Nodes on the frontal and parietal bones of the skull, giving it a buttocklike shape, seen in congenital syphilis.
Parrot described his nodes in the skull as resembling nates or buttocks; Frederick Treves (1853-1923) commented “They have been termed natiform elevations by M. Parrot, from their supposed resemblance when viewed collectively, the nates. To the English mind they would rather suggest the outlines of a hot cross bun!”

Progrés médical, Paris, 1879, 7: 269-269.
