Insights
Hypopigmentary disorders are common in children. Pityriasis alba, vitiligo, leprosy, nevus depigmentosus, and tinea versicolor were the most frequent conditions identified in this pediatric dermatology study.
Area of Science:
- Pediatric Dermatology
- Dermatological Disorders
- Clinical Research
Background:
- Hypopigmentary disorders represent a common group of dermatoses observed in the pediatric population.
- Understanding the prevalence and characteristics of these conditions is crucial for effective management in children.
Purpose of the Study:
- To investigate the frequency and specific patterns of hypopigmentary disorders among children.
- To identify the most common causes of hypopigmentation in pediatric patients.
Main Methods:
- A descriptive clinical study was conducted over 23 months.
- Inclusion of 113 pediatric patients (61 boys, 52 girls) diagnosed with hypopigmentary disorders.
- Data collection focused on frequency, age of onset, and specific diagnoses.
Main Results:
- The overall frequency of hypopigmentary disorders was 3.28 per 1000 children in the dermatology outpatient department.
- The most common conditions were pityriasis alba (24.7%), vitiligo (20.4%), leprosy (11.5%), nevus depigmentosus (10.18%), and tinea versicolor (6.2%).
- Other diagnosed conditions included hypomelanosis of Ito, post-inflammatory hypopigmentation, and pityriasis rosea, among others.
Conclusions:
- Pityriasis alba, vitiligo, leprosy, nevus depigmentosus, and tinea versicolor are the five most prevalent hypopigmentary disorders in the pediatric age group.
- This study highlights the significant burden of these conditions in children presenting to dermatology clinics.
Background:
Hypopigmentary disorders are common group of dermatoses in pediatric age group.
Aim:
To study the frequency and patterns of hypopigmentary disorders in children.
Materials And Methods:
This study was a descriptive clinical study spanning over a period of 23 months. A total of 113 children (61 boys and 52 girls) were included in this study.
Results:
The frequency of hypopigmentary disorders among children was 3.28 per 1000 children attending the dermatology out patient department. The mean age of the children was 7.2 years. The mean of age of onset was 7.36 years. Most common hypopigmentary disorder in our study was pityriasis alba (24.7%), followed by vitiligo (20.4%), leprosy (11.5%), nevus depigmentosus (10.18%), and tinea versicolor (6.2%). Others were hypomelanosis of Ito (5), post-inflammatory hypopigmentation (5), pityriasis rosea (4), steroid-induced hypopigmentation (4), lichen sclerosus et atrophicus (3), pityriasis lichenoides chronica (3), lichen striatus (2), oculocutaneous albinism (2), tuberous sclerosis complex (2), pigmentary mosaicism (1), and Griscelli syndrome (1).
Conclusion:
Pityriasis alba, vitiligo, leprosy, nevus depigmentosus and tinea versicolor are the five most common hypopigmentary disorders in children.
