Abstract
The interstitial pneumonia (IP) associated with myeloperoxidase anti-neutrophil cytoplasmic autoantibody (MPO-ANCA) showed characteristic histology dominated by usual IP pattern. We showed a 94-year-old woman, whose prognosis was poor by severity of IP by MPO-ANCA associated vasculitis. The median age at diagnosis of IP by MPO-ANCA associated vasculitis was over 60 years, with a male predominance. Most patients died related to respiratory insufficiency. Our case would be the oldest patient in IP by MPO-ANCA associated vasculitis in the literature.

Summary
The interstitial pneumonia (IP) associated with myeloperoxidase anti-neutrophil cytoplasmic autoantibody (MPO-ANCA) showed characteristic histology dominated by usual IP pattern. The age of patients in IP associated with MPO-ANCA may be related poor prognostic course, since they suffer the other significant sickness and their symptoms may be masked by their holding diseases [1]-[3]. IP generally occurs after the age of 60 years and is more prevalent in men. (2016) Interstitial Pneumonia in a 94-Year-Old Woman with MPO-ANCA Positive Vasculitis. D. Usuda et al The majority of the studies have showed higher prevalence and incidence rates among men and with increasing age, especially after 75 years. We show a 94-year-old woman with IP associated MPO-ANCA and discuss the relation between elderly patients and the disease characters
