Full Text

A 2-year-old boy presented with frequent complex partial seizures since two months of age and global developmental delay. He had classical cutaneous lesions of NCM [Figure 1]. NCM is a nonfamilial neurocutaneous syndrome of poor neurological prognosis. There are large cutaneous melanocytic naevi and CNS melanin deposits due to defective migration of melanoblasts from neural crest with frequently seen bathing suit pattern skin lesions.[1] MRI shows bilateral amygdala T1 hyperintensities due to paramagnetic properties of melanin which is commonly described with NCM.[1],[2] In this context with the typical cutaneous and imaging findings, there are no other differential diagnosis.{Figure 1}
