Purpura simplex is increased bruising that is due to fragile blood vessels.

Purpura simplex is extremely common. The cause is not known. Some doctors think it may be a feature of many disorders, but others think it is a normal variation.

Aspirin and drugs that prevent blood clots (for example, warfarin), low body weight, prior use of corticosteroid drugs, and sun exposure may increase the risk of purpura simplex.

This condition is not serious, and no treatment is needed. However, sometimes doctors recommend that people avoid taking aspirin and aspirin-containing drugs.
