The nurse is caring for a young adult who reports uncontrolled acne vulgaris. Which pathological findings should the nurse observe on inspection of skin areas commonly affected in acne vulgaris?

Acne vulgaris is a common skin condition characterized by various types of lesions, including comedones, papules, and pustules, primarily affecting areas with a high density of sebaceous glands, such as the face, neck, chest, and upper back. Here's why option C is the correct choice: A) Small, skin-colored, pedunculated papules in areas of skin folds and on other areas as skin tags: This description is more characteristic of acrochordons or skin tags, which are benign skin growths commonly found in areas of friction or skin folds. Skin tags are not typically associated with acne vulgaris. B) Hyperpigmented areas that vary in form and color and are slightly elevated from the skin: This description suggests post-inflammatory hyperpigmentation, which can occur after resolution of inflammatory lesions in acne vulgaris. However, it does not capture the primary pathological findings observed in active acne lesions. C) Hyperactive sebaceous areas forming comedones, papules, pustules on the face, neck, and upper back: Correct. Acne vulgaris is characterized by the formation of various lesions, including comedones (open and closed), papules, and pustules, resulting from the obstruction of hair follicles and overactivity of sebaceous glands. These lesions typically appear on areas with a high density of sebaceous glands, such as the face, neck, chest, and upper back. D) Sharply demarcated silvery scaling plaques with underlying redness on the elbows and knees: This description is more indicative of psoriasis, a chronic autoimmune skin condition characterized by sharply demarcated, raised, silvery scaling plaques commonly affecting extensor surfaces such as the elbows and knees. Psoriasis lesions are distinct from those seen in acne vulgaris.
