Gastrointestinal manifestations of henoch-schoenlein purpura

摘要

A 43-year-old Hispanic male was admitted to the hospital with a 2-week history of epigastric pain, hematochezia, rash, and joint pain in his elbows and knees. The pain was non-radiating, without nausea, vomiting, or exacerbating or alleviating factors. Two weeks prior to the onset of these symptoms he had developed flu-like symptoms that resolved without treatment. His past medical history was significant for hypertension; however, he had no personal or family history of gastrointestinal, hematological, or autoimmune disease. He had been taking hydrochlorothi-azide and irbesartan for his hypertension. He did not smoke or drink alcohol. On admission, he was afebrile without any abnormalities in his vital signs or cardiopulmonary examination. Physical examination was notable for palpable petechial and purpuric lesions on his legs, arms, and periumbilical region; epigastric tenderness was elicited upon deep palpation, and his elbows and knees were tender to touch (Fig. 1). Stool occult blood was positive.
