title: [Paraneoplastic digital necrosis: a case report].
abstract: BACKGROUND
  Digital necrosis is a frequent vascular disease. Its very often reflects arterial disorders of macro or mirocirculation. Paraneoplastic digital necrosis is rare, however.
  
  
  OBJECTIVE
  Report a new case of paraneoplastic digital necrosis
  
  
  METHODS
  Our patient was a 62-year old diabetic female patient with a history of total thyroid ablation at 50 year old. She presented with bilateral digital necrosis of the second, third and fourth fingers. During her recovery, we have found a biological inflammatory syndrome and abdominal echography revealed a metastatic liver. Radiological investigations in search for the primitive tumour were negative. The patient was referred to a specialized center for a palliative chemotherapy.
  
  
  CONCLUSIONS
  Etiologies of digital necrosis are various, mainly iatrogen, professional, toxic, atheroma or systemic disease. In case of no evident cause, explorations should be gone to detect underlying malignancies.
