Digital necrosis: a paraneoplastic syndrome.

We describe a 62-year-old man who presented with digital necrosis as part of a clinical picture which resembled Wegener's granulomatosis. However, an open lung biopsy revealed adenocarcinoma of the lung. To our knowledge he is only the 5th reported patient with lung cancer presenting with digital necrosis. The unusual association of digital necrosis and internal malignancy is discussed.
