Adult-Onset Immunoglobulin A Vasculitis (IgAV) Presenting in a Middle-Aged Indian Male Patient.

Immunoglobulin A vasculitis (IgAV) is a small vessel vasculitis that mainly affects the skin, gastrointestinal tract, and kidneys.  We present a case of a middle-aged male patient who presented to the emergency department with lower chest pain, colicky abdominal pain, and painful petechial rash. His inflammatory markers and IgA were raised with mild proteinuria. Abdominal CT and endoscopy revealed gastrointestinal involvement, and immunofluorescence skin biopsy confirmed IgA deposition in the dermal vessels. He responded clinically to oral steroids, and his inflammatory markers trended down. After six days, he was discharged.
