Palate Squamous Cell Carcinoma (SCC). A. Basaloid SCC, neoplastic proliferation consisting of invasive solid, trabecular, cords, and nests tumor proliferations that sometimes present obvious peripheral palisading. HE staining, x100; B. Acantholytic SCC, with islands and sheets of neoplastic squamous cell carcinoma with central prominent acantholysis that create a false appearance of glandular differentiation. HE staining, x50; C. SCC invading the palate bone. HE staining, x50; D. Moderate- differentiated SCC invasive in muscle fibers. HE staining, x100; E. Lymph node with SCC metastasis. HE staining, x25; F. SCC invading nerve bundles. HE staining, x200
