title: [Presence of sexual forms (cleistothecia and Hülle cells) in a case of human maxillary sinus aspergillosis caused by Aspergillus nidulans in association with Aspergillus fumigatus].
abstract: The authors observed, in a biopsic sample from a human maxillary sinus, the coexistence, in parasitic stages, of two different Aspergillus species: A. fumigatus and A. nidulans. After having described the morphologies of each species, in sections on slides, and particularly those of cleistothecia and Hülle-cells for the second, they draw attention to the three interests of such an observation: -- rarety of observing Aspergillus nidulans in a parasitic stage, in spite of its particular thermotolerant character. -- association of two different Aspergillus species in a same sample, in parasitic stages, observed in man for the first time, at least according their informations. -- presence of reproductive sexual forms, observed in vivo for the first time, in an Aspergillus species.
