Abstract
ABSTRACT
Background
Benign nasal and paranasal sinus masses are commonly encountered in clinical practice.
Though benign, certain nasal polyps, fungal sinusitis, hemangiomas and fibro-osseous
tumors can present with locally destructive features and deformities, mimicking
malignancies at once.
Objective
This study was carried out to recognize the great variety of benign nasal lesions and
their frequency in our region.
Methods
A retrospective chart analysis of cases presenting as mass in nose and paranasal
sinus that underwent surgery over three years duration at our institute was done. A
provisional diagnosis was made after clinical assessment and radiological investigations,
but the final diagnosis was established after histopathological examination.
Results
A total 331 cases presented as masses in nose and paranasal sinus presented during the
period. The clinicopathological examination aided by endoscopic and imaging studies
revealed the non neoplastic benign masses in 293 and neoplastic masses in 38. Polyps
were the commonest lesions constituting 70% cases followed by rhinosporidiosis in
10%. Fungal sinusitis, squamous papillomas, hemangiomas and inverted papillomas
were found to be in order of 4.5%, 4%, 3.5% and 3% respectively. Rare cases like “rhino-
oto-cereberal” form of mucormycosis, angiomyoma, and psammomatoid ossifying
fibroma were also observed in the study.
Conclusion
Most of the nasal polyps/fungal sinusitis can be diagnosed clinically. However many a
times Computer tomography (CT) scan and biopsy are necessary to differentiate them
from each other and treatment plan. Certain benign tumors have high potential for
malignant transformation while others can present with locally destructive features
and deformities.
