Localized Paroxysmal Pruritus in Multiple Sclerosis / 대한피부과학회지

ABSTRACT

Paroxysmal itching is a rare symptom in multiple sclerosis and it was first reported in 1975 by Osterman and Westerberg. It has been suggested that paroxysmal itching may be due to the activation of axons in CNS via abnormal synapses between demyelinated axons. Carbamazepine, phenytoin, and ibuprofen are known to be effective in the treatment of paroxysmal itching. We report a case of paroxysmal itching of 4 months' duration in a 41-year-old female with multiple sclerosis who suffered from severe paroxysmal itching on the left side of her neck and chest. The itching did not respond to carbamazepine, but it was partially controlled with ibuprofen.
