To distinguish trichoepithelioma and trichoblastoma with BCC requires the use of other immunohistochemistry test using pleckstrin homology-like domain (PHLDA1), whereas a panel of BerEP4, cytokeratin (CK) 14, and CK17 is needed to reliably differentiate BCC and BSCs from bSCCs [10, 24, 34, 35]. Here, PLEK is linked to trichoblastoma.
