Unilateral pityriasis rosea in a child

Area of Science:

• Dermatology
• Clinical Case Reports

Background:

• Pityriasis rosea typically presents with a generalized rash.
• Unilateral presentations of pityriasis rosea are exceptionally rare in medical literature.

Observation:

• A pediatric patient exhibited an acute onset of scaly eruptions.
• The rash was clinically diagnosed as pityriasis rosea.
• The eruptions were confined to the right side of the body, affecting the waist, thigh, forearm, and leg.

Findings:

• The case demonstrates an atypical, unilateral variant of pityriasis rosea.
• The distribution of lesions was strictly limited to one hemibody.

Implications:

• This case underscores the importance of recognizing rare variants in dermatological diagnosis.
• It contributes to the limited body of literature on unilateral pityriasis rosea.
• Highlights the need for considering atypical presentations in pediatric dermatology.
