Le mélanome malin: une tumeur rare des fosses nasales - à propos d'une série de 10 cas

Le mélanome malin des fosses nasales est une tumeur rare mais très agressive, de traitement complexe et de pronostic défavorable. Son traitement relève en principe d'une prise en charge essentiellement chirurgicale complétée par une radiothérapie. L'objectif de ce travail est de rapporter les caractéristiques cliniques, thérapeutiques et évolutives des mélanomes des fosses nasales. Nous avons a...

Development of Trichosomoides nasalis (Nematoda: Trichinelloidea) in the murid host: evidence for larval growth in striated muscle fibres

Trichosomoides nasalis (Trichinelloidea) is a parasite of Arvicanthis niloticus (Muridae) in Senegal. Female worms that harbour dwarf males in their uteri, occur in the epithelium of the nasal mucosa. Young laboratory-bred A. niloticus were either fed females containing larvated eggs or intraperitoneally injected with motile first-stage larvae recovered from female uteri. Both resulted in succe...

Trichosomoides nasalis (Nematoda: Trichinelloidea) in the murid host Arvicanthis niloticus: Migration to the epithelium of the nasal mucosa after intramuscular development

Knowledge of the biology of the trichinelloid subfamily Trichosomoidinae is poor. Trichosomoides nasalis is a common parasite of Arvicanthis niloticus (Muridae) in Senegal, and a procedure for experimental infections has been established. It has been demonstrated that larvae develop in striated muscle fibres, similar to Trichinella spp., but they are not arrested in the first stage, and they re...
