A 56-year-old woman complained of nausea, abdominal pain, and bloody diarrhea 10 days prior to the day of consult in our institution. Her abdominal pain worsened and was accompanied by joint pain for several days, prompting a consult at our hospital. Physical examination revealed strong rebound tenderness in the right lower abdomen and the presence of multiple palpable purpuras in the lower extremities (Figure C). Laboratory test results revealed a high C-reactive protein level of 1.21 mg/dL, as well as normal renal function and urinary findings.
