HistologyThis section has been translated automatically.
Sharply defined epithelial node, which is bounded laterally and sometimes in depth by normal surface epithelium, but can also penetrate the entire epithelial ligament vertically. The tumor node is overlaid by a strong orthokeratotic corneal layer, which can be crossed by parakeratotic strips. The irregular acantholysis is conspicuous, which can run through the entire tumor parenchyma. Detection of dyskeratoses and also pathological mitoses. The dermis shows an uncharacteristic lympho-histiocytic infiltrate. The mitosis rate is significantly increased focally (see figure). This phenomenon is not so much considered a real proliferation but a "degenerative polymorphism". Lympho-histiocytic infiltrate in the dermis.
