Erythematous Plaques and Nodules in a Child

Area of Science:

• Dermatology
• Pediatric Dermatology
• Rare Diseases

Background:

• Erythema elevatum diutinum (EED) is a rare chronic vasculitis.
• Typically affects adults, with pediatric cases being exceptionally uncommon, especially in boys.
• Common EED manifestations include nodules, papules, and plaques; vesiculobullous variants are rarely documented.

Purpose of the Study:

• To report a rare pediatric case of erythema elevatum diutinum (EED).
• To highlight an atypical vesiculobullous presentation of EED in a child.
• To discuss treatment outcomes in a pediatric EED patient.

Main Methods:

• Case report of a 10-year-old boy with a 2-month history of pruritic plaques and nodules.
• Clinical presentation included erythematous papules evolving into painful ruptured vesicles.
• Diagnosis of EED was established based on clinical findings.

Main Results:

• The patient presented with an unusual vesiculobullous form of EED.
• Improvement was observed with the application of topical corticosteroids.
• This contrasts with dapsone, the conventional treatment for EED.

Conclusions:

• Pediatric erythema elevatum diutinum (EED) is rare and can present atypically.
• Topical corticosteroids may be an effective treatment option for pediatric EED.
• Long-term management and monitoring are crucial due to the chronic nature of EED and potential for recurrence.
