ABSTRACT
BACKGROUND/PURPOSE:
Only a few studies have compared frequencies of photodermatoses among different races and skin types. This is an extension of a study performed by Kerr and Lim and evaluates the frequency of photodermatoses in African-Americans compared with Caucasians in the same institution during an 8-year period.METHODS:
Retrospective chart review was performed, including dermatology clinic charts from October 2004 to August 2012 with International Classification of Diseases, Ninth Revision diagnostic codes related to photodermatoses.RESULTS:
We identified 229 patients with photodermatoses. Of these, 138 (46.6%) were African-American and 63 (42.2%) were Caucasian. Statistically significant differences in the distribution of photodermatoses in African-Americans and Caucasians, respectively, were as follows phototoxic drug eruption (0.7% and 15.9%, P < 0.0001), phytophotodermatitis (0% and 6.3%, P = 0.009), polymorphous light eruption (PMLE) (86.2% and 54%, P < 0.0001) and porphyrias (0% and 7.9%, P = 0.003).CONCLUSION:
Combined with data from Kerr and Lim, this is the largest study of photodermatoses in African-Americans to date. Congruent to former studies, photodermatoses do occur regularly in dark-skinned individuals. Overall, the frequency of photodermatoses in African-Americans and Caucasians are similar; however, PMLE occurs more commonly in African-Americans, and porphyias and phototoxicity occur more commonly in Caucasians.Key words
