Cutaneous manifestations of thrombocytopenia including petechiae, purpura, and ecchymoses. (A) Petechiae: flat, red, pinpoint lesions often found in groups in dependent areas. (B) Purpura: purple discoloration caused by confluent petechiae in either the skin (dry) or mucosa (wet). (C) Ecchymoses: nontender areas of bleeding into the skin with extravasated blood and breakdown of heme pigments causing red, purple, green, and yellow coloration.
