[Melanonychia: The purpose of a case of ungual mycotization mimicking melanoma].
BACKGROUND
Phialophora sp. dematiaceous fungus frequently isolated from soil and organic debris from animals and plants. There have been no reports of nail involvement caused by this fungus. We report the case of a 77-year-old male with blackish-brown pigmentation involving a single finger for one year. The identification of the fungus was determined by macromorphological and micromorphological study of the colony and we discuss the clinical, microbiological, differential diagnosis, and treatment.


CONCLUSIONS
We describe the first case of nail infection caused by Phialophora sp.
