Histomorphological Variants of Squamous Cell Carcinoma in Upper Aero-digestive Tract
Background: To determine the site wise frequency
of squamous cell carcinoma variants in upper aerodigestive
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
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
Conclusions: Majority of cases of squamous cell
carcinomas in upper aero-digestive tract revealed
classical pattern .
