My Brother's Skin Condition: Insights on White Spots and Variants

Could you please provide more details about my brother's condition?

Dr.
Jiang: Hello, my younger brother is nine years old and is somewhat of a chubby meat-lover.
He was born prematurely and has been diagnosed with G6PD deficiency (favism).
Around the age of six, we noticed white patches of varying shapes and sizes all over his body (except for his face), which became more pronounced after physical activity.
These patches have continued to grow, with the largest area measuring about 3x6 square centimeters, and the patches are not very smooth.
However, unlike other reports, when he was around seven, some of the white patches developed small red spots, which have since disappeared; later, some of the white patches turned pink.
Surrounding some of the white patches is a darker ring, resembling a black outline around the white, and all the patches are different and non-itchy.
Initially, when we discovered this, we took him to see a doctor who said it was just ordinary tinea versicolor and recommended a vitamin supplement, suggesting it would improve in winter.
Since he turned seven, the condition has worsened, and we have sought multiple medical opinions, but the diagnoses have varied.
Just last year, a doctor took some skin tissue samples for examination and told my mother that the situation is not too severe at the moment, but there is a possibility of "mutation," so further blood tests are needed.
Could these pink-tinged white patches be considered a form of vitiligo? Is there a possibility of "mutation"? If it is not vitiligo, what treatment options are available, and what impact could this have on his health? I look forward to your response and greatly appreciate your help.

Based on your description, vitiligo is the most likely diagnosis.
Vitiligo is a chronic skin condition that generally does not have significant health implications.
However, it is advisable to take him to a dermatology department at a teaching hospital for evaluation and treatment.
Wishing you well.

More Info

Based on the information provided about your brother's skin condition, it appears that he may be experiencing a form of skin disorder characterized by white spots, which could potentially be vitiligo or another related condition. Vitiligo is a chronic skin condition that results in the loss of skin pigment, leading to white patches on the skin. The presence of red or pink spots alongside the white patches may indicate an inflammatory component or a secondary skin condition that warrants further investigation.

Given that your brother has a history of G6PD deficiency, it is essential to approach his skin condition with caution. G6PD deficiency can lead to increased sensitivity to certain medications and environmental factors, which could complicate his treatment options. The fact that the white patches have been increasing in size and number, and that they have changed in color, suggests that a thorough dermatological evaluation is necessary.

The description of the white patches being irregular in shape and size, along with the presence of a darker border, could indicate a few possibilities. While vitiligo is a common diagnosis for such symptoms, other conditions like tinea versicolor (a fungal infection that can cause lighter or darker patches on the skin) or even post-inflammatory hypopigmentation could also be considered. The transient nature of the pink spots that appeared and then disappeared might suggest an inflammatory response, possibly due to irritation or an allergic reaction.

It is crucial to follow up with a dermatologist, especially one affiliated with a teaching hospital, as they can provide a more comprehensive evaluation and possibly conduct further tests, such as a skin biopsy or blood tests, to rule out other conditions. The mention of "variants" could imply that there is a concern for a more complex or atypical presentation of a skin disorder, which may require specialized treatment.

In terms of treatment, if it is confirmed to be vitiligo, options may include topical corticosteroids, calcineurin inhibitors, or phototherapy. However, the choice of treatment should be tailored to your brother's specific condition, age, and overall health, particularly considering his G6PD deficiency. It is also important to manage expectations, as treatment for vitiligo can be a slow process, and results may vary from person to person.

As for the potential impact on his health, vitiligo itself is not harmful and does not typically affect overall health. However, it can have psychological effects, particularly in children, due to social stigma or self-image issues. Therefore, it may be beneficial to provide emotional support and consider counseling if needed.

In summary, your brother's condition warrants a thorough evaluation by a dermatologist to determine the exact nature of the white spots and to establish an appropriate treatment plan. It is essential to monitor any changes in his skin and to communicate openly with healthcare providers about any concerns or questions you may have.
