Answer to Question 1

ANS: D
In cellulitis, a patient often describes a history of a break in the skin from an injury, insect bite or sting, or previous procedure preceding the onset of redness, swelling, and pain at the site. The affected area is tender, swollen, reddened, and warm. Streptococcus or staphylococcal commonly causes the infection. The lower leg is a common site, usually unilateral.

Answer to Question 2

ANS: B
Patients with autoimmune disease frequently experience isolated, multiple skin lesions that emerge as firm, tender, reddened nodules, usually along the anterior aspect of the leg, although other sites can be involved. Over a period of up to 2 weeks, the lesions fade in color and the degree of firmness decreases.
