She developed peg-G-associated vasculitis 11\u2009days after initially receiving peg-G. Management and outcome: Although various blood and culture tests were required to rule out other vasculitis syndromes and infections, her symptoms spontaneously disappeared without any treatment other than discontinuation of the causal drug.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>G-CSF-associated vasculitis is occasionally accompanied by severe complications such as aortic dissection and aneurysm formation.
