Piezogenic papules are protrusions of fat that form within the subcutaneous tissue of the skin. They are typically found on the heels or wrists.

Signs and symptoms

They present as multiple small or large bumps characteristically on the heels and wrists. Most are asymptomatic and pain is rare, although some may present with pain before the bumps are noticed. They may feel soft or firm.

Cause and risks

The bumps are caused by pressure. There may be an association with Prader–Willi syndrome, and around a third of individuals with Ehlers–Danlos syndrome may have them. Risk factors include obesity, flat feet, athletics, figure skating, and long-distance running.

Diagnosis

Diagnosis is based on appearance. If present in a child it may appear similar to juvenile aponeurotic fibroma.

Treatment

Generally, no treatment is required. They usually disappear when pressure is relieved; avoidance of prolonged standing, taping foot, compression stockings, heel cups, padding devices.

Epidemiology

Piezogenic papules are relatively common; in one small population-based study, the prevalence was found to be 76%. The same study found that it was not unusual to demonstrate the bumps when pressing a person's wrist.

History

The term was first coined by W. B. Shelley and Rawnsley, who first described them in 1968.
