Pseudosyndactyly

Pseudosyndactyly refers to a mitten hand deformity of hands and feet in dystrophic epidermolysis bullosa. It may also be seen in amniotic band syndrome. It should not be confused with true syndactyly which is the actual and complete fusion of fingers.

In pseudosyndactyly fingers are fused by thin membrane of skin which can be released later. Antenatally it may be misinterpreted as syndactyly. Pseudosyndactyly involves only the distal portion of the digits, whereas syndactyly includes the base of the digits.
