Extensive symmetric truncal aplasia cutis congenita without fetus papyraceus or macroscopic evidence of placental abnormalities.

Aplasia cutis congenita is a rare disorder characterized by localized absence of skin at birth. Type V in Frieden's classification, which is associated with fetus papyraceous or placental infarcts, occurs as a large cutaneous defect on the trunk and extremities. The patient we report had a lesion affecting the trunk and extremities symmetrically, with no family history of the disorder or chromosomal abnormalities. In our opinion, despite the absence of fetus papyraceous or placental infarct, this patient's condition can be classified as type V.
