Congenital hypertrichosis universalis is a rare autosomal dominant disease. We report the further development of a Greek girl, now aged 3 years, the first case associated with a balanced structural chromosomal aberration. She was described as a neonate by Sigalas et al. (1990). Her persistent generalized hypertrichosis is most excessive on the face, ears and shoulders. Her fine silky hair is of the vellus, not the lanugo type. The syndrome features are characterized, referring to nine further published case reports. It is distinguished from other types of congenital hypertrichoses, which have been described in the literature under different synonyms. To avoid confusion in the terminology, we propose to name this type of hypertrichosis Ambras syndrome in reference to the first documented family with congenital hypertrichosis universalis in the 16th century.
