Clinical Case of 9-Year- Old Boy With Non-Specific Lesions

Abstract

Objectives: A 9-year-old boy presented to the emergency de-partment with a chronic rash persisting for 3 months, alongsidea new rash that had appeared over several days. He had beenpreviously healthy with no chronic conditions. The patient en-gages in motocross and uses jumpsuits that increase sweating.The patient's mother reports frequent scratching due to this con-dition. Upon examination, the patient exhibited elevated, dry,crusty, itchy lesions on the right elbow, left arm, and both shins.Additionally, small, skin colored papular rashes were noted onthe knees and elbows. Despite treatment with oral and topicalantibiotics, permethrin, systemic antibiotics, corticosteroids,oral antihistamines, and topical glucocorticoids, no significantimprovement was observed. The patient was subsequently hos-pitalized for intravenous antibiotic therapy and glucocorticoids,resulting in resolution of both types of rashes during hospital-ization. However, a few days later, the patient returned to theoutpatient clinic with a new rash on his right arm. The rash wasalso itchy, elevated, erythematous.Method:Results: A skin biopsy was performed on the new erythema-tous, elevated lesion on the right arm, revealing dermal fibrosisand lymphocytic infiltration, suggestive of an process.Discussion: The clinical findings are consistent with nummu-lar eczema, which may have led to intense itching and subse-quent keloid formation. The other rash regressed spontaneously,which may help differentiate it from phrynoderma or coxsackieviral infection.This case illustrates the diagnostic challenges in pediatric der-matology and allergology, emphasizing the importance of thor-ough evaluation and consideration of underlying conditions thatmay exacerbate chronic skin issues, as well as the need for ongo-ing monitoring and tailored treatment strategies.
