Peripheral sensory neuropathy associated with short-term oral acitretin therapy

A 57-year-old female patient with widespread chronic plaque psoriasis and a 32-year-old male patient with severe oral lichen planus are reported, who developed sensory symptoms in the extremities 3 and 4 months after the onset of oral acitretin therapy, respectively. Both patients showed clinical and electrophysiological evidence of a sensory peripheral neuropathy, which completely resolved 2 and 2.5 years after discontinuation of oral acitretin administration, respectively.
