Special Issue Information

Dear Colleagues,

This Special Issue provides an in-depth look at the latest research and developments in the field of cutaneous mycosis. Cutaneous mycosis refers to fungal infections of the skin, hair and nails, and can be caused by a variety of different fungi. One group of fungi that is particularly important in cutaneous mycosis comprises dermatophyte fungi (Microsporum spp., Trichophyton spp., Epidermophyton spp.) that cause dermatophytosis. These fungi, due to their capacity to utilize keratin as a main nutrient for their metabolism, can cause a range of skin and nail infections, known as tinea capitis, tinea corporis, tinea pedis, tinea cruris, tinea unguium, etc. Other filamentous fungi (i.e., Scopulariopsis spp., Acremonium spp.) and/or yeasts can cause cutaneous infections named dermatomycoses, similar to dermatophytosis. Another group of fungi that is important in cutaneous mycosis consists of dematiaceous filamentous fungi. These fungi are characterized by their darkly pigmented cell walls in iphae and/or conidia, and include genera such as Alternaria and Cladosporium.

The articles in this Special Issue cover a wide range of topics related to cutaneous mycosis, including the epidemiology and pathogenesis of these infections, as well as the latest developments in diagnosis and treatment. The issue also includes several case reports that provide valuable insights into the clinical presentation and management of these infections.

Therefore, "Advances in Cutaneous Mycosis" is an important resource for researchers, clinicians and other healthcare professionals who are interested in these common, and often challenging, infections.

Fungal melanonychia is an uncommon condition, most typically caused by opportunistic melanin-producing pigmented filamentous fungi in the nail plate. In the present study, the clinical characteristics of patients diagnosed with fungal melanonychia were analyzed through a systematic review of cases reported in the literature. The MESH terms used for the search were “melanonychia” AND “fungal” OR “fungi” through four databases: PubMed, SciELO, Google scholar and SCOPUS. After discarding inadequate articles using the exclusion criteria, 33 articles with 133 cases were analyzed, of which 44% were women, 56% were men and the age range was between 9 and 87 years. The majority of cases were reported in Turkey followed by Korea and Italy. Frequent causal agents detected were Trichophyton rubrum as non-dematiaceous in 55% and Neoscytalidium dimidiatum as dematiaceous in 8%. Predisposing factors included nail trauma, migration history, employment and/or outdoor activities. Involvement in a single nail was presented in 45% of the cases, while more than one affected nail was identified in 21%, with a range of 2 to 10 nails. Regarding the clinical classification, 41% evidenced more than one type of melanonychia, 21% corresponded to the longitudinal pattern and 13% was of total diffuse type. Likewise, the usual dermoscopic pattern was multicolor pigmentation. It is concluded that fungal melanonychia is an uncommon variant of onychomycosis and the differential diagnosis is broad, which highlights the complexity of this disease. Full article
