The osseous metaplasia in nasal polyps is a rare but benign disease. The image of increased contrast inside the lesion can be seen on CT scan. The diagnosis is based on histopathological results. In this report, we present a case of a 63-year-old female patient with nasal polyps with very special bone growth forming a bone shell surrounding almost the entire polyp mass, which is rarely reported in the literature before. This report on "Rare bone growth in nasal polyps and literature review" aims to describe the clinical and paraclinical manifestations of a patient, and discuss some reports in the literature that have been encountered, which can help otolaryngologists pay attention and accumulate medical records that will be encountered about this special disease and can be studied further to contribute to better diagnosis and treatment, as well as help differentiate from other dangerous diseases.
