Over the past 33 years the authors have treated 12 cases of skull metastasis from @entity259 , accounting for 2.5% of a total of 473 cases of @entity259 . A study of these 12 cases revealed the following characteristics. The mean age of the @entity1 was 60.4 years and the predominant incidence was in the seventh decade of life. The incidence of skull metastasis from @entity259 was higher among @entity1 than among @entity1 . The primary sign was a soft @entity5 resting on the skull. The @entity5 were rich in vascularity with osteolytic changes in the skull. The average period from diagnosis of the @entity259 until thyroidectomy was 14.3 years, and until discovery of the skull metastasis was 23.3 years. The clinical course was thus very long. The most frequent histopathological presentation was @entity53917 . Such lesions were morphologically well differentiated, with little pleomorphism and atypism, but detailed examination showed infiltration into the vascular lumen or capsule. The mean survival time in these @entity1 was 4.5 years from the time of diagnosis. The prognosis in this lesion was relatively poor, considering its long clinical course.
