A small depression in the skin on the sole of the foot. Depressions may also be seen on the palm of the hand (palmar pits). They are usually pink or flesh-colored and range from 2 to 3 mm in diameter and 1 to 3 mm in depth. Plantar pits are often more visible after a brief soaking of the hands or feet. This condition is associated with basal cell nevus syndrome, which is a hereditary syndrome associated with the development of basal cell carcinoma.
