Abstract
Phacomatosis pigmentokeratotica is characterized by the coexistence of nevus sebaceus, papular nevus spilus and associated neurologic abnormalities. We report a case of phacomatosis pigmentokeratotica in a 28-year-old male who presented with palmar-plantar dysesthesia and ipsilateral brain hemiatrophy. As a characteristic neuroimaging finding of the disorder, we found multiple hypointense lesions involving the ipsilateral hemisphere.
