Candida onychomycosisL60.8

Candidosis of the nail plate without destruction of the keratin. Typical are grey-black or also greenish (in case of bacterial coinfection) discolorations of the lateral nail plate due to diffusion of microbial dyes.

Yeast fungi do not possess their own keratinases; they cannot therefore attack an intact nail. Candida onychomycosis develops either in mixed infections of the paronychium (paronychia) or as a result of Candida paronychia. Yeast fungi are most frequently isolated from fingernails.

Chronic, usually moderately painful redness and swelling of the nail fold. The cuticle loses its adhesion to the nail plate so that foreign bodies can penetrate. Often it is completely missing. Bacterial superinfections occur frequently.

On pressure or spontaneously, thick white material consisting of horn components, pus and fungal elements can empty out of the nail pocket. With longer existence it can come to growth disturbances with thickening, discoloration, surface ripening, as well as to a softening and lysis (onycholysis) of the nail plate. In this constellation a candida onychomycosis is possible. Not infrequently the nail is greenish or grey-greenish discolored. This dyschromasia occurs when a bacterial superinfection with Pseudomonas aeruginosa or Klebsiellen is present.
