Does a history of eczema predict a future basal cell carcinoma?

Dyer et al. (this issue) assess the risk of new basal cell carcinoma (BCC) in the Veterans Affairs topical tretinoin chemoprevention trial, which included individuals with a history of at least two prior keratinocyte carcinomas. In addition to known risk factors for a future BCC, such as number of prior BCCs, a history of eczema and lower education levels were also associated with greater risk.
