What Types of Specialists Treat Fungal Nail Infections?
Fungal nail infections are often treated by a person's primary-care doctor. Other specialists who may treat these infections include dermatologists, podiatrists, and infectious-disease doctors.
What Is the Prognosis of a Fungal Nail Infection?
Several studies with the newer drugs (itraconazole or fluconazole) show significant cure rates, with fingernails having the most favorable prognosis. A cure may occur in some individuals with toenail infections after consistent lengthy treatments over many months. Unfortunately, most people will have some complications such as residual nail changes or some discoloring, and about half will experience nail reinfection. Regrowth of toenails may take over a year to occur.
Summary of Common Types of Fungal Nail Infection
Characteristics of Common Types of Fungal Nail Infection
|Frequency||Most common||Generally uncommon but frequent in AIDS patients||10% of cases of OM|
|Progress of infection||Infection begins with invasion of the space under the nail edge where the nail separates from the nail bed (called the hyponychium)||Infection begins at the nail fold (where the nail meets the finger or toe) and affects newly forming nail||Infection begins at the surface of the nail (nail plate) and progresses to deeper layers|
|Clinical appearance||Separation of the nail from the nail bed (onycholysis), thickening of the area under the nail (subungual hyperkeratosis)||Subungual hyperkeratosis, white discoloration (leukonychia), separation of the nail from the nail bed (onycholysis), and destruction of the nail unit||White areas on the nail surface, eventually involving the entire nail surface|
|Most common causative organism||Trichophyton rubrum||Trichophyton rubrum||Trichophyton mentagrophytes, Aspergillus terreus, Acremonium roseogriseum, Fusarium oxysporum|
|Affected nails||Toenails most commonly affected but may affect fingernails as well||Much more common on the toenails, rarely affects fingernails||Mainly affect toenails|
The term total dystrophic onychomycosis is not a subtype, but is, instead, the final stage of any of the previously described forms of fungal nail infection, candidal fungal nail infection, or both
