In Doctor Keith Hammond's brief report concerning skin dimples and rubella1 in the February issue of Pediatrics he states that no one has reported a peculiar, discrete, deep dimpling of the skin over the patella and certain bony prominences as a physical finding of early infancy.
This statement is somewhat unusual in that this phenomena has been well described by Doctor Caffey and is well illustrated in his textbook of Paediatric X-ray Diagnosis, fourth edition, where these characteristic dimples have been seen in infants suffering from prenatal bowing which commonly regresses during early childhood.
