Yes â if four clinicians are disagreeing between molluscum contagiosum (MC) and genital warts (HPV), a biopsy of one representative lesion is a reasonable way to settle the diagnosis, especially before marriage.
What the description suggests
The 2 bumps with a central white dimple/umbilication are quite characteristic of molluscum contagiosum. Genital HPV warts more often appear as rough, papillary/cauliflower-like or irregular skin-colored growths, although some can be smooth and therefore overlap clinically.
The larger and other smooth skin-colored bumps could potentially be HPV, MC, or another benign lesion. HSV is less likely because herpes typically causes clusters of painful blisters that break down into ulcers, rather than persistent painless bumps with a central dimple.
So, from the description alone, MC sounds more plausible than HSV, but the other lesions cannot reliably be classified without examination.
Is biopsy the best confirmation?
When the clinical diagnosis is uncertain, histopathology of a lesion can distinguish MC from HPV and other lesions.
However, a biopsy is not routinely necessary when an experienced dermatologist can confidently diagnose a typical lesion. In your particular situation, because multiple specialists have given different opinions, biopsy is a reasonable option.
A dermatologist can usually remove/biopsy one representative lesion, rather than sampling all five.
Is it painful? Can biopsy spread the lesions?
Usually, the area is numbed with local anesthetic, so you should feel the initial injection but little or no pain during the procedure. There may be mild soreness afterward.
A properly performed biopsy does not normally cause the infection to spread throughout the body. With MC, however, manipulation of lesions can theoretically cause local spread through autoinoculation, so unnecessary handling/picking should be avoided. Your dermatologist can choose the safest method and may remove the lesion completely while obtaining the tissue.
What about HPV testing/genotyping?
If you're male and have external penile lesions, routine HPV testing is generally not recommended. There is no standard blood test that can tell whether a man has genital HPV, and HPV typing usually doesn't change management of an ordinary external wart.
If biopsy confirms HPV, your doctor can discuss whether any additional testing has a meaningful clinical benefit. Do not let the availability of an HPV genotype test make you feel that you need to identify your exact HPV strain.
Your
HIV/STI results
Your negative HIV ELISA, TPHA, HBsAg and HCV tests at 43 days are reassuring, but their interpretation depends on the exact assays and timing. Those results don't determine whether the penile bumps are MC or HPV.
Also, neither MC nor HPV means that someone has HIV.
Before marriage
Until the diagnosis is clarified:
Don't pick, squeeze, shave over, or scratch the lesions.
Avoid sexual contact involving the lesions until you've been assessed/treated.
Condoms reduce transmission of HPV but cannot completely prevent HPV or MC, because uncovered skin can still contact the partner.
If these are MC, they are curable/manageable, and the immune system often clears them.
If they are genital warts, the visible warts are treatable; HPV itself usually becomes undetectable/suppressed by the immune system over time.
My practical recommendation: because you have conflicting specialist opinions, I would accept the infectious-disease specialist's suggestion of dermatology review with biopsy of one representative lesion rather than continuing to seek multiple opinions. It can give you a much clearer answer before marriage.
I can't reliably judge whether the lesions are HPV or MC without actually seeing the attached image in this conversation. If you upload the clearest close-up photograph, I can explain which visual features favor MC, HPV, HSV, or benign penile lesionsâbut a photograph still cannot replace histopathology when clinicians disagree.
