Petechiae

Excerpt

Petechiae are pinpoint non-blanching spots that measure less than 2 mm in size, which affects the skin and mucous membranes. A non-blanching spot is one that does not disappear after applying brief pressure to the area. Purpura is a non-blanching spot that measures greater than 2 mm. Petechial rashes are a common presentation to the pediatric emergency department (PED). Non-blanching rashes can be a great cause for concern for parents and physicians alike. Therefore, careful assessment and evaluation are necessary to formulate a sensible management plan.
