I have a rash on my penis. Is it contact dermatitis?

Question

Hello doctor,

I have a rash on the penis. A dermatologist suggested possible contact dermatitis, and I would like a second opinion from you.

I also have mild itching with no discharge or burning sensation. The rash involves the glans and extends circumferentially about halfway up the shaft.

Currently, I am using Triamcinolone cream, applied twice daily.

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern.

Thank you for sharing the photo along with the detailed history (the attachments were removed to protect the patient's identity).

Based on the image, the rash on the glans appears as diffuse redness with mild surface irritation and shine, without any discrete cauliflower-like growths, ulcers, pus, or discharge.

The involvement is circumferential around the glans and appears smooth rather than raised. You also report only mild itching, with no burning during urination and no discharge.

Taken together, these findings strongly support contact or irritant dermatitis rather than a sexually transmitted infection, psoriasis, fungal infection, warts, or malignancy. This is a very common condition that we encounter frequently.

Contact dermatitis of the glans commonly occurs due to exposure to irritants such as soaps, body washes, antiseptics, condoms, lubricants, or spermicides.

Excessive washing or scrubbing, repeated friction from masturbation or sexual activity, and prolonged moisture or sweating can also contribute to inflammation.

The skin of the glans is extremely delicate, and once irritated, redness and sensitivity may persist for several weeks even after the triggering factor has been removed.

Importantly, nothing in the image suggests cancer or a serious sexually transmitted disease. This appears to be an inflammatory and reversible condition; however, the key to recovery is gentle care and avoiding overtreatment.

Triamcinolone is a medium-potency steroid and should be used with caution on the glans. Short-term use can help calm inflammation, but prolonged use may thin the skin and delay healing.

If you have already been using it for more than seven to 10 days, it is better to stop and switch to a safer option, such as Methylprednisolone 0.1 percent cream (Advantan), applied once daily for seven days only.

For itching, you may take Cetirizine 10 milligrams at bedtime for a few days. During the day and afternoon, apply Vaseline (petroleum jelly) to the tip of the glans to help repair the damaged skin barrier and promote faster healing.

I hope this helps.

If you have any further questions, please feel free to ask.

Thank you.
