“…However, observed nail discolouration may also be greenish-black, bluish-grey, greenish-brown and greenish-yellow [ 6 ]. Fungal melanonychia caused by C. albicans is rare with only a few cases reported so far [ 7 , 8 ]. To the best of our knowledge, onychoscopic features of this condition have not been reported to date.…”

“…Proximal subungual onychomycosis, with infection beginning at the proximal nail fold and extending distally, is a common presentation of onychomycosis as a result of non‐dermatophytic moulds 10 . Furthermore, paronychia is common in nail infections caused by Candida that is capable of melanin synthesis but nail pigmentation more commonly results from activation of host melanocytes caused by paronychial inflammation 20,21 …”

Background Melanonychia refers to brown‐black colour pigmentation due to melanin or not‐melanin deposition in the nail plate. Onychoscopy allows to distinguish if the pigmentation is due by melanin or not. The main causes of non‐melanic pigmentation are subungual haematoma and pigmented onychomycosis. Fungal melanonychia (FM) is rare and may present as diffuse or longitudinal pigmentation. Differential diagnosis includes melanic activation, such as ethnic‐type nail pigmentation or frictional melanonychia, but also versus melanic proliferation, such as nevus or nail melanoma. Fungal melanonychia can be due to a colonisation by fungi with black variant or by melanin activation due to inflammation of fungal invasion. Objectives The aim of paper is to increase clinical and dermoscopic knowledge of this increasingly frequent disease. Methods In this retrospective observational study, twenty patients with dermatophytic melanonychia were collected, with available clinical and dermoscopic pictures. The diagnosis of dermatophytic melanonychia was made based on clinical manifestation and mycological examination. KOH smear was performed in all cases. For each patient, clinical data included: age, gender, type of melanonychia and involved fingers. Results This study aimed to show increased incidence of dermatophytic melanonychia and its correct management. In addition, we reviewed our collected cases and described the clinical and dermoscopic features of dermatophytic melanonychia. Conclusions The results of this study showed that physicians should keep in mind the diagnosis of this increasing disease, and that it cannot be performed relying only on clinical grounds. We would like to highlight the importance of tools as KOH examination, culture and dermoscopy.

The clinical manifestation of superficial candidiasis varies depending on the infectious sites and causative Candida species that brings a great challenge to diagnose or treat without mycological or pathological evidence in clinical settings. Oral mucosal candidiasis and onychomycosis are most common types of superficial candidiasis. Typically, oral mucosal candidiasis manifests as white or erythematous thrush coated on the tongue and other interior oral cavity; and onychomycosis caused by Candida spp. presents with thick, fragile, or cracked fingernails or toenails in yellow or white discoloration. Here, we report one case of patient with a black hairy tongue caused by Candida tropicalis and one case of greenish discolored onychomycosis caused by Candida parapsilosis. The cases of superficial candidiasis with the same discolored lesions were searched in literature and compared with our cases in clinical manifestation, causative pathogen and treatment. These cases highlight the importance of mycological diagnosis for identifying non-Candida albicans Candida species (NCAC) in superficial infections to guide an effective therapy.
