[Study on a Trichophyton quinckeanum species with a distinctly marked fluorescence of the scutulum in animal experiments].
A vesicular skin lesion which existed since 1 week in the lower part of the leg of a 45-year-old woman appeared to be caused by fungus which was identified as Trichophyton quinckeanum (Zopf) MacLeod & Muende. The patient could not state to have had contact with animals. Peroral administration of griseofulvin and local application of 2% salicyl--5% sulfur--vaseline alternate with tonoftal cream healed the lesion completely. The fast growing fungus produced white, convoluted colonies with a brown, lat er wine-red reverse. Globose and club-shaped, one- and two-celled microconidia were formed especially 'en thrse'. The majority of the thin-walled macroconidia had rounded apices but a fusiform type of spore was also seen. Germination of the macroconidia was frequently observed. Experimental infection into the dorsal skin of white laboratory mouse produced a scutulum with a bright yellow later green fluorescence in Wood's light. The taxonomy of Trichophyton quinckeanum is briefly discussed.
