Morphological Cell Type Analysis of Schneiderian Papillomas. A Two Year Study At Tertiary Care Hospital.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 9
Abstract
Background and objectives: Schneiderian papillomas are benign neoplasms accounting for 0.4 to 4.7% of all sinonasal tumors. They have three main characteristics such as capacity for local destruction, tendency to recur and association with squamous cell carcinoma. They are classified into inverting, fungiform, and oncocytic. These should be distinguished from one another histopathologically. This study highlights the histopathological differences between the Schneiderian papilloma subtypes and papillomas with malignant transformation. Methods: This study was a descriptive study done in Department of Pathology, Stanley Medical College, Chennai, India for a duration of 2 years from 2013 to 2014. During the study period 10 cases of formalin fixed (10%), surgically resected sinonasal papillomas were received from ENT Department Stanley Medical College. They were processed and slides were prepared for histopathological diagnosis. The stained cytological and histopathological slides were studied, analyzed and correlated. Results: The histopathological features were studied and analyzed and the following observations were made: Out of 10 cases 4 cases fall between 3rd to 4th decade, 4 cases between 4th to 5th decade and 2 cases in the 7th decade. All were males and all 10 cases were in sinonasal region. Most common lining epithelium was squamous epithelium (4 out of 10). Least common was oncocytic (1out of 10). Malignant transformation was seen in 2 cases. Conclusion: Sinonasal papillomas are benign epithelial neoplasms arising from Schneiderian mucosa. Although the incidence of inverted papilloma is much higher compared with the other papilloma subtypes, exophytic and oncocytic papillomas must be recognized and differentiated
