Petechiae are superficial,pinhead-sized (less than 3 mm),round,hemorrhagic macules,bright red at first,then brownish or rust colored.They are most commonly seen in the dependent areas,are evanescent, occur in crops,regress over a period of days, and most often imply a disorder of platelets, usually thrombocytopenia.They may also be a sign of a blood vessel disease such as scurvy

Anaphylactoid purpura Henoch-Schonlein Purpura (HSP)is characterized by intermittent purpura, arthralgia (74%to 84%),abdominal pain (61%to 76%),and renal disease (44%to 47%).Typically,palpable purpura appears on the extensor aspects of the extremities,which become hemorrhagic within a day and start to fade in about 5 days
