Hypokalemic periodic paralysis is an uncommon disease that has rarely been reported in blacks. Historical, clinical, and pathological findings in three black patients, in addition to those previously reported in the literature, suggest that the spectrum of the disease is identical in both blacks and whites. Considering the disease as either different or unknown in the black population is probably not justified.
