The tumor consists of malignant cells, corresponding to the keratinocytes of the spinous layer of the epidermis: eosinophilic cytoplasm, intercellular bridges, focal keratinisation (in differentiated tumors).
Tumorous cells are polymorphous, there is (often high) mitotic activity, focal necroses, infiltrative growth. Horn pearls are the sign of good differentiation. Sometimes acantholysis is present.
