Focal dermal hypoplasia in a male.
Focal dermal hypoplasia (FDH) is a rare mesoectodermal dysplasia syndrome characterized by cutaneous, skeletal, dental, ocular and soft-tissue defects. An X-linked dominant mode of inheritance with lethality in male subjects has been proposed. Only around 30 cases of FDH have been reported in male subjects. Live born affected males are mosaic for mutations in PORCN gene . We present the mosaic pattern of FDH in a young boy.
