Abstract
Fine needle aspiration cytology is a fast and easy method for diagnosing
any accessible lesion. The majority of head and neck mass are usually superficial and
easily accessible to needle biopsy. The study was undertaken to evaluate the
diagnostic accuracy of FNAC in palpable lesions of head and neck along with an
analysis of age, sex, anatomical site of distribution and histopathological correlation.
It was an institution based descriptive study with cross-sectional design. The study
was conducted in the Department of Pathology, Bankura Sammilani Medical College,
Bankura, West Bengal. A total of 3670 patients were included in the study. A brief
history and physical examination was taken from the patients. FNAC smears were
stained with Leishman-Geimsa and Papaniculaou stain. Zeihl-Neelsen stain was done
in suspected cases of tuberculosis. Surgically excised specimens were available in 142
cases, which were processed and stained with Hematoxylin and Eosin stain. Majority
age group was 21-40 years and male to female ratio was 1ː 1.2. The site of lesion were
distributed according –Lymphnode (46.83%), Thyroid (30.5%), Salivary glands
(6.64%), and Miscellaneous (16.02%). Histopathological correlation was done in 142
cases and overall accuracy rate of FNAC was 90.14% with sensitivity of 92.8% and
specificity of 86.66%. Positive predictive value and negative predictive value were
90.47% and 89.65% respectively. Palpable lesions of head and neck are readily
accessible for FNAC, which aid in our diagnosis and hence proper treatment and
management of the patient. Supplementation by a histological diagnosis often comes
as an additional boon especially in suspicious and malignant cases.
