Fungal Melanonychia Caused by Cladosporium Species: A Case Report / 대한의진균학회지

ABSTRACT

Fungal melanonychia is typically associated with onychomycosis and is known to be a relatively uncommon nail disorder. The known pathogens causing fungal melanonychia include both dematiaceous and non-dematiaceous fungi. Here we describe the case of a 60-year-old man with a 1-year history of nail discoloration in both index fingers. The possibility of subungual neoplasm was excluded by histological examination. Subsequent mycological examination revealed the presence of Cladosporium species in the lesion. The patient was successfully treated with oral itraconazole.
