The first immuno shown yesterday was BerEP4.

The other immunos showed:

CD56 and chromogranin patchy positive, whereas negative staining for EMA, synaptophysin, CK20, TTF-1, CK7. Cam5.2 weak patchy membranous only.

This is a nice example of BCC with neuroendocrine differentation, with more typical BCC highlighted at the periphery, more 'high grade' centrally. The limited literature indicates that BCC with neuroendocrine differentation has an excellent prognosis i.e. no metastatic potential.
