A 17-year-old boy presented with multiple striated erythema and papules at birth.The erythema was fragile,easily damaged,and often healed leaving hypopigmented patches.The right first and second finger nails were hypoplastic.Generalized linear or whorled hyperpigmented patches gradually developed,and some yellow-pink papules enlarged into plaques with age.Multiple papillomatous papules appeared during childhood,which were mainly distributed in the perioral region.Skin examination revealed widespread linear or whorled hyperpigmented patches intermingled with scattered hypopigmented patches and yellow-pink plaques,which were mainly located in the trunk.Multiple papillomatous papules were observed in the perioral region,mandibular region,and right popliteal fossa.Skin biopsy showed epidermal parakeratosis,diminished dermal thickness,increased blood vessel density in dermal papillae,upward migration of subcutaneous fat layer known as "fat herniation".A diagnosis of focal dermal hypoplasia was made.
