Purpuric : Petechiae
Tiny 1-2 mm, initially purpuric, non-blanchable macules resulting from tiny hemorrhages.
Purpura can be differentiated from pigmented lesions by color. Pigmented lesions are usually brown in color in comparison to the violaceous color of purpuric lesions.
Petechiae, ecchymoses, and palpable purpura do not blanch because blood has leaked outside the vessels into the surrounding skin.
