Truncal acne

A dermatological condition characterized by the presence of acne on the trunk of the body, including the chest, back, and shoulders. Truncal acne can lead to persistent scarring, such as macular atrophic scarring and keloids, and is often caused by hormonal changes, genetics, and lifestyle factors. This condition primarily affects adolescents and young adults, but can also occur in individuals of any age who are prone to acne.
