title: Familial antrochoanal polyposis--a case report.
abstract: Antrochoanal polyps are rare lesions. Since Killian's first report in 1906, several pathogenic mechanisms have been described. However, the aetiological factors are still not fully understood. In this paper we present the first report of antrochoanal polyps occurring in siblings, suggesting a possible familial aetiology.
