| Resumo: | Harlequin ichthyosis, also known as diffuse fetal keratosis, is an extremely rare andphenotypically severe hereditary skin disorder with autosomal recessive inheritance.This disease is caused by mutations in the adenosine triphosphate-binding cassettetransporter protein (ABCA12) gene. Prenatal ultrasonography and genetic analysisare important for prenatal diagnosis. Prenatal ultrasonographic diagnosis is difficult,and findings include ectropion plates, an abnormal auricular pinna, a flat nose,thickened skin with an armor-like appearance, thickened lips with sustained openmouth (fish mouth) status, and flexion fixation of the extremities. These are usuallyfound during the third trimester. Three-dimensional ultrasonography contributesto the evaluation of facial morphology. The prognosis is generally poor. Affectedneonates usually do not survive beyond the first days of life. A case of prenataldiagnosis of harlequin ichthyosis is presented. |
