Dermatophytomas: Clinical Overview and Treatment

Area of Science:

• Mycology
• Dermatology
• Pharmacology

Background:

• Dermatophytomas are hyperkeratotic fungal masses in the subungual space, presenting as dense white or yellow deposits.
• Diagnosis can be achieved through microscopy, histology, dermoscopy, and optical coherence tomography.
• Fungal mass density and potential biofilm formation may impede drug penetration, reducing the efficacy of oral therapies like terbinafine and itraconazole.

Purpose of the Study:

• To review the challenges in treating dermatophytomas, particularly resistance to conventional therapies.
• To explore the potential efficacy of newer topical and oral antifungal agents.

Main Methods:

• Literature review of diagnostic methods for dermatophytomas.
• Analysis of pharmacological properties and clinical data for antifungal treatments.
• Evaluation of treatment strategies, including debridement and novel drug therapies.

Main Results:

• Topical antifungals (tavaborole, efinaconazole, luliconazole) may effectively treat dermatophytomas via transungual and subungual routes.
• Fosravuconazole (F-RVCZ) demonstrates an improved pharmacological profile compared to ravuconazole, suggesting potential as an alternative oral therapy.
• Combination therapy (drug treatment with debridement) is often recommended for enhanced efficacy.

Conclusions:

• Improved treatment options are crucial due to increasing resistance to traditional antifungal therapies for dermatophytomas.
• Newer topical agents and improved oral medications like fosravuconazole offer promising alternatives for managing dermatophytomas.
