The acrocallosal syndrome is a rare congenital malformation syndrome with the main findings: agenesis of the corpus callosum, craniofacial dysmorphisms, mental retardation, polydactyly of the hands and/or feet. We report a patient with partial agenesis of the corpus callosum, dolichocephalus, broad and short nose, low-set and posteriorly rotated ears, pre- and postaxial polydactyly of feet, duplication with syndactyly of big toes, and postaxial hexadactyly of the left hand. Differential diagnosis and the genetic counseling are discussed.
