| Popis: | A 68-year-old woman consulted our clinic exhibiting a bilateral nasal obstruction which had lasted for 2 months. Anterior rhinoscopic examination revealed the presence of necrotic tumor which was raised from the posterior portion of the right nasal cavity or epipharynx. Since only slight tumor reduction was obtained through 40Gy of radiotherapy, surgical excision was done endonasaly using an endoscope. Intra-operative findings indicated that the tumor was raised from the posterior portion of the right inferior turbinate. En bloc resection was carried out, but viable tumor cells were exposed at the surgical margin. An additional 30Gy of post-operative radiotherapy and lateral nasal wall resection using a lateral rhinotomy approach were carried out. Moreover, right neck dissection was done for right cervical lymph node metastasis.Surgical excision with a wide margin is the most desirable method of treatment for this kind of tumor. Though this method is difficult to carry out in the head and neck region, we suggested that excision with marginal margin combined with radiotherapy could produce good results. |
