Werner syndrome associated with poorly differentiated thyroid carcinoma and systemic sclerosis-like skin manifestations: A case report

Abstract

ABSTRACT Werner syndrome (WS) is an autosomal recessive disorder characterised by premature ageing. WS patients often experience scleroderma-like manifestation including skin sclerosis and skin ulcer, making it difficult to differentiate WS from systemic sclerosis (SSc). Moreover, there is a high incidence of malignancy and arteriosclerosis-related disease in WS patients. We herein describe a 36-year-old woman with WS who had poorly differentiated thyroid carcinoma, one of the rare phenotypes of thyroid tumour. This case suggested the importance to distinguish WS from SSc and early diagnosis of malignancy.
