AbstractTruncal acne is frequently overlooked in dermatological practice, even though it may result in scars and impact on self‐esteem and body image. Therefore, it is important to identify the disease early in order to initiate treatment in time and, thus, to prevent it from worsening and resulting in physical and psychological sequelae. The aim of this review is to provide an overview of what is currently known about truncal acne, its prevalence, aetiology and physiopathology, how its severity is currently evaluated, how to differentiate it from other skin afflictions and current treatment options. A review of literature considering the issue of truncal acne published up to 2019 and available from PubMed was conducted, and in total, 76 articles were selected from PubMed. Currently, only little information about truncal acne is available. Considered as having the same pathophysiology as facial acne, the clinical picture and treatment response seem to differ. Specific acne severity grading systems and quality of life questionnaires as well as a specific treatment algorithm are still lacking. Filling this gap should allow clinicians to assess truncal acne in the best possible way, choosing suitable treatment options, helping patients to improve treatment adherence and quality of life and finally allowing a better management of truncal acne. In conclusion, more knowledge is required to treat more efficiently truncal acne.
