Introduction: A variety of non-neoplastic and neoplastic conditions involving the nasal cavity and nasopharynx are commonly encountered in clinical practice. The presence of a mass in the nose and paranasal sinuses may seem to be a simple problem; however it raises many questions about the differential diagnosis. Aim: The objectives of the study were to identify various pathological conditions that present with sinus or nasal mass, to understand their varied clinical behavior, to know the distribution of various lesions among the different age and sex groups, and to study the management of sinonasal masses and its outcome on follow-up. Methods: A prospective study was carried out which included 50 patients of any age and sex presenting with nasal symptoms. Complete history was taken and full clinical examination was carried out. Clinical features with histologically corelated. Results: Majority of the patients with sinonasal masses were in the age group 41–50 years with male predominance. Nasal obstruction was the most common presentation. Most common benign lesion was nasal polyp and most common malignant lesion was squamous cell carcinoma. The clinical diagnosis in most of the cases (92%) cases correlates with the histological diagnosis in the present study. Conclusion: Sinonasal neoplasms have wide range of possibilities, early diagnosis with prompt treatment is necessary for these patients which will decrease the burden of morbidity and mortality. The clinicopathologic features are necessary for any neoplastic lesion in nasal cavity for early recognition and treatment.
