A case is reported in which a fibrosarcoma developed 20 years after irradiation of a pituitary chromophobe adenoma. This rare lesion, like most of the other documented postirradiation pituitary sarcomas, was a combination of fibrosarcoma and pituitary adenoma. These lesions tend to behave in a characteristic fashion, with onset after a long latent interval following irradiation, growth to a large size, and failure to metastasize.
报告了一例垂体嫌色细胞瘤放疗20年后发生纤维肉瘤的病例。这种罕见的病变，与其他大多数已记录的放疗后垂体肉瘤一样，是纤维肉瘤与垂体腺瘤的组合。这些病变往往表现出特征性的行为方式，即在放疗后很长的潜伏期后发病，生长到很大的尺寸，且不发生转移。
