Area of Science:

• Pediatric Dermatology
• Clinical Case Study

Background:

• A 6-month-old boy presented with a persistent, pruritic rash.
• The eruption affected the scalp, extremities, and inguinal creases.
• Previous treatments with topical corticosteroids and antifungals were ineffective.

Purpose of the Study:

• To evaluate a persistent, pruritic eruption in an infant.
• To determine the underlying cause of the rash unresponsive to standard therapies.

Main Methods:

• Clinical examination of the infant's skin.
• Diagnostic skin biopsy was performed for histopathological analysis.

Main Results:

• Examination revealed erythematous to yellow, scaly, greasy plaques on the scalp and ears.
• Purpuric papules were noted in the inguinal creases.
• Hyperkeratotic yellow papules were present on the extensor extremities.

Conclusions:

• A diagnostic skin biopsy was crucial for identifying the cause of the persistent, pruritic eruption.
• The case highlights a challenging pediatric dermatology presentation requiring further investigation.
