Pseudo-acanthosis

After 14 hours, the epidermal lesions are significant in certain places the epidermal cells are extremely swollen (pseudo-acanthosis ), elsewhere we see an atrophy of the epidermis and next to it, either a pseudo-acanthosis, or an acanthosis. Intra-epidermal vesicles are frequently seen (Fig. 20). 

Pseudo-acanthosis — thickening of the epidermis not due to the increase of cellular layers but to their swelling.
