Desmoplastic trichilemmoma.
Is there suggestion of ducal differentiation in image 6? Acc to kazakov, this is a rarely described feature of trichilemmoma, particularly desmoplastic variant.

The immunoprofile would suggest BCC, but difficult to reconcile morphological findings with BCC i.e. no retraction, stromal mucin and bland cytology plus a clearly thickened basement membrane.
Would probably still stick with desmoplastic trichilemmoma…but waiting to be educated!

The immunos will make it BCC, the surface is ulcerated and there is focal stromal retraction. The centre is morpheaform or sclerotic BCC.
