Poland anomalad: dermatoglyphic study in seven cases.

A dermatoglyphic study was made in seven patients with Poland anomalad. The ipsilateral hand showed great variability of the defect. The patterns were typical when the hand was synbrachydactylic. When there was only brachydactyly, there were peculiar configurations. Though the hand on the side of the defect may seem normal, some patterns are infrequent and on the "normal" hand on the other side, rare dermatoglyphic types were found.
