Hello doctor,

It has been four months since I have been suffering this problem. I have been to the sexual clinic. They say that all my tests were negative. They keep saying it is a non-sexual rash. I have had this white spot near my urethral opening for three months which is what is worrying me. What is it? On the corona, I also have this rash which seems to be spreading around the penis head. What is it? I have attached the images. All the STD and HIV tests were negative.



Welcome to

The spots near the tip are a normal variation perhaps due to the keratinized mucous membrane near the tip as it is exposed and therefore it has a slightly rough texture. They are not warts.

I am more concerned about the rash on the corona of the glans. It looks like eroded skin along the circumference of glans.

I would like to rule out the possibilities of either candida or yeast infection or STDs (sexually transmitted diseases) like genital herpes.

Do you have any associated symptoms of pain, burning, or itching? Are you sexually active?

When was your last sexual contact? Was it protected or unprotected?

Thank you doctor,

I had received unprotected oral sex nine months ago. I have had a herpes simplex 1 and 2 tests and both were negative a year ago. I have had 11 broad tests for all STD and HIV and all were negative. I have been looking online and the only thing that looks close to this is lichen planus. Does it look like cancer? What else can it be? It has been there for six months or more. It was there in one area and now it has spread around the corona. Please help. Have you ever seen anything like that? If it is herpes, can it last for more then six months?



Welcome back to

Yes, this could be erosive lichen planus. It is usually a painful and tender condition.

Do you have any associated symptoms of pain, itching, or burning?

Is the oral mucous membrane involved with similar erosive lesions? Are there any skin lesions elsewhere?

Another possibility is that it could be Zoon 's balanitis (plasma cell balanitis) but that is not much symptomatic though there may be a slight burning sensation.

Hi since the last messege it seems like the rash has spread a little. I have been trying to keep it clean as possible but now I'm worried. I have had all STD tests all negative. what can this be? have u ever seen anything like It? what could be causing It? what's the treatment?

I have attached as many photos that may help better to see the problem

I have been to a urologist and they have checked and said it's normal and they also to further check for any infections did a cytopccy and the results were all clean. did a full broad 11 std test all came back negative and done it in the local hospital and through sending bloods and urine to a private company. I am highly confused.

is this HPV?
Does it look like herpes?
it's now been there for 7 months.

Does it look sexually transmitted to You? or does it look like something else you know or have seen. It seems like the skin has sunk or just lost it's thickness.

it's now spreading.
# Thank you. I have viewed the images.

I can see an annular lesion on glans. It is certainly more clearly visible then previously. It is not an STD for sure.
I will keep a possibility of granuloma annulare. It is a rare condition. Another possibility is of course annular Lichen planus but it is usually itchy and there is associated violaceous hue/pigmentation.

Is there any itching?

Hi there is no itching at all. . what causes this?
# Granuloma annulare is mostly idiopathic - no identifiable cause. Though it has an association with diabetes millions.

Ideally I would like to biopsy and confirm my clinical diagnosis

But this is a tricky site to convince someone for a biopsy for a non serious condition

Granuloma annulare may regress on its own

You may try a topical steroid e.g mometasone furoate 0.1 % ointment or triamcinolone acetonide 0.1 % ointment, twice daily.

Another option is topical tacrolimus 0.1% ointment. It is a non steroidal alternative
So will it ever go away? will my skin always stay the same?
# It would definitely respond to the topical remedies that I have suggested.
So where the skin has thinned away or eaten away will that ever come back? can you also tell me what causes this?

Tacrolimus 0.1% is it prescription based or?
# Tacrolimus is prescription drug. About 50% regress spontaneously within 2 years though GA lesions may persist for weeks to decades. Some may recur at the same site. In GA the surface markings of epidermis are attenuated due to epidermal thinning. It may reverse to an extent.
So it may not go back to normal?

How do I get tacrolimus 0.1%

I have hydrocortisone acetate 1%

How long do i use the cream for

And how often
# It would definitely improve on treatment and may resolve with some residual changes (50% regress within 2 years).

Tacrolimus is only available on prescription. I suggest you to kindly talk to your local practitioner for a prescription of the same.

Hydrocortisone 1% cream is a very mild topical steroid but you can certainly try it for the time being till you can either find a moderately potent topical steroid cream e.g mometasone furoate or triamcinolone acetonide or a topical calcineurin inhibitor e.g tacrolimus ointment.

The topical preparations can be used at least twice daily for 4-6 weeks and then followed up
Will that duration of time not damage the skin further or make the skin thin?

Hi sorry to bother you. I was prescribed
fusidic acid 2 cream is that any good

I'm just so confused on what to do. this is destroying my life.

Is fusidic acid 2 cream any good for this
# Fusidic acid 2 %cream has no role

It is an antibiotic
Ok so no good

That's what my doc gave me
# GA is not a bacterial infection. So fusidic acid cream has no role

Is he a dermatologist?

I will have to wait 6 weeks to see a derm

Is this definitely GA
# Start with hydrocortisone cream till you get an appointment
I been putting that twice a dsy
# Yes looks like GA. Biopsy would be confirmatory

How long have you been using hydrocortisone?
How would u get ga

Since yesterday
# It is idiopathic. No known cause

Genital GA is very rare
So u don't get it from STDS

It's rare that's what's scaring me
# Less likely possibility is of lichen planus but that is usually itchy and has a violet hue.
Not itchy at all
# Treatment for GA and lichen planus is almost the same

GA is not an STD
I have a few white spots under the glans skin

Is that apart of ga

Can this be transmitted if I was to have sex

Would my partner get it

If I have sex with it

# GA is not an STD

Rest of your glans looks pretty normal
