ORUEZABAL MORENO, M. J.  y  BURON FERNANDEZ, M. R.. Vasculitis de pequeño vaso en un paciente con un adenocarcinoma de colon. Oncología (Barc.) [online]. 2005, vol.28, n.6, pp.43-49. ISSN 0378-4835.

Oncologic patients can develop a vasculitis during the follow-up, whose diagnosis is difficult due to the rarity of the process. Notwithstanding it is of vital importance because the high mortality rate when it is not treated, and also because its diagnosis avoids staging mistakes when interpreting the clinical manifestations secondary to the tumor. We report a case of p-ANCA-positive small vessel vasculitis associated to an isolated lung hemorrhage in a patient with colon adenocarcinoma, demonstrating the importance of recongnizing the enigmatic and variable clinical presentation of the systemic vasculitis, an infrequent and badly known syndrome.
