Transient bullous dermolysis of the newborn

Transient bullous dermolysis of the newborn (TBDN) is a skin condition that presents in newborns. It is characterized by blister formation secondary to even mild trauma.[1]:558

A subtype of dystrophic epidermolysis bullosa,[2] it is rare, usually inherited condition that presents with characteristic blisters at birth which resolve between six months and one year of age.[3]

Blisters may cover the entire body including the mouth, and as they heal, they may leave some mild scarring. In addition, nail changes may occur which can persist to adulthood.[3]

It is associated with COL7A1.[4]

The condition was described by Ken Hashimoto in 1985.[5][6]
