ABSTRACT
OBJECTIVE:
This article aimed to study two different parameters of basal cell carcinoma (BCC) First, to analyze the expression of antihuman epithelial antigen (Ber-EP4) on the primary and recurrent BCCs on the head, neck, and other body parts and second, to find Ber-EP4's staining pattern and staining intensities correlation between histological type, demographic data, tumor, and its prognostic parameters.METHODS:
We evaluated the Ber-EP4 staining patterns of 201 patients diagnosed with BCC. We analyzed the possible correlation between the tumor's prognostic parameters and the Ber-EP4 staining intensity and its pattern (peripheral, superficial, or diffused).RESULTS:
In 199 out of the 201 cases, staining was observed. Two cases were unstained. In 25.6% (n=51) of the cases with staining, the staining was weak, on the 25.6% (n=51), it was moderate, and on the 48.8% (n=97), it was severe. The staining pattern was 31.2% (n=62) peripheral, 4.0% (n=8) superficial, 54.7% (n=109) diffuse, and 10.1% (n=20) peripheral and superficial.CONCLUSION:
Ber-EP4 is the only antibody commonly used for BCC diagnosis; the existence of different staining intensities and patterns in BCC tumor cells in routine dermatopathology practice limit the pathologists. The studies investigating Ber-EP4 staining in BCCs were conducted with very small numbers of cases. In these studies, even the presence of staining in the focal area was considered to be a positive acceptance criterion; the staining intensity and pattern were not evaluated. Therefore, our study is the first study with a high number of cases and the first to include an evaluation of Ber-EP4 staining's intensity and localization.
