Introduction: Immunoglobulin A vasculitis (formerly known as Henoch Schonlein Purpura) is the most common pediatric vasculitis, which occurs typically at the age of 3-15 years. Mononucleosis, group A Streptococcus, Campylobacter and Mycoplasma are some of the common infectious causes of immunoglobulin A vasculitis. Immunoglobulin A vasculitis is a clinically diagnosed disease. Most common clinical features include nonthrombocytopenic nonpruritic palpable purpura, gastrointestinal involvement, arthritis or arthralgia and renal involvement. Biopsy of skin and/or gastrointestinal lesions con rm the diagnosis, although this is not necessary. Immunoglobulin A vasculitis is a self-limiting disease, which resolves spontaneously. Steroids can be used for the treatment of moderate to severe disease and for the prevention of renal complications. Prognosis relies upon various factors among which involvement of kidneys dictates poor prognosis and requires close follow up. Case Presentation: We are presenting a case of immunoglobulin A vasculitis in a 39-year-old German male following in uenza virus infection. The infectious agent that cause immunoglobulin A vasculitis in our patient was In uenza A virus. Biopsy of the skin lesion con rmed the diagnosis of immunoglobulin A vasculitis in our patient. The patient responded to steroids and his skin and GI ndings resolved. Conclusion: Our case report adds to the literature of medicine by describing in uenza virus as a cause of immunoglobulin A vasculitis in young adult patients. Considering immunoglobulin A vasculitis after in uenza and outside of the typical age of 3-15 years, can help to make earlier diagnosis and prevent complications.
