Final answer:
The skin disease caused by increased mitotic division of epidermal cells is psoriasis, characterized by rapid cell turnover leading to thick, inflamed patches of skin with silvery scales.
Step-by-step explanation:
The chronic and sometimes acute relapsing skin disease caused by increased mitotic division of epidermal cells is known as psoriasis. Psoriasis is characterized by the rapid turnover of skin cells, leading to thick, red, inflamed patches covered with silvery scales. This skin disorder can appear on various parts of the body such as the elbows, knees, scalp, back, face, palms, and feet. Cell turnover that normally takes a month occurs in just a few days due to cytokine activation. This rapid rise of skin cells to the surface is what causes the noticeable symptoms of psoriasis.
