Eczema vs. Psoriasis: Which Specialist to Consult? - Dermatology

Rheumatology and Immunology


Eczema is not the same as psoriasis; they are distinct skin conditions.
If you are experiencing red rashes on the front of your lower legs and itchy, flaky rashes on the lower edge of your chest, it is important to seek appropriate medical care.
Given that you are also experiencing pain in your heels and back, and considering the comments from a doctor at Chang Gung Memorial Hospital suggesting that these symptoms may be related to psoriasis as a systemic condition, it would be advisable to consult a rheumatologist.
However, if the rheumatologist recommends seeing a dermatologist, it may be necessary to follow their guidance.
It can be beneficial to seek a second opinion from another dermatologist or rheumatologist if your current treatment is not effective.

Hello: Eczema is a type of dermatitis, and it is important to rule out infections caused by bacteria or fungi.
Psoriasis, commonly known as "plaque psoriasis," is a skin condition caused by an imbalance in the immune system.
The two conditions are completely different, with distinct clinical symptoms.
It is recommended to consult a dermatologist, as both diseases fall under the specialty of dermatology.
Based on the symptoms you described, they do not align with the typical symptoms and distribution of psoriasis, and your pain may not necessarily be related to the rash.
If your symptoms do not improve after treatment at a general clinic, it is advisable to visit a dermatology department at a regional hospital or higher, where a skin biopsy can be arranged to confirm the diagnosis.

More Info


Eczema and psoriasis are two distinct skin conditions, often confused due to their overlapping symptoms, such as redness, itching, and scaling. However, they have different underlying causes and treatment approaches. Eczema, also known as atopic dermatitis, is primarily associated with allergic reactions and is often triggered by environmental factors, irritants, or allergens. It typically presents as dry, itchy patches of skin that can become inflamed and may ooze or crust over. On the other hand, psoriasis is an autoimmune condition characterized by the rapid growth of skin cells, leading to thick, red patches covered with silvery scales. It can also affect the joints, leading to psoriatic arthritis.

Given your symptoms of red, itchy rashes on your lower legs and chest, along with scaling and pain in other areas, it is crucial to consult the right specialist for an accurate diagnosis and appropriate treatment. While some doctors may suggest seeing a rheumatologist for potential psoriatic arthritis, it is essential first to have a definitive diagnosis of your skin condition. A dermatologist is the most appropriate specialist to evaluate your skin issues, as they have the expertise to differentiate between eczema and psoriasis and can provide targeted treatment options.

If you have already seen a dermatologist and your condition has not improved, consider seeking a second opinion from another dermatologist. Sometimes, skin conditions can be resistant to standard treatments, and a fresh perspective may lead to a more effective treatment plan. Additionally, if there is a suspicion of an autoimmune component, the dermatologist may collaborate with a rheumatologist to address any systemic issues.

Regarding your concerns about treatment, it is essential to follow a comprehensive skincare regimen. For eczema, keeping the skin moisturized is crucial. Use fragrance-free moisturizers and avoid harsh soaps or irritants that can exacerbate the condition. If your symptoms are severe, topical corticosteroids may be prescribed to reduce inflammation and itching. For psoriasis, treatment options may include topical treatments, phototherapy, or systemic medications, depending on the severity of the condition.

In summary, while eczema and psoriasis share some similarities, they are distinct conditions requiring different approaches to treatment. It is advisable to consult a dermatologist for a thorough evaluation and to explore all possible treatment options. If necessary, they can refer you to a rheumatologist if there are concerns about joint involvement or other systemic issues. Remember, managing skin conditions often requires patience and persistence, as finding the right treatment can take time.
