A case with drug-related ANCA-positive vasculitis

Abstract

Main causes of drug-related antineutrophil cytoplasmic antibody (ANCA)-positive vasculitis are antithyroid drugs. It is known that ANCA- positive vasculitis occurs after long term use of the drugs and develops in 4-6.5 percent of the patients. Herein, we present a female patient with propylthiouracil (PTU)-related ANCA- positive vasculitis, mimicking appendicitis and familial mediaterian fever (FMF), which developed after long-term drug usage.
