[JNUS]

Clinical History :

One week ago, the mother of this 4-year-old girl noted small red dots on the child's legs, which the primary pediatrician diagnosed as bug bites. The lesions became larger, and a schoolteacher confronted the mother about what she thought were bruises on the child's legs. Concerned, the mother brought the child to a dermatologist, and biopsy was performed; however, the mother states that no diagnosis was made. Now, nearly hysterical, the mother brings her daughter to the emergency department and complains that the rash looks worse and that the child refuses to walk. The girl is afebrile, appears well, and she is able to ambulate. What is the diagnosis?

Hint
Children with this idiopathic syndrome often complain of abdominal pain. Skin Leisons are palpable but do not blanch.
