【Abstract】 A case of focal dermal hypoplasia presenting as incontinentia pigmenti is reported.A 30-year-old woman presented with hyperpigmentation,hypopigmentation and atrophy macules all over the body since birth.The lesions follow Blaschko’s lines.She also had syndactylies of the third and fourth toes of the right foot since birth.Biopsy specimens showed dermal hypoplasia,attenuation of the dermis,and upward extension of the fat tissue.Verhoeff and acid orcein-Giemsa stains showed a remarkable diminution of fine elastic fibers from the papillary to upper reticular dermis,whereas those of the mid dermis were intact.Differential diagnosis must be made with incontinentia pigmenti.更多还原
