Actinomycosis in otorhinolaryngology. Apropos of a case with localization in the nasal cavity

: 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.
