The verrucous stage is more likely to be confused with epidermal nevi and warts than the pigmentary stage. The verrucous stage usually lasts up to one year, and the pigmentary stage often fades by adolescence. Cavernous Hemangiomas can often be almost completely treated with the pulsed dye laser. In Sturge-Weber Syndrome, a Port Wine Stain is seen over the Trigeminal nerve distribution and glaucoma, seizures, and retartdation may be associated. Lamellar Ichthyosis is associated with a steroid sulfatase deficiency and can be identified as decreased steroid sulfatase activity.
Cavernous hemangiomas are too deep to be completely treated by the pulsed dye laser.
X-linked ichthyosis is associated with the steroid sulfatase deficiency. Lamellar ichthyosis may present as a collodion baby.
