“…Newer diagnostic techniques like conventional polymerase chain reaction (PCR), real-time PCR techniques, and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) are now dependable for performing the in-situ identification of dermatophytes, yeasts, and NDMs in OM provided that adequate nail material is collected. Non-invasive methods such as optical coherence tomography, confocal laser scan, and advanced microscopic methods including phase contrast microscopy and hard X-ray microscopy, help in early diagnosis and better management of infection [ 11 ].…”

Onychomycosis (OM) is a common disease of nails. It is a major public health issue worldwide due to its increasing prevalence. Moreover, OM is associated with substantial consequences including physical and psychological outcomes. Dermatophytes are a group of keratinophilic fungi that account for more than half of OM incidences. However, yeasts and non-dermatophyte molds represent about one-third of OM infections that have recently shown an increasing trend. The knowledge of OM appears to be low among people, especially those who live in rural areas. Therefore, most cases remain undiagnosed, which in turn leads to the spread of fungus within the individual and to other susceptible people. We report a case of total dystrophic onychomycosis involving all the fingernails and toenails in an 87-year-old female patient caused by non-dermatophyte molds.

Fusarium species are an emerging cause of onychomycosis, and the number of cases has dramatically increased in recent decades worldwide. This review presents an overview of the onychomycosis cases caused by Fusarium species and diagnosis and treatment that have been reported in the literature. The most common causative agent of onychomycosis is F. solani species complex, which accounts for 11.68% of the cases of Fusarium onychomycosis, followed by the F. oxysporum species complex (164 out of 1669), which is accounted for 9.83% of the total. F. fujikuroi species complex (42 out of 1669) and F. dimerum species complex (7 out of 1669) are responsible for 2.52% and 0.42 cases, respectively. Fusarium nail infections were reported in patients aged range 1–98, accounting for 5.55% (1669 out of 30082) of all cases. Asia has the highest species diversity of Fusarium onychomycosis (31.51%). South America accounts for 21.09%, and the most common causative agent is F. solani (19.32%), followed by F. oxysporum species complex (15.63%). Europe accounts for 4.90% of cases caused by F. oxysporum, followed by F. solani. Africa accounts for 23.87% of the cases due to the F. solani species complex, followed by F. oxysporum and F. fujikuroi. Distal and lateral subungual onychomycosis was the most common clinical symptom accounting for 58.7% (135 out of 230) of the cases. Data analysis relieved that terbinafine and itraconazole are active treatments for Fusarium onychomycosis. For a definitive diagnosis, combining of direct examination, culture and sequencing of the elongation factor of translation 1α are recommended. Accurate identification of the causative agents of onychomycosis due to Fusarium species and antifungal susceptibility testing is essential in patient management.
