To the Editor.—
"Keratosis Punctata of the Palmar Creases," by Weiss and Rasmussen in the Archives (1980;116:669-671), presents an interesting but often described entity (as those authors, too, have emphasized).1 In 1970, Smith and Jetton2 reviewed 125 consecutive outpatients at Charity Hospital in New Orleans. They found 47 patients who had punctate lesions of the palms, 29 had only creases involved and 11 had involvement outside of the creases as well. Seven had keratoses, but not in the creases at all. The lesions were mostly bilateral. Here, too, there was no history of arsenic ingestion and no demonstrable history of keratoses in the family. When they combined those patients who had keratoses and those with discrete pits in the palmar creases, the authors found an astounding incidence of these characteristics in 69% of black patients and 42% of white patients. These authors also established a statistically significant association
