Cytological/histopathological diagnosis correlation.

Cytopathological categorization	Number of cases where surgical specimens were received ()	Percent of the category	Histopathological diagnosis	Number of cases
ND/UNS; ()	2	12.5	Nodular goiter	2
Benign; ()			Nodular goiter	18
	23	12.8	Follicular adenoma	2
			Papillary thyroid carcinoma	3
AUS/FLUS; ()	1	9	Papillary thyroid carcinoma	1
FN/SFN; ()	4		Follicular adenoma	3
		80	Papillary thyroid carcinoma	1
SFM; ()	6		Lymphocytic thyroiditis	2
		75	Papillary thyroid carcinoma	3
			Follicular adenoma	1
Malignant; ()	4	80	Papillary thyroid carcinoma	4

(1) ND/UNS = nondiagnostic/unsatisfactory, AUS/FLUS = atypia of undetermined significance/follicular lesion of undetermined significance, FN/SFN = follicular neoplasm/suspected for a follicular neoplasm, and SFM = suspected for malignancy.
(2) = total number of cases.
