Acne conglobatarare, very severe acne
Acne conglobata is a rare, very severe form of acne in which inflammations merge into large abscesses and deep inflammation under the skin. It mainly affects men. This form always needs intensive care from a dermatologist.
What does acne conglobata look like?
Where ordinary acne consists of separate pimples and blackheads, the inflammations in acne conglobata merge together. Large inflammations and abscesses develop, often on the face and trunk. Without treatment, scars often remain after healing.
Is acne conglobata the same as acne vulgaris?
No. Acne vulgaris is the umbrella term for ordinary acne caused by blocked sebaceous glands, from mild to severe. Acne conglobata is a rare, very severe form within that spectrum, with its own presentation and its own treatment approach.
What is the difference with hidradenitis suppurativa?
Hidradenitis suppurativa causes deep, recurring inflammations in skin folds, such as the armpits and groin. Acne conglobata arises from the sebaceous glands and hair follicles and mainly affects the face and trunk. The conditions look similar and sometimes occur together. A doctor makes the distinction, and that matters because the treatment differs.
How is acne conglobata treated?
Always through a dermatologist. For severe acne a tablet treatment is usually started. Starting quickly is important to limit permanent damage. The dermatologist supervises the treatment closely and adjusts it where needed.
Limiting scars
With deep, long-lasting inflammation the risk of scarring is at its highest. The sooner the inflammation is under control, the smaller the chance that anything remains. So do not wait and see with this presentation.
Frequently asked questions about acne conglobata
What causes acne conglobata?
Like other acne it starts with blocked hair follicles and sebaceous glands, followed by inflammation. In acne conglobata that inflammation runs very severely and inflammations merge together. Why this happens to some people and not others is not always clear. It mainly affects men.
Is acne conglobata dangerous?
It is not a threat to your general health, but it is a severe skin condition that leaves scars without treatment and can have a big impact. Quick assessment and treatment are therefore important.
Does acne conglobata clear on its own?
Do not count on it. This form always needs treatment and intensive care from a dermatologist.
How is acne conglobata treated?
Usually with a tablet treatment through the dermatologist, combined with close supervision. The treatment plan is tailored to the severity and the risk of scarring.
What is the difference with cystic acne?
Both are severe, deep forms. Cystic acne involves separate deep bumps (cysts). In acne conglobata, inflammations merge into larger abscesses and tracts under the skin. The line is not always sharp, a dermatologist assesses the picture.
