We present a case that mimicked multisystem pyoderma gangrenosum with cutaneous ulceration, renal sparing, and antineutrophil cytoplasmic antibody negativity. Although antineutrophil cytoplasmic antibody is positive in approximately 90% of cases of granulomatosis with polyangiitis, its negativity should not exclude the diagnosis. Additionally, pyoderma gangrenosum-like cutaneous ulcers should prompt consideration of granulomatosis with polyangiitis, especially in the context of multisystem disease presentation. This case underscores the importance of maintaining a high suspicion for granulomatosis with polyangiitis in patients presenting with cutaneous ulceration and respiratory tract disease. <\/jats:p>","DOI":"10.1177\/2050313x241304229","type":"journal-article","created":{"date-parts":[[2024,12,11]],"date-time":"2024-12-11T09:11:08Z","timestamp":1733908268000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Granulomatosis with polyangiitis mimicking multisystem pyoderma gangrenosum: A case report"],"prefix":"10.1177","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-9160-3740","authenticated-orcid":false,"given":"Amanda","family":"Gormley","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Green","sequence":"additional","affiliation":[{"name":"Division of Clinical Dermatology and Cutaneous Science, Department of Medicine, Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,12,11]]},"reference":[{"key":"bibr1-2050313X241304229","unstructured":"Garlapati P, Qurie A.
