- Definition
- Focal facial dermal dysplasias (FFDD) are rare ectodermal dysplasias, characterized by congenital bitemporal (resembling forceps marks) or preauricular scar-like lesions associated with additional facial and or systematic manifestations. 4 types of FFDD are described (FFDD I to IV). FFDD types II and III present with a variable facial dysmorphism including distichiasis (upper lashes) or lacking eyelashes, and upward slanting and thinned lateral eyebrows with a flattened nasal bridge and full upper lip. FFDD types I and IV are infrequently associated with extra-cutaneous anomalies.
