Piezogenic papules

Piezogenic papules are small, skin-colored papules that appear on the heel upon weight bearing. These papules are typically painless and cause no medical harm. They are seen in individuals of all ages, but are more common in adults.

Causes

Piezogenic papules are caused by herniation of subcutaneous fat into the dermis. This herniation is thought to be due to increased pressure in the heel during weight bearing. Obesity and Ehlers-Danlos syndrome are known risk factors for the development of piezogenic papules.

Symptoms

Piezogenic papules are typically asymptomatic. However, some individuals may experience pain, especially during weight bearing. The papules disappear when the pressure is relieved.

Diagnosis

The diagnosis of piezogenic papules is made clinically, based on the characteristic appearance of the papules on the heel during weight bearing. No specific laboratory tests or imaging studies are needed for diagnosis.

Treatment

Treatment is typically not necessary for piezogenic papules, as they are usually asymptomatic. However, if the papules are painful, treatment options include weight loss, use of supportive footwear, and injection of a corticosteroid into the papule.
