Key facts
Male genital skin conditions at a glance.
The essentials, in plain English - what these conditions are, what causes them, and how they’re assessed in the UK today.
-
What it covers
A wide range of conditions affecting the penis, foreskin and scrotum - from harmless normal variants to premalignant disease.
-
Common causes
Infection, irritant contact, autoimmune skin disease, HPV and HSV, and - often overlooked - undiagnosed diabetes.
-
Normal variants
Fordyce spots and pearly penile papules are extremely common and need reassurance, not treatment.
-
Watch for phimosis
Lichen sclerosus can scar the foreskin tight over time - early treatment reduces this risk.
-
Premalignant disease
Penile intraepithelial neoplasia (PeIN) is HPV-associated and needs specialist urology surveillance.
-
Who to see
Dermatology, urology and GUM (sexual health) work together - many men need more than one specialist.
Why this guide matters
Most of this is common - and treatable.
Genital skin problems are among the most under-reported in medicine, often out of embarrassment. The three points below shape everything else on this page.
-
Normal variants are very common
Fordyce spots and pearly penile papules affect a large proportion of men and need reassurance, not treatment or worry.
-
Lichen sclerosus needs early treatment
Left untreated it can scar the foreskin and carries a small malignancy risk - ultrapotent steroids used early change the outlook.
-
Non-healing lesions get biopsied
Diagnostic uncertainty, or anything not healing, is never left unchecked - a biopsy settles it quickly and reliably.
How the diagnosis is made
From first symptoms to a clear diagnosis.
The steps a UK GP, dermatologist, urologist or GUM clinician will normally follow, in order - so you know what to expect and why.
Phase 1 · Assessing
History, examination and sexual health screening
Phase 2 · Confirming
Blood glucose and biopsy where needed
Phase 3 · Planning
Specialist referral and MDT care
- 01
Assessing
Focused history
Hygiene habits, sexual history, new products or soaps, and any history of diabetes or other skin conditions.
- 02
Assessing
Specialist examination
A careful look at the glans, foreskin and scrotum - most diagnoses in this area are made by inspection alone.
- 03
Assessing
STI screening
A GUM (sexual health) assessment when infection, warts or herpes are suspected, or sexual history warrants it.
- 04
Confirming
Blood glucose check
Recurrent or stubborn balanitis is a classic first sign of undiagnosed type 2 diabetes - worth ruling out.
- 05
Confirming
Biopsy when uncertain
For non-healing lesions, diagnostic doubt, or suspected PeIN or malignancy - a small skin sample settles the diagnosis.
- 06
Planning
Dermatology or urology referral
Lichen sclerosus, Zoon balanitis, PeIN and anything not settling with simple measures deserves specialist input.
- 07
Planning
MDT planning where needed
Complex or premalignant cases are best managed jointly across dermatology, urology and GUM.
Typical timeline: a first visit to a settled plan within a few weeks.
Symptoms
What to look and feel for.
Symptoms overlap a great deal across different conditions - which is exactly why a specialist examination matters more than guessing from a description.
-
Itching and soreness
The most common complaint across almost every condition on this page - from simple irritation to lichen sclerosus.
-
Discharge
Often points to infective balanitis - candida or bacterial - especially under the foreskin.
-
Skin changes
Whitening, thickening, redness or scaling - the pattern helps distinguish psoriasis, lichen sclerosus and lichen planus.
-
Tightening foreskin (phimosis)
A foreskin that has become difficult to retract - a hallmark of untreated lichen sclerosus.
-
Bumps or spots
Small, harmless-looking bumps can be Fordyce spots, pearly penile papules, or genital warts - appearance and pattern matter.
-
Ulceration - red flag
Any non-healing sore, ulcer or growth needs prompt specialist assessment to exclude PeIN or malignancy.
-
Scrotal changes
Sebaceous cysts, small red-purple spots (angiokeratomas) and eczema are common and usually benign.
-
Red flag - non-healing lesion
A patch, plaque or growth that does not heal in a few weeks warrants urgent dermatology or urology review.
Conditions this guide covers
A wide spectrum, one careful assessment.
From reassuring normal variants to conditions that need active, specialist-led treatment.
-
Balanitis
Inflammation of the glans - infective (candida or bacterial), irritant, or linked to undiagnosed diabetes. See our diabetes guide.
-
Lichen sclerosus
A chronic inflammatory skin condition (balanitis xerotica obliterans) carrying phimosis and malignancy risk if untreated.
-
Genital lichen planus
An inflammatory condition that can affect genital skin alongside other sites - itchy, purple-red patches.
-
Genital psoriasis
Common but often under-reported - genital skin needs gentler treatment than psoriasis elsewhere on the body.
-
Genital warts (HPV)
Caused by human papillomavirus - treated with cryotherapy, podophyllotoxin or imiquimod under GUM guidance.
-
Genital herpes (HSV)
A sexually transmitted infection causing painful blisters or ulcers - assessed and managed through sexual health services.
-
Fordyce spots
Visible sebaceous glands - a completely normal variant needing reassurance only, never treatment.
-
Pearly penile papules
Small benign bumps around the glans rim - another normal variant, not an infection.
-
Zoon balanitis
A chronic inflammatory condition seen almost exclusively in uncircumcised men - circumcision is often curative.
-
Penile intraepithelial neoplasia
A premalignant, HPV-associated condition needing specialist urology surveillance and active treatment.
-
Scrotal conditions
Sebaceous cysts, benign angiokeratomas, and scrotal eczema - each with a distinct, usually straightforward, management path.
Treatment
How these conditions are treated in the UK.
From simple hygiene advice to ultrapotent steroids, selective circumcision, and coordinated specialist surveillance.
-
Balanitis
Hygiene advice plus a topical antifungal or antibacterial as indicated. Persistent or recurrent cases need diabetes checked and treated.
-
Lichen sclerosus
Ultrapotent topical steroids are first-line and highly effective. Circumcision is considered selectively for scarring or recurrent phimosis.
-
Genital psoriasis
Mild topical steroids or calcineurin inhibitors - genital skin is thin and sensitive, so potency and duration are carefully judged by dermatology.
-
Genital warts
Cryotherapy, podophyllotoxin or imiquimod, guided by a GUM specialist depending on number, size and site of lesions.
-
Normal variants
Fordyce spots and pearly penile papules need reassurance only - they are not infectious, not harmful, and do not require treatment.
-
Penile intraepithelial neoplasia
Topical imiquimod or 5-fluorouracil, or surgical excision, under specialist commissioned urology surveillance given the premalignant risk.
-
Zoon balanitis
Circumcision is often curative in uncircumcised men with this chronic inflammatory condition, guided by specialist assessment.
-
STIs and MDT care
Confirmed infections are treated per GUM protocols, with joint dermatology, urology and GUM input for complex or overlapping presentations.
Selective circumcision is a recognised treatment for scarring lichen sclerosus and for Zoon balanitis. Read more in our male circumcision guide. Where a diagnosis is uncertain, a small skin biopsy gives a definitive answer.

Red flags
When it needs urgent attention.
Most genital skin symptoms are manageable in primary care. These are the situations that aren’t - and where urgent specialist input is needed.
-
Non-healing ulcer or growth
Any lesion that persists beyond a few weeks needs urgent specialist review to exclude penile intraepithelial neoplasia or malignancy.
-
Suspected PeIN
Persistent red or white patches, especially in HPV-positive men, need dermatology or urology biopsy and specialist surveillance.
-
Severe phimosis with pain
A foreskin that cannot be retracted and is causing pain or affecting urination needs prompt urology assessment.
-
Paraphimosis
A retracted foreskin that cannot be returned to its normal position and is swelling is a urological emergency - seek immediate care.
-
Signs of systemic infection
Spreading redness, fever or severe pain with balanitis may indicate cellulitis and needs same-day medical assessment.
-
Undiagnosed diabetes
Recurrent balanitis with no clear cause should prompt a blood glucose check - it is often the first sign of type 2 diabetes.
-
New ulcerating STI symptoms
Painful blisters or ulcers suggestive of herpes, or any new genital ulcer, need urgent GUM assessment and treatment.
-
Rapidly changing pigmented lesion
Any mole-like lesion that changes size, colour or shape on the genital skin should be assessed without delay.
Living with it
Manageable, and nothing to be embarrassed about.
Four things that make the biggest difference day to day - simple hygiene, understanding what’s normal, checking for diabetes when relevant, and not sitting on a lesion that lingers.
A quiet reminder
These conditions are common, and clinicians see them every day.
There is no need for embarrassment - a quick, matter-of-fact assessment usually brings real relief.
- 01 Hygiene
Simple, gentle care
Wash daily with water or a soap substitute, dry thoroughly, and avoid perfumed products that commonly trigger irritation.
- 02 Reassurance
Know what is normal
Fordyce spots and pearly penile papules are extremely common variants - they are not infections and cannot be passed on.
- 03 Diabetes
Ask about blood glucose
If balinitis keeps coming back, a simple blood test can rule out or confirm diabetes as the underlying driver.
- 04 Escalate
Do not ignore a lesion that lingers
Anything that does not heal, changes, or worries you deserves a specialist look rather than watchful waiting alone.
Frequently asked
Everything we get asked about this topic.
Quick answers on balanitis, normal variants, lichen sclerosus, cancer risk, warts and when to seek help.
-
What is balanitis and what causes it?
Balanitis is inflammation of the glans (head) of the penis. It can be infective - most often candida (thrush) or bacterial - or caused by irritant or contact dermatitis from soaps and products. Poor hygiene and undiagnosed diabetes are common contributing factors, so recurrent balanitis is often investigated with a blood glucose check.
-
Are Fordyce spots and pearly penile papules something to worry about?
No. Both are completely normal, benign variants of genital skin anatomy. Fordyce spots are visible sebaceous (oil) glands, and pearly penile papules are small bumps around the rim of the glans. Neither is infectious, neither is linked to poor hygiene, and neither needs treatment beyond reassurance.
-
Can lichen sclerosus affect the foreskin permanently?
Left untreated, lichen sclerosus (sometimes called balanitis xerotica obliterans) can cause progressive scarring and tightening of the foreskin, known as phimosis. Ultrapotent topical steroids used early are highly effective, and circumcision is considered selectively when scarring is significant.
-
Is there a cancer risk with genital skin conditions?
Most conditions covered here are benign, but a small number - particularly lichen sclerosus and HPV-related changes - carry an increased risk of penile intraepithelial neoplasia (PeIN) or, rarely, penile cancer. This is why non-healing lesions or persistent patches are always biopsied when there is diagnostic uncertainty.
-
How are genital warts treated?
Treatment depends on the number, size and location of warts, and is usually guided by a GUM (sexual health) specialist. Options include cryotherapy (freezing), topical podophyllotoxin, or topical imiquimod, which stimulates the immune system to clear the lesions over several weeks.
-
When should I see a specialist rather than wait?
See a specialist promptly for any ulcer or growth that does not heal within a few weeks, a foreskin that has become difficult to retract, discharge that persists after simple hygiene measures, or any lesion that is changing in appearance. Dermatology, urology and GUM services all see these conditions regularly.
