To the Editor.—
In January 1972, our interest in piezogenic pedal papules1-5 was rekindled when a 21-year-old marine undergoing evaluation for pes planus was noted to have multiple soft, skin-colored protuberances on the medial sides of both heels. The protuberances were visiblePiezogenic pedal papules are visible when pressure is placed on the foot (top). Protuberances disappear when pressure is relieved (bottom). only when the patient was standing (Figure, top) and disappeared when pressure on the patient's heels was relieved by lifting his feet or by sitting (Figure, bottom).Suspecting (1) that Cohen et al2 were correct in their comment, "it is likely that painful peizogenic papules are not as rare as the paucity of information about them would imply," and (2) that piezogenic pedal papules are not necessarily symptomatic, we examined 412 consecutive patients for the presence of piezogenic pedal papules at the new Podiatry Clinic, U.S.
