 en Case Report - Coexistence of two neurocutaneous syndromes: Tuberous sclerosis and hypomelanosis of Ito
Muhammed K, Mathew Jenny


Tuberous sclerosis complex (TSC) and hypomelanosis of Ito (HI) are two uncommon neurocutaneous syndromes and their coexistence is extremely rare. An epileptic child presented with progressively increasing multiple hypopigmented macules arranged in a linear and whorled pattern along the lines of Blaschko over the trunk and limbs, characteristic of HI. He also had facial angiofibromas, ash-leaf and confetti macules and shagreen patches. Magnetic resonance imaging of the brain showed cortical tubers and subependymal nodules; which are diagnostic of TSC. The TSC defining loci have been mapped to Chromosome 9q34 (TSC1) and 16 pl3.3 (TSC2). There is no common genetic background for HI, but mosaicism of 9q33 locus has been documented. As per our knowledge, this is the second case of association of TSC with HI in a four-year-old child.
