Opportunistische filamentöse Mykosen: Aspergillose,Mukormykose, Phäohypho‐ und Hyalohyphomykose

Opportunistic filamentous mycoses are widely distributed all over the world. They are rarely observed in Europe but are common in developing countries. The most common are the aspergilloses (due to Aspergillus spp.) mostly in neutropenia and immunosuppression; the mucormycoses characterized by rapid progression in patients with diabetic ketoacidosis; the phaeohyphomycoses due to pigmented fungi causing either a mild superficial or a very serious deep disease and the hyalohyphomycoses due to hyaline filamentous fungi (Fusarium spp., Pseudallescheria spp., Scopulariopsis spp.). Cutaneous manifestations are usually secondary to dissemination from pulmonary or visceral disease; primary cases are less frequent and due to direct inoculation into the skin. We review epidemiological, clinical, diagnostic, and therapeutic data on the four most important opportunistic filamentous mycoses: aspergillosis, mucormycosis, phaeohyphomycosis and hyalohyphomycosis.
