> Recurring, painful lumps in the armpit or groin are often dismissed in teenagers as "normal puberty skin." What the new European guideline (2026) says about HS in young people, why diagnosis in this age group is often delayed, and what parents can actually do.

## 60-second summary

- HS can start during adolescence, almost always after puberty begins.
- In young people, HS is often recognised later than in adults — not because it's rarer, but because it looks like ordinary puberty skin.
- A family history of HS raises the likelihood but is neither necessary nor proof on its own.
- This article does not diagnose or score anything — recurring lesions are a reason for a medical examination, never a verdict a website can issue.

**What this means:** If a teenager has repeated, painful lumps or abscesses in the armpit, groin or buttock area, a medical assessment is worthwhile regardless of age.

**What we are less certain about:** How often HS actually occurs in teenagers, and how much diagnosis is typically delayed, isn't settled — studies report very different figures.

**What you can do next:** The site's own teen and parent guide offers separate, age-appropriate paths onward, without deciding who should read it first.

## Article

A teenager keeps getting painful lumps in the armpit or groin. The first thought is almost always: puberty, maybe a stubborn pimple or an ingrown hair. That's a reasonable first guess — and most of the time, it's the right one. But when the same thing keeps happening in the same places, a second question is worth asking: could this already be HS (hidradenitis suppurativa, acne inversa)?

The answer is yes, and the new European S2k guideline for HS/acne inversa (Part 1, 2026) devotes a dedicated section to children and adolescents for the first time — a clear signal that this age group has long received too little attention in research and in care.

This article works through what that means: why diagnosis in young people is often delayed, what pattern matters more than a single lesion, and what family history actually does and doesn't tell you. It's written for parents and carers looking for an initial orientation before booking an appointment.

## Key takeaways

- HS can start during adolescence, almost always after puberty begins.
- In this age group, HS is often recognised later than in adults — not because it's rarer, but because it's more easily mistaken for something else.
- A family history of HS raises the likelihood but is neither necessary nor proof on its own.
- What matters is a recurring pattern at the same body sites, not a single lesion.
- This article does not replace a medical examination and does not make a diagnosis.

## Why diagnosis in teenagers often comes later

The new guideline describes HS in young people as possibly not rarer than previously assumed — just less often recognised in time. Several factors contribute:

**Milder or more atypical early presentations.** In its early stages, HS in teenagers sometimes shows up with less typical lesions or in less expected locations, making it harder to tell apart from ordinary teenage acne or ingrown hairs.

**The classic recurrence criterion isn't met yet.** Diagnostic criteria for HS rely partly on a recurring pattern over a certain period. In a condition that is still relatively new for that person, this pattern may simply not have shown itself as clearly yet in a teenager as it would in an adult with years of history.

**Delayed referral between specialties.** Pediatric and general practices see HS in adolescence less often than dermatology does, which can mean recurring symptoms get filed under something else at first, before a dermatology assessment happens.

None of this is a criticism of anyone — not of a parent who first assumed ordinary puberty skin, and not of a first practice that reached a different conclusion. It simply explains why this age group deserves particular attention in care.

## The pattern that matters more than a single lesion

A single painful lump or abscess is common and usually harmless — that's as true for teenagers as it is for adults. What more reasonably justifies a medical assessment is a **recurring pattern**: several episodes over a longer period, at the same or similar body sites, that keep coming back on their own rather than happening once and healing for good.

This is deliberately not a checklist for self-diagnosis. It's an orientation for when "that was probably just a pimple" should become "we should get this looked at":

- repeated painful lumps or abscesses at the same sites;
- symptoms that heal and then recur in a similar spot;
- more than one affected body area, even if not at the same time.

This description does not diagnose anything and does not replace an examination — it's a reason for a conversation with a clinician, nothing more and nothing less.

## Where this commonly shows up

As in adults, HS in teenagers typically affects body areas with sweat and oil glands in skin folds: armpits, groin, buttocks, and — less often at first — under the breasts. The exact location varies from person to person, and its presence alone proves nothing — similar symptoms can have other, usually more benign, causes.

## Why family history matters — and what it doesn't mean

HS has a hereditary component, and earlier disease onset is more often linked in research to a family history of the condition. In practice, that means:

- If a parent or sibling has HS, the statistical likelihood is higher for a teenager with similar symptoms.
- A family history is neither necessary nor sufficient: many people with HS have no known affected relatives, and most relatives of someone with HS never develop it themselves.
- A known family history can be an additional reason to take recurring symptoms in a teenager seriously sooner — but it is not a substitute for an examination, nor a requirement for seeking one.

## What this does not mean

Worth stating plainly, because this is where most unnecessary worry starts:

- A single painful lump does not automatically mean HS.
- Ordinary teenage acne, ingrown hairs, and other common, usually harmless skin changes remain the more likely explanations for a one-off episode in a teenager.
- Not having a family history does not rule out HS — any more than having one proves it.
- This article cannot and does not decide any of this for you.

## What you can actually do

If the pattern described above applies, the reasonable next step is a medical appointment — with a pediatrician, a GP, or dermatology directly, whichever is more accessible in your situation. Before the appointment, it helps to note when symptoms started, how often they recurred, and at which sites — that's more useful in the conversation than trying to remember everything afterward.

How to raise this with your child or teenager, how to prepare a medical appointment for this age group, and how school and daily life fit into it are covered in detail on the site's own [teen and parent guide](/en/hs-for-teens/) — with separate paths for teenagers and for parents, without this article deciding which one applies to you.

## What the evidence does not show

Current evidence does not show that:

- every recurring skin finding in a teenager is HS;
- there is a specific minimum age below which HS can be ruled out;
- a family history alone establishes or rules out a diagnosis;
- the gap between first symptoms and diagnosis is the same for everyone or in every healthcare system.

## The bottom line

HS in teenagers is real, and it is often recognised later in this age group than in adults — not because it's rarer, but because it's more easily mistaken for ordinary puberty skin. A recurring pattern at the same body sites is what justifies a medical assessment, not a single lesion and not family history alone. The most useful next step is rarely more research online — it's an appointment.

## FAQ

### At what age can HS start at the earliest?

HS almost always starts after puberty begins; onset in childhood before puberty is considered unusual. There isn't one single age that applies to everyone, since studies use different populations and definitions. What matters is not a specific age but a recurring pattern of symptoms.

### Is HS rare in teenagers?

It doesn't appear to be fundamentally rarer than assumed — it tends to be recognised later in this age group instead. Milder early presentations, atypical locations, or simply not yet meeting the classic recurrence criterion can all delay diagnosis compared with an adult who has had the condition for years.

### Does a family history of HS mean my child will definitely get it?

No. HS in a parent or sibling raises the statistical likelihood but is neither necessary nor sufficient for a person to develop it themselves. Many people with HS have no known family history, and most relatives of someone with HS never develop it themselves.

### Should I see a pediatrician, a GP, or go straight to dermatology?

Any of these can be a reasonable starting point. A pediatrician or GP can make an initial assessment and refer to dermatology if needed; for a clear, recurring pattern, going straight to dermatology can also make sense. What matters more than the exact entry point is that recurring symptoms actually get looked at by a clinician.

### Can this website tell me whether my child has HS?

No. This article explains patterns from research and the current guideline — it does not diagnose, count lesions, or assess photographs. Several skin conditions can look similar in teenagers, and only a medical examination can reliably tell them apart.

### What if my teenager doesn't want to talk about it yet?

That's a legitimate reaction, especially for symptoms in intimate areas. Disclosure should stay optional wherever that's reasonable. The site's own teen guide addresses exactly this, including specific wording for raising the topic without having to explain everything at once.
