[Onyxis caused by Malassezia (Pityrosporum) ovalis].
Onychia by Malassezia ovalis are described for the first time. They are observed mainly on the hands of young or adult women with semiological characteristics of aphlegmatic onycholysis. In clinical materials M. ovalis is seen as yeasts only or as yeasts and typical hyphae. Cultures are easily obtained on Sabouraud medium containing 2% of bile. It is thought that these lesions are example of an opportunistic mycosis since predisposing local factors are almost always present. Oral or topic treatment with imidazole derivatives has shown to be effective.
