title: Malignant change in a solitary hamartoma of the lung. A case report.
abstract: A case report of a malignant hamartoma of the lung observed in a 36-year-old housewife was presented. The hamartoma was non-chondromatous (fibromyomatous), located beneath the pleura of the left upper lobe. The malignant lesion corresponded to anaplastic carcinoma of the lung. A review of the literatures on the malignant hamartoma of the lung revealed rare incidences of the tumor, but hamartoma and hamartomatous lesions of the lung should be regarded as one of the histopathological backgrounds where pulmonary carcinoma may arise.
