A rare syndrome mimicking scleroderma: Werner syndrome

OpenAlex İngilizce

Werner syndrome (WS), also known as adult progeria, is a premature ageing syndrome that can manifest itself with grey hair, hair loss, diabetes mellitus, hyperlipidaemia, hypertension, skin disorders, ocular cataracts, myocardial infarction, osteoporosis, and stroke, especially after puberty. Physical examination findings similar to systemic sclerosis may be seen. Therefore, it may mimic this disease as misleading. A 43-year-old female patient was admitted to our clinic with a pre-diagnosis of systemic sclerosis complaint of skin hardening up to the ankle. In the first physical examination, there were wrinkles and thinning of the lip, suggesting systemic sclerosis in the facial appearance. On her capillaroscopy, there was tortuosity and an old focus of microhemorrhage. She had a history of diabetes mellitus and chronic osteomyelitis. When all symptoms, clinical findings, and antibody results were combined, it was thought that the patient might have WS. WS was diagnosed with homozygous c.2221 C>P p.R741*(rs763089663) positive in genetic analysis. It is known that WS creates a predisposition to malignancies, and most patients die secondary to malignancies. Therefore, early diagnosis becomes essential. Early diagnosis is of vital importance both to prevent complications and to delay treatment. In particular, systemic sclerosis-like findings of this syndrome may cause delays in diagnosis. For this reason, small clues suggesting WS in the clinic should be well known and well defined.
