Solar Lentigos are small, flat, brown circular spots, which are benign and are not related to moles. They are a type of freckle and are related to sun exposure. Some individuals in Portland get large numbers of them on the face and backs of the hands as they get older. If a brown spot is changing colors, size or shape it should be evaluated. These evaluation services are available at Norris Dermatology in Portland.
