Squamous cell carcinoma originating from the nasal septal perforation: a rare nasal tumor.

Primary squamous cell carcinoma of the nasal septum is an extremely rare malignancy. In this article, we report a case of 52-year-old female with a complaint of nasal obstruction along with occasional nasal bleeding for one year. Endoscopy showed a 2.5x2 cm perforation originating from the anterior nasal septum. Incisional biopsy result was reported as squamous cell carcinoma. The tumor was removed by functional endoscopic surgery. Histopathological examination revealed squamous cell carcinoma with safe surgery borders. No recurrence and complications were noticed after one year of follow-up. The functional impact of the treatment with high mortality rates highlights the importance of early diagnosis. We recommend the differential diagnosis of septal perforation and early wide surgical excision for such cases.

Quantifying the expression of VEGF using qRT-PCR, evaluation of MVD and their correlation with clinicopathological factors in laryngeal squamous cell carcinoma.

OBJECTIVES: In this study we quantified the expression of vascular endothelial growth factor (VEGF) using quantitative real-time polymerase chain reaction in laryngeal squamous cell carcinoma (LSCC) tissues and evaluated the correlation between the level of VEGF and microvessel density (MVD), and clinicopathological factors. PATIENTS AND METHODS: Twenty-seven patients with LSCC undergoing total or partial laryngectomy at the Ear, Nose, and Throat and Head and Neck Surgery Department of the Izmir Tepecik Training and Research Hospital between September 2006 and July 2008. There was no VEGF expression in two patients that were excluded from the study. Twenty-five patients (24 males, 1 female; mean age 61 years; range 43 to 82 years) were included in this study, but MVD levels of 10 patients could not be determined. RESULTS: As defined by the 2003 American Joint Committee on Cancer (AJCC) TNM classification, seven patients (28%) were stage 1, six patients (24%) were stage 2, four patients (16%) were stage 3, and eight patients (32%) were stage 4. Thirteen patients (52%) had well-differentiated (G1) tumors, and twelve had moderately differentiated tumors. Among the 15 patients for whom the MVD was determined, the median value was 48, with a (range 13-78; vessels / 3.76 mm2). Among the 25 patients for whom the VEGF level was determined, the median value was 0.035 vessels / 3.76 mm2 (range 0.010-0.127). CONCLUSION: We could not find a statistical correlation between clinicopathological factors and either VEGF or MVD. Our study demonstrates that VEGF is expressed by LSCC.
