Background: Early and accurate pathological diagnosis of skin cancers is vital. FNAC supposedly gives satisfactory

results in diagnosis of nodular skin & subcutaneous lesions.

Objective: To analyse the incidence of cutaneous/subcutaneous lesions by FNAC and to study the accuracy of cytological diagnosis against

histopathological diagnosis.

Methodology: In this cross-sectional study, 777 cases of clinically suspected nodular skin & subcutaneous lesions were studied by FNAC

and 381 cases were additionally diagnosed histologically.

Observations: Non-neoplastic lesions (45.03%) contributed the most, followed by benign (39.6%) and malignant tumours (15.37%). Total

377 out of 381 cases showed good correlation between cytology and histopathology (diagnostic accuracy-98.95%). The sensitivity,

speci􀃶city, positive predictive value and negative predictive value of FNAC in the diagnosis of malignancy were calculated to be 100%,

99.48%, 97.61% and 100% respectively.

Conclusion: Cytodiagnosis by FNAC is a reliable screening technique in the evaluation of cutaneous and subcutaneous lesions.
