Mrs. Britton is a 34-year-old patient who presents to the office with complaints of skin rashes. You have noted a group of lesions larger than 0.5 cm, with an elevated area of psoriasis. This is an example of a:

A. A pustule is a small elevation of the skin that contains pus, typically smaller than 0.5 cm. B. A macule is a flat, discolored area of skin that is less than 0.5 cm in diameter, so it does not fit the description of elevated lesions larger than 0.5 cm. C. A papule is an elevated, solid lesion that is less than 0.5 cm in diameter; lesions larger than this would not be classified as papules. D. A patch is defined as a flat, non-palpable lesion larger than 0.5 cm, and psoriasis can present as patches. Thus, the lesions described fit this classification.
