title: Rudimentary polydactyly presenting as a claw.
abstract: A patient with a congenital claw-like lesion of the finger was studied to determine the nature of the tissue. A variety of biochemical techniques and histological examinations indicated that the lesion was an example of rudimentary polydactyly covered with stratum corneum rather than an accessory nail.
