Histomorphological Variants of Squamous Cell Carcinoma in Upper Aero-digestive Tract

Abstract

Background: To determine the site wise frequency
of squamous cell carcinoma variants in upper aerodigestive
tract.
Methods: In this observational study all the cases
of diagnosed squamous cell carcinoma of upper aero
digestive tract were included. All the cases were
formalin fixed and processed routinely to form
paraffin blocks. Slides were made and stained with
H&E.
Results: Out of 41 cases, 33 cases showed the classic
pattern of squamous cell carcinoma, which arose
from Oral cavity, alveolar ridge, tongue, oesophagus,
palate, pharynx, nose, larynx and bronchus. Most of
the classic squamous cell carcinomas were of
keratinizing type.
Conclusions: Majority of cases of squamous cell
carcinomas in upper aero-digestive tract revealed
classical pattern .
