A patient with acne vulgaris has inflamed, tender, and pus-filled lesions on their face. Which term best describes these lesions?

Explanation: The small, white bumps on the patient's forehead and chin are characteristic of closed comedones, also known as whiteheads. Comedones are non-inflammatory lesions and are one of the primary clinical manifestations of acne vulgaris.

Incorrect choices: a. Papules - Papules are small, red, inflamed bumps that may be present in acne vulgaris. However, they are not associated with the small, white bumps described in this question.

b. Pustules - Pustules are pus-filled lesions seen in acne vulgaris, but they are not the correct term for the small, white bumps in this scenario.

d. Nodules - Nodules are large, painful, solid lesions that extend deeper into the skin. They are not the correct term for the white bumps described in the question.

While some medications for acne (like retinoids) can increase sensitivity to the sun, and sun exposure can worsen acne or lead to hyperpigmentation, this is a beneficial recommendation.

Incorrect choices:

a. Squeezing and popping acne lesions to release pus. - This intervention can lead to infection and scarring, as well as exacerbate inflammation and further spread bacteria.

b. Recommending the use of abrasive facial scrubs daily. - Daily use of abrasive facial scrubs can irritate the skin and worsen acne symptoms. Gentle cleansing is preferred for individuals with acne-prone skin.

d. Applying over-the-counter hydrocortisone cream to the affected areas. - Hydrocortisone cream is a topical steroid and is not recommended for routine use on acne lesions. It may cause skin thinning and other side effects if used improperly.
