwent thoracoscopic tumor excision at left lung. The lesion was proved benign. Right side lesions were laterly excised using thoracotomy. Case 2. A 49-year-old woman was referred to us because of two ovoid lesion at left lung area of chest radiography. She also had undergone total hysterectomy for myoma uteri at the age of 37. She underwent tumor extirpation using thoracotomy. All samples of two patients revealed, pathologically, lesions were consisted of benign spindle-like calls similar to those of myoma uteri. Therefore, we consider these lesions were pulmonary metastasis of myoma uteri. Myoma uteri has certain potential of metastasizing to the lung, in spite of benign disease.
