Unusual patterns of chronic photodamage through clothing.

Recent cancer statistics estimate that the yearly incidence of cutaneous malignancies in the United States is similar to the incidence of all other cancers combined. Ultraviolet radiation-induced photodamage of the skin plays a large role in the growth of these skin cancers. The case of a 47-year-old white man with peculiar patterns of actinic skin damage on the anterior chest and back is presented, and the relationship of these findings with his choice of clothing is reviewed. The transmission of ultraviolet radiation through clothing fabrics is addressed, with recommendations for the use of clothing as an effective form of photoprotection.
