title: Leiomyoma of the lung--report of a case.
abstract: A case of leiomyoma of the lung appearing in a 28-year-old female with a history of supracervical hysterectomy for uterine leiomyoma 10 years previously is reported. She had no symptoms but chest X-ray film showed a single nodule in the right upper lobe which slowly increased in size over a 3 year interval. At thoracotomy the tumor measured 4 cm in size and was sharply demarcated from the lung parenchyma without any connection with the bronchial tree. Histological findings proved this tumor to be a leiomyoma with no atypical cells or mitoses showing a close resemblance to uterine leiomyoma. Metastasizing uterine leiomyoma is very rare. Because these leiomyomas behave clinically as a low grade malignancy despite a histologically benign appearance, careful long term follow-up is necessary.
