To the Editor:
In two papers1,2 presented in 1965, we reported results which support the findings recently recorded in the Archives of Dermatology by Epstein and Pinski.3 In our series of 12 cases of porphyria cutanea tarda, three had hemoglobin values exceeding 17.5 gm/100 cc and six had hemoglobin values exceeding 16 gm/100 cc. The most outstanding case was that of a white Australian aged 64 who was seen in October 1962. He had a 12 month history of symptoms of cutaneous porphyria and had had two episodes of acute abdominal discomfort. In addition to fragility and blistering of the light exposed areas he was developing sclerodermiform changes of the head, neck, and upper trunk which were rapidly extending when first seen. Following intravenous chelation therapy with sodium calciumedetate in the Queen Elizabeth Hospital, Adelaide, his condition improved steadily with objective softening of all the sclerodermiform areas.
