Malignant epithelial tumor showing keratinization and intercellular bridges. Evidence of local origin is lacking. I favor metastatic squamous cell carcinoma from primary site in the oral cavity.

Agree, SCC x Melanoma. Less probably Sebaceous carcinoma, I would include adipophilin in my IHQ pannel.

looks like an SCC to me. Sebaceous Carcinoma would certainly be a consideration given the focal suggestion of sebaceous differentiation particularly in 2nd image from the bottom (right)

SCC probably follicular variant (acantholytic). Individual tricholemmal cell keratinisation. The lack of bowenoid change it typical of this common variant but need to see the nice infundibular connections so only a provisional diagnosis at this stage. You could see if there is follicular mucin with alcian blue. Many of our cases are p53 null or diffuse, p16 neg.
