Osteopathia striata associated with familial dermopathy and white forelock: evidence for postnatal development of osteopathia striata.

Osteopathia striata and a macular, hyperpigmented dermopathy were found in a Caucasian woman and her two daughters. Sequential radiographs in one daughter showed that the bone lesions were not present during infancy but developed during early childhood. The skin lesions were not those most often associated with osteopathia striata, but appeared tgo be a unique dermatosis, which also included a hypopigmented forelock. A son had neither osseous nor ectodermal lesions. These abnormalities appear to represent a new syndrome, which is inherited with X-linked or autosomal dominant transmission.
