The choanal polyp, originating from inferior turbinate, is known to be extremely rare. We reporta case of a 65-year-old woman who was treated for choanal polyp originating from inferiorturbinate. She had felt left nasal obstruction for two weeks. In the endoscopic examination, polypoidtissue covered with the mucopurulent discharge was observed filling the left inferior meatus. An ovoid homogenous enhancing lesion in the left posterior nasal cavity around the inferiorturbinate was observed on CT and MRI. Endoscopic mass excision with partial inferiorturbinectomy was performed under general anesthesia. The pedicle of the polyp was observedon the posterior side of the inferior turbinate. Complete resection including the mucosa aroundthe pedicle of the choanal polyp was performed. The patient was followed up for seven monthswithout any recurrence or complications.

Background and Objectives The purpose of this study is to compare diagnostic outcomeand safety of fine needle aspiration (FNA) and core needle biopsy (CNB) in patients with cervicallymphadenopathy. Subjects and Method This retrospective studies were conducted on 164 cases with cervicallymphadenopathy that had undergone FNA, and 44 cases that had undergone CNB. The cytopathologicalresults from FNA and CNB were compared with the histopathological resultsconfirmed by excisional biopsy in the nodes according to different sizes and radiological levels,respectively. Diagnostic sensitivity, specificity, positive predictive value (PPV), negativepredictive value (NPV), and accuracy were evaluated according to disease entities. Results FNA is more accurate than CNB in most of the sizes and at all cervical levels. However,there is no statistically significant difference between the results of the two tests. Sensitivityand NPV for diagnosis of malignant lymphoma are higher with FNA than with CNB. However, specificity and PPV for malignant lymphoma are higher with CNB than with FNA. Also CNB showed superior sensitivity, PPV and NPV for metastatic lymphadenopathy. Conclusion Although CNB is beneficial in reducing the false negative rate, it still has severallimitations. Since CNB has no statistically significant advantage over FNA, FNA can bea good alternative method with less complication and high diagnostic value for lesions whereCNB is difficult to perform.
