Four cases with ectrodactyly, ectodermal dysplasia, cleft lip/palate syndrome: Clinical evaluation and management and literature review

A rare syndrome is ectrodactyly-ectodermal dysplasia-cleft lip/palate (EEC) syndrome, which may present with lobster claw deformity. The main clinical characteristics indicate involvement of ectodermal and mesodermal tissues, including mesoaxial and longitudinal defect of distal extremity, cleft lip and palate, and developmental defects of ectoderm derives.
