The purpose of the present study was to identify the expression particularities of analyzed E-cadherin in rapport compediu the localization and the differentiation of various head and neck squamocellular carcinomas.
Immunoreactions for E-cadherin in the tumoral cells were examined according to ocmpendiu score: The immunohistochemical staining indicated the presence of 12 cases of well-differentiated squamocellular carcinoma 7 cases with score 3, 3 cases with score 2 and 1 case with score 1. Moderately-differentiated carcinomas were observed in the 3 cases 2 with score 2 and 1 with score 1.
The poorly-differentiated histopathological type was present in 3 cases all with score 1.
Three types of E-cadherin distribution patterns were found: The presence of maximum score value 3 of E-cadherin was found in well-differentiated vaciala carcinomas of laryngeal, tongue, lip, nasal pyramid, and zygomatic area origin. A lower value of the score was present in the less differentiated histopathological type.
