Abdominal anaphylactoid purpura symptoms?

Abdominal symptoms of Henoch Schonlein purpura are common, most patients have gastrointestinal involvement, which can appear as the first symptom. Abdominal pain is caused by the blood and liquid in the blood vessels entering the intestinal wall. It is often paroxysmal colic or dull pain. It can be very severe and the position is often not fixed. It is mostly in the left and right lower abdomen or around the umbilicus, sometimes throughout the whole abdomen. The attack lasts for 1 to 2 hours, but generally without abdominal muscle tension. The tenderness is mild, and it can be accompanied by nausea, vomiting, diarrhea and melena.

Due to irregular intestinal peristalsis, can lead to intussusception, palpable mass, more common in children. Intestinal perforation may occur occasionally. If there is no skin purpura, it is often misdiagnosed as "acute abdomen", such as acute appendicitis, intestinal obstruction, visceral perforation, peritonitis, acute localized enteritis.
