What could be the bump on the shaft with mild burning?

Hello,

Welcome to icliniq.com.

I read your query and gone through the attached images (attachment removed to protect patient identity).

After careful inspection of the attached image and considering relevant history, including unprotected sexual intercourse, duration of exposure around two weeks, elevated bump, and skin feeling, there is a possibility that the lesion is related to sexually transmitted infection.

The first possibility is the syphilitic chancre, as it is a painless and slight elevation of the skin. The point against the diagnosis of syphilis is a short time (often it takes weeks to manifest) and absence of ulceration. However, it is possible that ulcer formation could be under process.

The second possibility is a yeast infection, although the absence of itching and moist surface almost rules out the case.

The third possibility is that the lesion is unrelated to your sexual encounters, and it is a simple lesion related to skin disorders or superficial tissue infections. Before we can test for various sexually transmitted diseases, I feel this is the provisional cause for this lesion.

I hope this helps.

Hello,

Welcome back to icliniq.com.

Thanks for the follow-up and new images of the affected area (attachment removed to protect patient identity).

The attached new images support the first and third possibility, which we discussed earlier and almost rules out yeast infection as a possibility.

The possibility of these lesions unrelated to your sexual life, meaning simple skin infection and inflammation, is high compared to syphilitic chancre.
