Comedones (blackheads and whiteheads) - This choice is incorrect. Comedones are a hallmark clinical feature of acne vulgaris, and they occur when hair follicles become clogged with sebum and dead skin cells.
Papules and pustules - This choice is incorrect. Papules are small, red, inflamed bumps, while pustules are pus-filled lesions. Both are common manifestations of acne vulgaris.
The clinical manifestation described in option c (erythematous, raised plaques with silver scales) is not commonly seen in acne vulgaris. This description is characteristic of psoriasis, a chronic autoimmune skin condition. Acne vulgaris is characterized by the presence of comedones (blackheads and whiteheads), papules, pustules, nodules, and cysts on the skin, primarily affecting the face, neck, chest, and back.
Nodules and cysts - This choice is incorrect. Nodules and cysts are severe forms of acne vulgaris, characterized by larger, painful, and deeper lesions beneath the skin's surface. They are more likely to cause scarring and require medical intervention.
