The congenital ectopic nail is very rare and usually present as an ectopic abnormal nail alongside the normal fingernail. Ridder described in 1992 the "congenital palmar nail syndrome" sharing a palmar ectopic nail, a loss of flexion and a small distal phalanx on x-ray. We report a case of a congenital palmar nail syndrome of both little fingers on a boy 13 years old.
