Isolation of keratinophilic fungi from the dust of ferry boats and trains in Italy.
The occurrence of fungi of the genera Epidermophyton, Microsporum, Trichophyton and Chrysosporium in dust collected from 10 ferry boats and 11 railway cars in Italy was studied. Ferry boats: 101 colonies of fungi were isolated. Of the dermatophytes, E. floccosum represented 2.0% of all the colonies isolated, M. canis 3.0%, M. gypseum 5.0% and Tr. mentagrophytes represented 2.0%. E. floccosum was isolated from 2 ferry boats, M. canis from 3, M. gypseum from 4 and Tr. mentagrophytes from 2. Only two ferry boats appeared to be free of pathogenic fungi. Of all the species isolated, Chr. pannorum was the most numerous (45.4%). In all five species of Chrysosporium were isolated. Railway cars: The final destination of the trains, coming from various cities, was Rome's Termini Station. 336 strains were isolated. The following species were found: E. floccosum 3%, Tr. mentagrophytes 4.8%, Tr. tonsurans 0.3%, Tr. ajelloi 0.6%, Trichophyton spp. 3%, M. canis 5% and M. gypseum 1.5%. Seven different species of Chrysosporium were isolated. Chr. pannorum was the most numerous one (71% of all). Regarding the occurrence of dermatophytes, E. floccosum was isolated from 8 of the 11 trains examined, M. canis from 10, M. gypseum from 4, Tr. mentagrophytes from 8 and Tr. tonsurans from only 1 of the trains. All of the trains were positive for pathogenic fungi, ranging from a minimum of 2 species to a maximum of 4.

[Fibrofolliculoma, trichodiscoma and acrochordon. The Birt-Hogg-Dubé syndrome].
The Birt-Hogg-Dubé syndrome is characterized: a) clinically, by an asymptomatic eruption of dome-shaped papules involving the head, neck, chest, back and arms frequently associated with acrochordons; b) histologically, by multiple follicular tumors, namely fibrofolliculomas and trichodiscomas, representing benign proliferations of mesodermal and ectodermal components of the pilar apparatus; c) by the apparent autosomal dominant mode of inheritance. This study is concerned with two families whose various members belonging to two and three generations have the clinical and histological lesions of this syndrome. In several biopsies performed, the main finding was the fibrofolliculoma isolated or associated with perifollicular fibromas; in five biopsies, was noted a typical trichodiscoma associated, in two of them, with a perifollicular fibroma. Clinically, the fibrofolliculomas were indistinguishable from trichodiscomas. We believe that the Birt-Hogg-Dubé syndrome is an autonomous well individualized skin disease. Its existence supports the view of the close interaction between the epithelial and mesodermal components of the pilar complex.
