摘要
A 71-year-old woman presented with chest pain, cough, and back pain. A chest roentgenogram showed multiple nodular shadows in both lungs. She was diagnosed with granulomatosis with polyangiitis (GPA). The multiple nodular shadows in both lungs regressed spontaneously in a few months. There are few reports of spontaneous regression of GPA, and the underlying mechanism is unclear. Neutrophil extracellular traps (NETs) have been recently shown to be involved in GPA. NETs may also be related to the natural regression of GPA. (C) 2021 The Japanese Respiratory Society. Published by Elsevier B.V. All rights reserved.
