What could cause a nasty rash on a patient's penis head since two months that does not seem to be going away?

Hello,

Welcome back to icliniq.com.

I read your query and can understand your concern.I checked the picture (attachments removed to protect the patient's identity). If there was unprotected sex, one needs to think of sexually transmitted infections such as the following:

1. TPHA; Treponema pallidum hemagglutination.

2. HPV (human papillomavirus) DNA (deoxyribose nucleic acid) PCR (polymerase chain reaction) test.

3. Herpes simplex virus (HSV) one and two IgG (immunoglobulin G).

4. Herpes simplex virus (HSV) one and two IgM, serum test.

5. Chlamydia Trichomonas IgG.

6. HIV (human immunodeficiency virus) one and two antibodies, screening test.

7. HbsAg (hepatitis B surface antigen)

8. Urine complete test.

If not, it can be a simple bacterial infection, you can use the antibacterial ointment for local application and the tablet Doxycycline (Vibramycin) 100mg twice a day for five days. If there is itching, you need to think of fungal infection, antifungal ointment for local application, and for itching, you can take the tablet Cetzine (Zyrtec) once a night. Consult your specialist doctor, discuss with them, and take the medicines with their consent. Make sure you wash your genitalia twice a day morning and night and use normal water, no cold/ hot water. don’t use heavy pH soap.

I hope I have answered your question. Let me know if I can assist you further.

Regards.
