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 called petechiae, and large lesions are called ecchymoses or bruises.
Senile purpura typically affects older people as their dermal tissues atrophy and blood vessels become more fragile. People develop persistent dark purple ecchymoses, which are characteristically confined to the extensor surfaces of the hands and forearms.
New lesions appear without recognized trauma and then resolve over several days, leaving a brownish discoloration caused by deposits of hemosiderin. This discoloration may clear over weeks to months or may be permanent. The skin and subcutaneous tissue of the involved area often appear thinned and atrophic.
Dermaka cream is very effective on purpura.
