(See also Overview of Vascular Bleeding Disorders.) Senile purpura causes ecchymoses and results from increased vessel fragility due to connective tissue damage to the dermis caused by chronic sun exposure, aging, and drugs. Purpura refers to purplish cutaneous or mucosal lesions caused by hemorrhage. Small lesions (< 2 mm) are termed petechiae, and large lesions are termed ecchymoses or bruises. Senile purpura typically affects elderly patients as their dermal tissues atrophy and blood vessels become more fragile. Patients develop persistent dark purple ecchymoses, which are characteristically confined to the extensor surfaces of the hands and forearms.
