Tissue Expression of Low and High Molecular Weight Cytokeratins in Lung Carcinoma Sections: Its Correlation with Some Clinic-Pathological Features

Table 3

Expression of both high and low molecular weight cytokeratins according to histopathological type.

Tissue samples	Number of cases	^a34βE12 + ^b35BH11
Low/high expression (%)		−	+
Epidermoid carcinoma	16	56.3	43.7
Adenocarcinoma	20	80.0	20.0
Large cell carcinoma	10	50.0	50.0
Other	6	66.7	33.3
Small cell carcinoma	16	100	0

^a34βE12 reacts with high molecular weight cytokeratins (1, 5, 10, and 14); ^b35BH11 stains cytokeratin 8 (low molecular weight cytokeratin).
