Defective blastogenesis of postnatally diagnosed type VI sirenomelia in a young primigravida: A case report.

Sirenomelia is a rare lethal multi-systemic birth malformation in which the two lower limbs are replaced with a rotated single midline tail-like limb. Several hypotheses try to explain this syndrome, with the most prominent theories being the "vascular steal hypothesis" and the "defective blastogenesis hypothesis." We report a case of a baby with sirenomelia who had a single femur and a single tibia, which classify the case as type VI on Stocker and Heifetz classification.
