Persistent rashes can often be misunderstood as psoriasis, leading patients to seek treatments that may not be suitable for their actual condition. In many cases, self-diagnosis or information gathered from the internet can contribute to this confusion. This article aims to highlight the significance of obtaining a precise diagnosis from a qualified healthcare professional in order to initiate appropriate treatment. Associate Professor Premjit Juntongjin, M.D., emphasizes the importance of accurate diagnosis in managing skin conditions.
Example 1:
Scenario: Thick, itchy rashes on ankles
Myth A patient seeks treatment for what they believe is psoriasis due to thick rashes on their ankles. They’ve experienced intermittent itching in this area for a decade.
Truth After a thorough examination, a dermatologist identifies a reddish-brown rash with minimal scaling exclusively on the ankles. No other symptoms or signs of psoriasis, such as scalp involvement, nail abnormalities, or joint pain, are noticed. The dermatologist correctly diagnoses this as a chronic eczema.
With the appropriate treatment and proper skin care, the rash gets resolved with no more itchiness.
Example 2:
Scenario: Red Rashes on Limbs Since Childhood
Myth: A patient believes he has psoriasis due to red rashes distributed across his limbs, a condition he’s experienced since childhood.
Truth: A dermatologist conducts a physical examination and observes dry skin throughout the body. The red, scaly rash is most prominent in skin folds like the crook of the arms, knees, neck, and eyelids. The dermatologist also notes a history of morning runny nose. This leads to a diagnosis of atopic dermatitis.
With the appropriate treatment, including identifying triggering factors, lifestyle modification, and proper skincare, the rashes gradually improve.
Conclusion:
Accurate diagnosis is the cornerstone of effective treatment for skin conditions. Patients should refrain from self-diagnosis and rely on qualified healthcare professionals to identify their condition correctly.
