The condition in question is nodular and cystic acne on the back, which is medically referred to as Acne Vulgaris.. Clinical photograph sourced from Wikimedia Commons (CC BY-SA 4.0). Attribution: Sedef94.
Presents with open and closed comedones, inflammatory papules, pustules, and in severe cases, nodules and cysts. Lesions predominantly affect the face, chest, and upper back. Post-inflammatory hyperpigmentation and scarring may develop.
Onset typically in adolescence with hormonal changes. May be exacerbated by stress, certain medications (corticosteroids, lithium, androgens), occlusive cosmetics, and dietary factors. Family history of severe acne is a risk factor.
Mild: topical retinoids + benzoyl peroxide. Moderate: add topical/oral antibiotics. Severe/nodulocystic: oral isotretinoin. Hormonal: spironolactone or combined OCPs in females. Adjuncts: chemical peels, phototherapy.
