X-linked dominant genodermatosis causing staged skin lesions following Blaschko's lines, primarily affecting females.
Full Definition
Incontinentia pigmenti is a rare X-linked dominant disorder caused by mutations in the IKBKG gene, typically lethal in males. Affected females present with four classic stages of skin lesions: vesicular (birth to 4 months), verrucous (2-6 months), hyperpigmented (3 months to adulthood), and hypopigmented (adolescence). The condition may also involve dental, ocular, central nervous system, and hair abnormalities requiring multidisciplinary management.
