EPCAM and skin neoplasm: Further research using BerEP4 immunohistochemistry consistently gave similar results; the study by Dasgeb et al. (2013) using BerEP4 to distinguish 24 BCC specimens with 88 common skin neoplasms, namely, trichoepithelioma, actinic keratosis, squamous cell carcinoma in situ, squamous cell carcinoma, seborrheic keratosis, lichen planus like keratosis, nevi, hemangioma, inverted follicular keratosis, sebaceous adenoma, and Merkel cell carcinoma (MCC) from dermatopathology files, also showed that it was able to diffusely stain all BCC sections.
