Answer to Question 1

ANS: C
Tinea capitis is characterized by lesions in the scalp configured of scaly, circumscribed patches or patchy, scaling areas of alopecia. Generally the lesions are asymptomatic but a severe, deep inflammatory reaction may occur that manifests as boggy, encrusted lesions (kerions). Impetigo contagiosa is depicted in the figure showing the vesicular lesion around the nares area that has become vesicular. The lesions rupture easily, leaving superficial, moist erosions that tend to spread peripherally in sharply marginated irregular outlines. The exudate dries to form heavy, honey-colored crusts. The figure depicting inflammation on the cheek is cellulitis. Inflammation of skin and subcutaneous tissues is characterized by intense redness, swelling, and firm infiltration. Cellulitis may progress to abscess formation. The figure depicting streaked blisters surrounding one large blister is characteristic of contact dermatitis from poison ivy contact.

Answer to Question 2

ANS: C
When seborrheic lesions are present, the treatment is directed at removing the crusts. Parents are taught the appropriate procedure to clean the scalp. Shampooing should be done daily with a mild soap or commercial baby shampoo; medicated shampoos are not necessary, but an antiseborrheic shampoo containing sulfur and salicylic acid may be used. Shampoo is applied to the scalp and allowed to remain on the scalp until the crusts soften. Then the scalp is thoroughly rinsed. A fine-tooth comb or a soft facial brush helps remove the loosened crusts from the strands of hair after shampooing.
