Abstract
We report a rare limb defect named as fibular aplasia, tibial campomelia, and oligosyndactyly
(FATCO) syndrome in a female monozygotic twin with a normal twin sister, presented
with anterior tibia pseudarthrosis, oligosyndactyly, and pes equinovarus. Radiographic
examination displayed the absence of left fibulae, anterolateral pseudarthrosis of
left tibia, and the absence of some metatarsus and phalangeal bones. Our case report
is the first to report that only one of the identical twins was affected by FATCO
syndrome, which is a significant finding because the pathogenicity of FATCO syndrome
is yet to be identified, and this clinical case may provide a new insight for discovering
the etiology of FATCO syndrome.
