Is it possible for a dermatologist to misdiagnose genital eczema as herpes?


Hello Dr.
Hsu, I read the article you previously answered.
Is it very painful when herpes first turns into blisters? If it only itches and is not painful, could it still be herpes? Additionally, I would like to ask you about my situation.
I have had two to three recurrences that occurred after burning joss paper.
After burning the joss paper in the morning, I might develop small red spots that start to itch in the afternoon or evening, possibly more than half an hour later.
I have seen four doctors, two of whom were at a sexually transmitted disease prevention center, and they said it was eczema, while a dermatologist said it was herpes.
This has been troubling me for a long time.
I also saw you mentioned that blood tests show almost 80% positive results.
What methods are available to confirm the diagnosis? This situation has been ongoing for three years, with an average of two recurrences per year.
In the past three years, I have been in two relationships without any signs of eczema or herpes.
Is there a method to confirm 100% whether it is eczema or herpes? Currently, the diagnosis is based on visual inspection.
Thank you very much, and I look forward to your response.
Wishing you peace and well-being.

Ah Xun: Hello, herpes during the blister stage may not be particularly painful.
Whether it is herpes can be diagnosed through medical consultation.
Sometimes, it can be difficult to distinguish between herpes and eczema.
There is no need to be overly concerned, as both conditions can heal on their own.
Therefore, it is not necessary to differentiate them 100%.
If there are any unclear points, feel free to ask again, and we can discuss and research further.
Answers found online should only be used as a reference; if necessary, it is still important to seek medical care at a healthcare facility.

More Info


Eczema and herpes can indeed be misdiagnosed due to overlapping symptoms, particularly during the initial stages of herpes infection. Herpes typically presents with painful blisters or sores, while eczema is characterized by itching, redness, and inflammation of the skin. However, in some cases, especially when herpes lesions are in the blistering phase, they may not be painful but rather itchy, leading to confusion in diagnosis.

When it comes to your specific situation, it’s important to consider the context of your symptoms. If you are experiencing small red spots that begin to itch after certain activities, such as burning incense or paper, it could suggest a contact dermatitis or an allergic reaction rather than herpes. Eczema can flare up due to various triggers, including environmental factors, stress, and irritants. The fact that you have seen multiple doctors and received different diagnoses indicates the complexity of skin conditions and the need for thorough evaluation.

To differentiate between eczema and herpes, a healthcare provider may perform a physical examination and consider your medical history, including any previous outbreaks and potential triggers. In some cases, laboratory tests such as viral cultures or polymerase chain reaction (PCR) tests can be conducted to confirm the presence of the herpes virus. Blood tests for herpes antibodies can also provide information, but they are not definitive for diagnosing active infections.

Given your history of recurrent symptoms, it may be beneficial to keep a detailed diary of your outbreaks, noting any potential triggers, the duration of symptoms, and the treatments you have tried. This information can help your healthcare provider make a more accurate diagnosis.
In terms of management, if your condition is indeed eczema, treatment typically involves the use of topical corticosteroids to reduce inflammation and itching, as well as moisturizers to maintain skin hydration. If herpes is confirmed, antiviral medications may be prescribed to manage outbreaks and reduce the frequency of recurrences.

To prevent future flare-ups, whether from eczema or herpes, consider the following strategies:
1. Identify Triggers: Keep track of activities, foods, or environmental factors that precede your symptoms. This can help you avoid potential triggers in the future.

2. Skin Care Routine: Maintain a consistent skincare routine that includes gentle cleansing and regular moisturizing. Avoid harsh soaps and hot water, which can exacerbate eczema.

3. Stress Management: Stress can be a significant trigger for both eczema and herpes outbreaks. Incorporating stress-reducing techniques such as mindfulness, yoga, or regular exercise can be beneficial.

4. Consult a Dermatologist: If your symptoms persist or worsen, consider seeking a referral to a dermatologist who specializes in skin conditions. They may offer more advanced diagnostic options and tailored treatment plans.

5. Educate Yourself: Understanding your condition can empower you to manage it better. Resources from reputable health organizations can provide valuable information about eczema and herpes.

In conclusion, while eczema and herpes can share similar symptoms, a thorough evaluation by a healthcare professional is essential for accurate diagnosis and effective treatment. Keeping track of your symptoms and potential triggers will aid in this process, and proactive management strategies can help minimize future flare-ups.
