Bita Abbasi Medical Student, School of Medicine, Mashhad University of Medical Sciences, Mashhad, Iran. 2015 09 28 Descriptive case report of a 42-year old woman with coetaneous vasculitis, and severe abdominal pain, which was led to diagnostic laparotomy. These presentations are probably as a side effect of Methocarbamol injection. This is the first report according to our literature search (PubMed, google scholar, ISI web of knowledge, ProQuest, MD consult, Science Direct, SCOPUS) about Methocarbamol related vasculitis from 1966 since now. Vasculitis is not a known side effect of Methocarbamol. This case indicates, likely the potential for development of vasculitis with this medication. https://acta.tums.ac.ir/index.php/acta/article/view/3722 https://acta.tums.ac.ir/index.php/acta/article/download/3722/3697
