The lesion (see image below) is characteristic of a neuro-cutaneous syndrome. The lesion is often described as light, hyperpigmented macules with irregular borders. They can be characterised as ‘birthmarks’ or represent an underlying syndrome. This syndrome often has other cutaneous manifestations, such as freckling in skin folds. Patients can also develop ocular complications.
