To the Editor:—
With reference to our article "Porphyria, Diabetes and Their Relationship" which was published in the Archives of Dermatology, Vol. 83, No. 5, May, 1961, the sentence on p. 719, paragraph 1, line 12, which states, "We are of the opinion, however, that the characteristic bluish-gray tint of porphyric skin is due to the presence of iron" is in error.In this sentence we have inadvertently left the impression that we believe that iron alone is responsible for peculiar hyperpigmentation of the skin in porphyria and hemochromatosis. The sentence should read, "However, we believe that the characteristic bluish-gray tint of porphyric skin is due to the presence of both iron and melanin pigment, the melanosis resulting from the capacity of iron for binding sulfhydryl groups."
