The unusual case of a patient on peritoneal dialysis who progressively
developed onychodystrophy of the hands 2 months after Acinetobacter p
eritonitis had been reported. The nail disease consisted of acute pseu
doclubbing, elkonyxis, severe Beau's lines and onychomadesis and showe
d spontaneous recovery within 4 months. Although reminiscent of severe
Beau's lines and reflex sympathetic dystrophy, this observation shows
a peculiar nail disorder of unknown cause.
