[Nodular vasculitis in the current practice of phlebology]

In current phlebological practice nodular vasculitic lesions are described as being characterised by hypodermal perivascular inflammation. The aetiology is diverse: in this article hypodermatitis of varicose and postphlebitic origin, both of which are due to basic vein disorders and which are certainly the most often encountered phlebopathies in daily practice, are studied and then there is a further study of acute and sub-acute nodular hypodermatitis which in practice represents a differential diagnosis to the former but are less frequently encountered. Finally, other cases of hypodematitis due to yet more rare causes are recalled. Rare though these may be, the practicing physician must not fail to consider them when a patient who has come to see him presents with suspect nodular lesions of the lower limbs.
