Study of Histopathology of the Tumour like Lesions and Tumours of the Oral Cavity

Aims To study spectrum, clinical features and histopathology of different lesions of oral cavity. Settings and Design This was a both retrospective and prospective study carried out in the department of pathology over a period of 5 years. Histopathological examination of a total of 70 cases of oral cavity lesions over a period of 5 years was done. Results 42 (60 %) were tumours and 28 (40 %) were tumour like lesions. Most common tumour like lesion was pyogenic granuloma. Among tumours malignant tumours were most common. In benign tumours most common were hemangioma. Premalignant lesions included leukoplakia and erythroplakia. Amongst the malignant tumours most common were squamous cell carcinoma. Amongst the squamous cell carcinoma maximum were well differentiated. The peak incidence of tumour like lesions was in the age group of 20-40 and of tumours of oral cavity in greater than60 yrs age group. Male to female ratio in tumour like lesions was 1.81 while in tumours of oral cavity it was 1.61. Smoking was the most common habit both in tumours of the oral cavity and in tumour like lesions. Conclusions. Histopathology is an important tool in the diagnosis and management.
