title: A kerion celsi caused by Microsporum gypseum: unusual direct mycological examination.
abstract: A case of kerion celsi caused by Microsporum gypseum is documented. The patient was a 6-year-old girl with a 2-cm purulent lesion on the scalp. Direct mycological examination of the hair showed hyphae with extremely numerous spindle-shaped macrospores. The species identification was confirmed by 28S ribosomal DNA sequencing. The presence of numerous macrospores is unusual in direct mycological examination, but could be an indication for M. gypseum.
