Acne vulgar: diagnóstico e manejo pelo médico de família e comunidade

Acne vulgaris is the most common skin disease worldwide. It affects 85-100% of the population at any point in life. Consequently, it is a frequent reason for primary care visits. It usually begins at puberty, reaching its peak between the age of 14-17 in girls, and 16-19 in boys, and it is more severe and prevalent in males. Although widely discussed, Acne vulgaris still requires constant updating. We conducted a survey of clinical guidelines, systematic reviews, and meta-analyses published over the past 15 years, concerning acne vulgaris and its treatment. Acne vulgaris is usually divided in three clinical types: comedonal, papulopustular, and nodular. The diagnosis is based on clinical signs; however, other conditions should be considered. There are several pharmacological therapies available, especially retinoids, antimicrobials, and hormone therapy, which should be used after considering its indications (type of acne and its severity) and side effects. Thus, the family physician plays a leading role in addressing acne vulgaris, from diagnosis to management of therapeutic options.
