Abstract:
Incontinentia pigmenti (IP) is an uncommon X-linked, dominantly inherited disorder due to a mutation in the NEMO (NF-kappaB essential modulator) gene on the X chromosome. IP mostly occurs in female infants, it is usually embryonic lethal in males. The mechanisms for survival of affected males are explained by the presence of an extra X chromosome (Klinefelter's syndrome), hypomorphic mutations, and somatic mosaicism. We report here a rare case of incontinentia pigmenti in a 13-year-old boy with Klinefelter's syndrome, NEMO gene mutation, and whorled, hyperkeratotic, hyperpigmented, linear lesions along the lines of Blaschko on the trunk and leg.
