Abstract:
A 24-year-old male boy presented dermatosis which first appeared acutely after an infection at age 17. Clinical and histopathologic examinations were consistent with a diagnosis of juvenile pityriasis rubra pilaris type III. Treatment with UVB narrow-band led to complete resolution of the dermatitis within 1 year. Pityriasis rubra pilaris is a papulosquamous disorder of unknown etiology, which can be treated with retinoids, methotrexate, cyclosporine, and narrow-band phototherapy.
Insights
Juvenile pityriasis rubra pilaris (PRP) is a rare skin condition. Narrow-band UVB phototherapy effectively resolved a case of type III juvenile PRP in a young male patient.
Area of Science:
- Dermatology
- Phototherapy
Background:
- Pityriasis rubra pilaris (PRP) is a rare papulosquamous disorder of unknown origin.
- Juvenile PRP, specifically type III, presents a unique clinical challenge.
Observation:
- A 24-year-old male presented with a dermatosis that began acutely at age 17.
- Clinical and histopathological findings confirmed juvenile pityriasis rubra pilaris type III.
Findings:
- Treatment with narrow-band ultraviolet B (UVB) phototherapy resulted in complete resolution of the dermatitis.
- Complete resolution was achieved within one year of consistent UVB treatment.
Implications:
- Narrow-band UVB phototherapy is a viable and effective treatment option for juvenile pityriasis rubra pilaris type III.
- This case highlights the potential of phototherapy in managing this rare dermatosis.
- Further research into phototherapy's efficacy in pediatric and adolescent dermatological conditions is warranted.
