Hi,
A circular red patch on the penis that is causing itchiness could be a symptom of several conditions. One possibility is a
fungal infection such as a jock itch, which is caused by the same type of fungus as an athlete's foot.
Another possibility is a sexually transmitted infection such as herpes or syphilis. It is important to note that not all sexually transmitted infections present with visible symptoms, so it is important to get tested regularly if you are sexually active. Other possible causes could include a
skin allergy or irritation, or a skin condition such as
psoriasis or eczema.
Meet a doctor for accurate diagnosis and treatment. They may perform a physical exam and possibly some tests to determine the underlying cause of the red patch. Treatment will depend on the underlying cause and may include antifungal or
antiviral medication, topical creams or
ointments, or other medications to manage symptoms. In the meantime, it is important to avoid scratching or rubbing the affected area to prevent further irritation and potential infection.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
