Chronic rhinorrhea revealing an actinomycotic rhinolithiasis with ectopic tooth

Intranasal ectopic tooth is a rare nidus for a rhinolith where local infection may be concomitant. No description of the triple association 'actinomycotic rhinolithiasis ectopic tooth' could be found in the medical literature. Classically, the Actinomyces species are sensitive to regimens of penicillin from 6 to 12 months or longer. Immunocompetent patients can benefit from shorter courses of antibiotic therapy, such as ciprofloxacin, with a favourable outcome. The authors describe the case of a 25-year-old man who presented with an actinomycosis chronic discharge revealing actinomycosis associated with rhinolithiasis and ectopic tooth. They attempt to explain the likely mechanism of occurrence of this triple association.
