Final answer:
Severe nodulocystic acne signifies a serious skin condition that requires attention from a dermatologist. It could result from hormonal changes or an underlying health issue, and treatment may involve prescription medications or advanced dermatological procedures.
Step-by-step explanation:
Severe nodulocystic acne on the arms/upper back can be indicative of a serious skin condition and is important to address with medical supervision. This form of acne is characterized by deeper and more inflamed lesions such as nodules and cysts that can cause serious scarring and other complications if not treated appropriately. The presence of nodulocystic acne can be a sign of hormonal imbalances that often present during puberty but can also occur in adulthood, or it could be associated with other underlying health conditions that require medical attention. It is essential to consult with a dermatologist to determine the appropriate treatment, which may include prescription medications and potentially procedures such as laser therapies or chemical peels.
While acne is commonly associated with bacteria like Propionibacterium acnes, it is also important to rule out other skin conditions such as cellulitis, erysipelas, or erythema nodosum, which might present with similar symptoms but are caused by different pathogens and require different treatments.
Given the potential for acne to affect one's self-esteem and contribute to depression, seeking professional medical advice is not only beneficial for the physical health of the skin but also for mental wellbeing.
