Osteopathia striata-pigmentary dermopathy-white forelock syndrome

Osteopathia striata-pigmentary dermopathy-white forelock syndrome (also known as osteopathia striata with pigmentary dermopathy and white forelock) is an extremely rare genetic disorder characterized by a distinctive combination of skeletal, skin, and hair abnormalities. The condition is defined by osteopathia striata (linear striations visible on X-rays of the long bones and other skeletal structures), pigmentary skin changes (hypopigmented and hyperpigmented macules or patches affecting the skin), and a white forelock (poliosis, a patch of white or depigmented hair at the front of the scalp). Additional features that have been reported in some affected individuals include facial dysmorphism, hearing loss, and other skeletal anomalies. The skeletal striations are typically identified on radiographic imaging and represent areas of increased bone density running longitudinally through the metaphyses and diaphyses of long bones, as well as the pelvis and other flat bones. The pigmentary skin findings may be present from birth or early childhood and can vary in distribution and severity. Currently, there is no specific curative treatment for this syndrome. Management is supportive and symptom-based, potentially involving dermatologic care for skin findings, audiologic monitoring if hearing loss is present, and orthopedic follow-up for any skeletal complications. Genetic counseling is recommended for affected families.
