Purpura Henoch-Schönlein, distinct signs vs. Purpura Henoch-Schönlein, minimal signs

In both children a purpura Henoch-Schönlein is present. Bleedings and edemas of the intestinal wall usually explain the abdominal symptoms; but, in addition, an intussusception was present in both patients which is a dangerous complication of purpura Henoch-Schönlein. Right picture: In the picture at the bottom of the corresponding side the part of small intestine is visible at the bottom of the picture which is thickened by the intussusception, and parallelly arranged hematomas of the intestinal wall; the latter are large-faced in case of absent intussusception or beyond the zone with intussusception. Left picture: If the leading symptoms of this type of purpura are distinctly present, it is easy to consider a purpura Henoch-Schönlein and a possible complicating intussusception. Right picture: If the signs are insignificant on general examination of the child, it is much more difficult to consider at all a purpura Henoch-Schönlein and a complicating intussusception.

Both schoolchildren have an exanthema, either on the buttock or on the inner side of the left foot. Left picture: The exanthema of the right buttock is distinctly recognizable. Right picture: The exanthema at the inner side of the left foot is insignificant and barely visible. Left picture: The efflorescences are palpable and large-faced. Right picture: Petechial bleedings are present. Both patients had an abdominal symptomatology with colics and lower gastrointestinal bleeding. What disease is present?
