Excellent Response of Dermatophytoma and Nail Splitting to Nail Plate Debridement Plus Topical Ciclopirox Olamine 1% Solution.

ABSTRACT

Onychomycosis often presents as thickened, discolored nails. Usually, one or both great toenails are affected. Eventually, the nail plate becomes friable and may split and break up, often due to trauma or invasion of the plate by dermatophytes that have keratolytic properties. Dermatophytoma is a unique feature of onychomycosis that occurred by abundant fungal filaments and spores forming a fungal ball under the nail plate. It is often refractory to traditional therapy. Based on the clinical and mycological examination, a case of onychomycosis in a 45-year-old woman presented as dermatophytoma with longitudinal nail splitting caused by Trichophyton rubrum is presented. The case was successfully treated with nail plate debridement plus topical ciclopirox olamine 1% solution. Nail debridement was performed using a 15-scalpel blade to remove the affected nail portion with the underlying subungual debris to enhance the effect of topical ciclopirox 1% solution which was then applied 3 times daily to the debrided area. Follow-up visits with nail photography were planned every 2 weeks after the procedure to check treatment progress. A complete clinical resolution was achieved after 5 months. This treatment option can be advocated for similar nail conditions avoiding unnecessary and expensive lines of treatment.
