Migrating hair: a case confused with cutaneous larva migrans.

Pili migrans is an unusual skin condition in which a hair shaft migrates under the surface of the skin and mimics the parasitic infection, cutaneous larva migrans. If the migrating hair is located on the sole of the foot, it represents a foreign body from an exogenous source. We present a 3-year-old boy with bilateral pili migrans on the soles of his feet, acquired after running around in his socks while at his mother's beauty salon. This case highlights a distinctive presentation of a foreign body penetration of the skin that can easily be confused for and should be differentiated from the parasitic disease, cutaneous larva migrans.
