Neuropathy in erythropoietic protoporphyrias.
Peripheral neuropathy (PN) has rarely been described as a complication of erythropoietic protoporphyria (EPP). We describe three episodes of PN and the electrophysiologic findings in two patients with EPP. PN is seen in patients with EPP and hepatic failure and raised free erythrocyte protoporphyrin or serum protoporphyrin levels and is identical to that seen in acute intermittent porphyria. Recognition is important because of the good eventual prognosis.
