[Mucormycosis-actinomycosis and caseous dental sinusitis associated with sinusal foreign body]

The authors report an uncommon case of caseous dental sinusitis with infection or superinfection by mocorales and actinomycetes. The patient was healthy, without diabetes mellitus, but was treated for lymphoma 18 years before. This observation leads to a discussion of nosologic, diagnostic and therapeutic features of caseous sinusitis, dental or not, fungal or not, which are often or too often called aspergillosis sinusitis. The recovery of the patient was complete after surgery, amphotericin B and hyperbaric oxygen.
