Abstract
Background

The frequency of photodermatoses in African Americans has not been well characterized.

Objective

To evaluate the frequency of photodermatoses in African Americans in an academic medical center during a 7-year period. This was compared with that observed in Caucasians seen during the same period.

Methods

A retrospective chart review of 2200 dermatology clinic charts from August 1997 to September 2004 was performed. Charts of patients with International Classification of Diseases, Ninth Revision diagnostic codes related to photodermatoses were included.

Results

Two hundred eighty patients with photodermatoses were identified: 135 (48%) African Americans, 110 (40%) Caucasians, and 35 (12%) patients of other races. In African Americans and Caucasians, the frequency of diagnoses was as follows: polymorphous light eruption (PMLE) (67.4% and 41.1%, respectively), systemic phototoxicity (13.3%, 10.7%), chronic actinic dermatitis (11.1%, 7.1%), porphyrias (0.7%, 21.4%), solar urticaria (2.2%, 8%), and other (5.2%, 10%). There was a statistically significantly higher proportion of African Americans with PMLE (P < .0001) compared with Caucasians. There was a statistically significantly higher proportion of Caucasians with porphyrias and solar urticaria (P  < .001 and = .03, respectively) compared with African Americans.

Limitations

This study was a retrospective analysis.

Conclusion

Photodermatoses occur regularly in African Americans. With the notable exceptions of PMLE, porphyrias, and solar urticaria, the frequency of photodermatoses in African Americans was similar to that in Caucasians.
