THE SIMULTANEOUS occurrence of a disease process in identical twins is of interest to students of medicine and genetics. The familial incidence of pernicious anemia and achlorhydria has been well recognized in Europe and in this country.1 Though the occurrence of pernicious anemia has been reported in identical male and female Caucasian twins,2 we could find no instance of its report in Negro twins or of its simultaneous occurrence in any one pair of twins. Brief reports with less confirmatory evidence of pernicious anemia in twins have been made by other authors.3
The following is a report of pernicious anemia occurring simultaneously in identical Negro female twins.
REPORT OF CASES
—The first of the twins, J. M. S., a 72-year-old Negro woman, was admitted to the George Washington University Medical Division of Gallinger Municipal Hospital on Oct. 24, 1950, and was discharged on Dec. 1,
