Genital Lumps and Bumps in Malaysia: Causes, Testing & Treatment
A new lump, growth or sore on the genitals is most often caused by HPV (genital warts), molluscum contagiosum, herpes (HSV) or - less commonly but importantly - a primary syphilis chancre. Many harmless skin findings such as Fordyce spots and pearly penile papules also get mistaken for an STI. A short in-clinic review distinguishes them and most are easily treated.
Noticed a new bump, growth or sore? Confidential same-day review is available.
Normal vs abnormal
Usually normal
- Fordyce spots - small pale-yellow oil glands on the shaft or vulva
- Pearly penile papules - tiny dome-shaped bumps around the corona
- Sebaceous cysts - soft mobile lumps under the skin, usually painless
- Folliculitis from shaving - single red bumps centred on a hair
Get it checked
- A single painless firm ulcer with a clean base (possible syphilis chancre)
- Soft cauliflower-like growths in clusters
- Pearly dome-shaped bumps with a tiny central dimple
- Painful grouped blisters that burst and crust
- Any new lump that bleeds, grows quickly or persists beyond 2 weeks
Common causes
Primary syphilis - a single painless ulcer that heals on its own without treatment. Primary syphilis (chancre)
A single painless firm ulcer with a clean indented base, appearing 10 - 90 days after exposure. Heals on its own - but the infection persists. Cured with a single in-clinic penicillin injection.
HPV warts - usually painless, treated in-clinic; partners benefit from HPV vaccination. Genital warts (HPV)
Soft, flesh-coloured cauliflower-like growths caused by low-risk HPV types. Treated in clinic with cryotherapy, electrocautery or topical therapy. Vaccination prevents recurrence.
Molluscum contagiosum - pearly papules with a central dimple; cleared in clinic. Molluscum contagiosum
Pearly dome-shaped papules with a tiny central dimple (umbilication), spread by skin-to-skin contact. Treated in clinic with cryotherapy, curettage or topical therapy.
Herpes - painful grouped blisters on a red base, controlled with antivirals. Herpes (HSV)
Painful clustered fluid-filled blisters that ulcerate then crust, often preceded by a tingling prodrome. Antivirals shorten outbreaks and suppress recurrence.
Normal anatomical variants
Fordyce spots, pearly penile papules, sebaceous cysts and folliculitis are common and harmless. A brief in-clinic review reassures you and avoids unnecessary worry.
When to see a doctor
Red flags
- Any new lump, ulcer or growth on the genitals, anus or mouth
- A painless ulcer that appeared and then healed by itself
- Bumps that bleed, grow quickly or persist beyond 2 weeks
- Painful clustered blisters or recurrent outbreaks at the same site
- Recent unprotected sexual contact, especially with a new partner
Recommended tests
- In-clinic visual examination - many causes are diagnosed clinically
- Syphilis serology (RPR + treponemal antibody); dark-field microscopy of a chancre when available
- HSV PCR swab of a fresh blister (highest yield within 48 hours)
- Full STI Essentials panel (HIV, syphilis, chlamydia, gonorrhoea, hepatitis B) - multiple STIs often co-exist
- Biopsy only if a lesion is atypical, ulcerated or fails to clear with first-line treatment
Treatment pathway
Treatment is targeted to the cause: a single penicillin injection cures early syphilis, cryotherapy or electrocautery clears most warts and molluscum, and antivirals control herpes outbreaks. Normal anatomical variants need no treatment beyond reassurance. Your personal health concierge coordinates the review, in-clinic procedure, partner support and follow-up in one confidential pathway.
Self-check
Quick self-check
- Is the lump or sore painless?
- Has it appeared since a recent unprotected sexual contact?
- Are there multiple bumps clustered together?
- Do you have painful blisters that come back to the same spot?
- Has a current or recent partner been diagnosed with any STI?
