Werner's syndrome associated with malignancies: five case reports with a survey of case histories in Japan

Abstract

We present 5 cases of Werner's syndrome associated with malignancies and a survey of 26 cases in the Japanese literature. Though tumors of mesenchymal origin have been reported in Werner's syndrome, 14 of the 31 cases cited in this paper developed carcinomas. Carcinoma of the thyroid gland was relatively high in frequency. The significance of carcinomas in Werner's syndrome should be further investigated.
