Neurocutaneous melanosis is congenital melanocytic nevus with neurological manifestations. We report a 4-year-old female child presenting with hyperpigmented and nodular skin lesion associated with developmental delay and convulsions. The child had multiple brownish-black nevi on the face and chest and giant melanocytic nevi on thoraco-abdomen, back, and gluteal region. Computed tomography scan of the brain showed calcification in the pons, right cerebellar hemisphere, and left medial temporal lobe. Skin biopsy done from nodular hyperpigmented site was suggestive of melanocytic nevi. Electroencephalogram showed multifocal epileptiform discharges.
