A rare, neonatally lethal chondrodysplasia with histological character
istics was first described in 1978 and the authors named the condition
fibrochondrogenesis. Here we report the eighth published case of fibr
ochondrogenesis. This was identified in a population of 1 158 067 cons
ecutive livebirths, so we can assume that this figure should be the mi
nimal prevalence for livebirths.
