Resolution of anti-neutrophil cytoplasmic antibody-associated vasculitis after resection of gastric cancer.
We report a case of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis in a 62-year-old patient with gastric cancer. The myeloperoxidase-anti-neutrophil cytoplasmic antibody (MPO-ANCA) level was threefold above normal preoperatively. Vasculitis was seen on renal biopsy. Gastric resection revealed well-differentiated adenocarcinoma and vasculitis. The MPO-ANCA level returned to normal post-operatively. Although ANCA-associated vasculitis occasionally accompanies malignant tumors, this is the first documented case of concurrent gastric cancer-associated and ANCA-associated vasculitis, with post-operative resolution of the vasculitis.
