ABSTRACT
Sinonasal undifferentiated carcinoma (SNUC) is a rare tumor which is aggressive in nature, has a different clinical course in contrast to sinonasal carcinoma and poor prognosis. Here, we are reporting first case of isolated frontal SNUC which was managed by upfront surgery followed by adjuvant treatment. We want to emphasize the importance of early presentation and timely intervention in form of conservative surgery in this highly aggressive tumor.
ABSTRACT
ABSTRACT: Resection of primary in carcinoma tongue is challenging as the tumor often spreads submucosal and deep in muscles. There are various Intraoperative tools available to guide tumor resection margins. We studied the use of intraoperative ultrasound-guided resection for obtaining free deep resection margins in cases of oral carcinoma tongue. To assess the feasibility of resection of tongue tumor using intraoral ultrasound intraoperatively. 5 patients of oral tongue squamous cell carcinoma were included in this prospective pilot study. Intraoral ultrasound-guided resection of the primary tongue tumor was done. The surgeon moved the probe over the tumor and focussed on the point of maximum invasion by the tumor. A 26 G needle was passed in the tongue at a point that was 10 mm away from the deepest point of infiltration. It marked the deepest plane of resection. Following the above marking, a resection of tumor was done. Deep surgical resection margin was found to be >5 mm (free) in all the USG-guided surgically resected primary tongue tumors on histopathological examination. We have found intraoperative ultrasonography a useful tool for the surgical resection of primary tongue tumours.
