A nurse in a provider's office is collecting data from a client who reports pruritus and reddened, fluid-filled vesicles on her lower leg. The nurse should suspect which of the following disorders?

A. Seborrheic dermatitis primarily affects areas rich in sebaceous glands, such as the scalp, face, and upper trunk. Lesions are usually greasy, yellowish scales rather than pruritic, fluid-filled vesicles localized to the lower leg. B. Folliculitis is an infection of the hair follicles, presenting as small, red pustules or papules centered on hair follicles. It does not typically produce widespread fluid-filled vesicles and intense pruritus like contact dermatitis. C. Contact dermatitis is an inflammatory skin reaction caused by direct contact with an irritant or allergen. Typical findings include pruritus, erythema, and fluid-filled vesicles. The lower leg is a common site if the area came into contact with an irritant, such as plants, chemicals, or topical products. This pattern of localized vesicular rash and itching is characteristic of contact dermatitis. D. Cellulitis is a bacterial infection of the dermis and subcutaneous tissue, presenting as diffuse, red, warm, swollen, and tender areas, often with systemic symptoms such as fever. Vesicles are not a typical feature, and pruritus is generally mild or absent.
