We report a rare case of dermato-neuro syndrome in a 71-year-old man with a known history of scleromyxoedema. The patient initially presented with encephalopathy which quickly progressed to generalised tonic–clonic seizures and coma. While his presentation fits with other, although rare, cases of dermato-neuro syndrome, it is imperative to rule out lethal, more common causes of altered mentation. Due to the rarity and difficulty in diagnosis of dermato-neuro syndrome, there is a significant debate regarding the optimal management as there are no standardised treatment protocols. In our case, the patient was successfully treated with plasmapheresis resulting in improved neurologic function.
