title: A case of Werner's syndrome associated with osteosarcoma.
abstract: We described a case of Werner's syndrome associated with osteosarcoma. A 37-year-old Japanese man was diagnosed as having Werner's syndrome by the presence of juvenile cataracts, skin sclerosis and hyperpigmentation of the feet, high-pitched voice, characteristic bird-like appearance of the face with beak-shaped nose, thinning of the entire skin and hyperkeratoses on soles, hyperlipemia, hyperuricemia, diabetes melitus, and the mutated responsible gene (WRN). He had a 3-month history of a tumor on his left forearm. Histologically, the tumor included four histological patterns; a malignant fibrous histiocytoma-like, a desmoid-like, a dermatofibrosarcoma protuberans-like, and a chondrosarcoma-like pattern. Tumoral osteoid formation was also found in the tumor. Therefore, the tumor was diagnosed as osteosarcoma.
