[Actinomycosis in otorhinolaryngology. Apropos of a case with localization in the nasal cavity]. / L'actinomycose en ORL. A propos d'un cas localisé aux fosses nasales.

The authors report an atypical case of actionomycosis implanted in the nasal cavity and occurring twenty years after septum surgery. Treatment by penicillin and surgical excision gave a good result. Cervicofacial actinomycosis is caused by actinomyctes which usually lives as a saprophyte in the oral cavity. A trauma is often found in the previous history. Diagnosis with tumors and abscess may be difficult. The histopathological examination shows typical aspects of the granuloma (gram+ and Grocott+) and the bacteriological isolation of the germ is difficult to obtain. Penicillin associated with surgical excision is the best therapy, but high doses must be used for a long time. The literature is reviewed without finding such a case.
