The reddish, ringworm-like lesions with active borders localized to high-moisture body folds (groin, axillae, umbilicus) are classic for a dermatophyte infection. Psoriasis typically presents with well-demarcated, thick plaques with silvery-white scales on extensor surfaces, which does not align with this patient's symptoms.
The fact that the patient has seen no significant improvement after 15 days of oral itraconazole and topical eberconazole is increasingly common due to the rise of drug-resistant dermatophytes, or it may simply be that the infection requires a longer course to achieve clinical clearance.
Next Steps
Antifungal Resistance: There is a well-documented, surging prevalence of Trichophyton mentagrophytes and Trichophyton indotineae strains that exhibit partial or high resistance to oral triazoles (like itraconazole). Inadequate Treatment Duration: Tinea infections in deep body folds routinely require 4 to 6 weeks of continuous therapy for complete mycological cure. Fifteen days is often insufficient to witness substantial regression in resistant cases. Local Microenvironment: High humidity, sweat retention, and friction in the groin and belly button areas create a highly favorable environment for fungal replication, actively countering the efficacy of topicals.
