PATHOGENIC MOULDS AND YEASTS. 483 Recently Kartulis, in Alexandria, has described al)out a hundredcases of a skin affection occurring in the gluteal regions of men andcharacterized by an elongated finger-like swelling, which breaks andemits a purulent discharge forming an unhealed sinus. In the dis-charge and surrounding tissues are numerous blastomycetes whichKartulis after cultivation and study considered a variety of the ordinaryfermenting yeast (Saccharomyces cerevisia?—Hansen). The caseswere cured bv excising the growth. Kessler reported a skin lesion in an infant (see Fig. 165) probablydue to a similar blastomycete, since the lesions healed after treatmentwith potassium iodide. The description of the yeast isolated is tooincomplete to identify it. Fio. 165. Blastomycosis in iutant of 8 months, allowing lesion on left cheek. (Kessler.) Some years ago the attempt was made to connect the develop-ment of cancerous growth with blastomycetes. This was due in ameasure to a certain similarity between the yeasts and the cell in-clusions or so-called parasites of cancer, and, further, to the factthat when yeasts are injected into the animal body tumor-like nod-ules are often developed at the site of inoculation and in the internalorgans. But these nodules are not tumors in the pathological senseof the term, but merely masses of blastomycetes mixed with inflam-matory tissue proliferations to a very variable degree. At the presenttime Sanfelice and his pupils are perhaps the only ones who regardthe thickenings produced in the tissues by Saccharomijccs neoformansas true tumors. His work, however, is not at all convincing. Bi
