Histopathological Study of Non Neoplastic and Neoplastic Lesions of Larynx

Abstract

Background:The larynx serves to protect the lower airways, facilitates respiration and plays a key role in phonation. Lesions of larynx can be classified into commonly occurring non neoplastic and neoplastic lesions. Materials and Methods: This is a prospective study carried out in department of pathology, GMC Jammu over a period of two years. A total of 90 cases were included in the study. Results: The peak incidence of benign laryngeal lesions occurred in 30-40 years and malignant lesions in 60-70 years .Both benign and malignant lesions were more common in males as compared to females with M:F ratio of 2:1.Vocal polyp(16.7%) being the most common tumor like lesion followed by chronic non specific laryngitis(12.2%).Among the benign tumors squamous papilloma constituted 6.7% cases and in malignant tumors squamous cell carcinoma constituted 52.2% cases. Conclusion: Every tissue removed during laryngeal surgery should be sent for histopathology, as early diagnosis of lesion can lead to effective management.
