Large bruises that occur with minimal trauma or spontaneously as a direct result of medications that thin the blood.
Widespread ecchymoses resulting from an inherited or acquired defect in blood clotting factors, such as hemophilia or liver disease.
Long-term steroid use leads to fragile blood vessels, causing characteristic flat, irregular, purple bruises on the forearms and hands with minimal trauma.
A life-threatening condition presenting with widespread ecchymoses and hemorrhagic necrosis due to systemic activation of coagulation.
A connective tissue disorder characterized by hyperextensible skin and easy, extensive bruising due to blood vessel fragility.
A rare reaction to heparin causing well-demarcated, painful, hemorrhagic plaques that progress to necrosis, often at injection sites.
A catastrophic condition of DIC and skin necrosis, presenting as large, rapidly spreading areas of hemorrhagic necrosis.
Vitamin C deficiency leading to impaired collagen synthesis, characterized by perifollicular hemorrhage (bleeding around hair follicles), corkscrew hairs, and ecchymoses.
Deposition of amyloid in blood vessel walls causes fragility, leading to characteristic "pinch purpura" or spontaneous periorbital ecchymoses ("raccoon eyes").
A rare complication of warfarin therapy, presenting as painful, hemorrhagic skin lesions that progress to necrosis, typically on fatty areas like the breasts or thighs.
The most common inherited bleeding disorder, causing easy bruising, nosebleeds, and prolonged bleeding after procedures.
