الملخص EN

Objective: study the ؛ncidenee, distribution and histology of various polypoidal lesions in the nasal eavity in this geographie area.

Setting: Department of ?athology, MS Ramaiah Medical College, Bangalore, India.

Subjects and Design: A total of 145 polypoidal lesions in the nasal cavity received for histopathology over the last 8 years.

Relevant clinical data was recorded in each case.

Results: Of the 145 lesions examined, 102 (70.3%) were non-neoplastic while 43 (29.7%) were neoplastic; 21 (48.8%) ofthese being benign and 22 (51.2%) malignant.

True nasal polyps, both inflammatory and allergic, together comprised 86 (59.2%) of the polypoidal lesions in the nasal cavity.

Angiofibroma was the most frequent in the benign tumor category, accounting for 15 of the 22 benign tumours encountered (71.5%).

Malignant tumours involved the maxillary sinus in most cases.

Of the malignant tumors, majority (9, ie.

40.9%) were of the squamous cell variety.

Non-neoplastic lesions and benign tumours were more common in younger age groups whereas malignant tumours were more common in older patients.

Except for angiofibroma which was distinctly preponderant in young males, none of the other lesions showed significant sex predilection.
