The correct choice is psoriasis, which is characterized by epidermal hyperplasia and increased turnover. In psoriasis, the normal process of skin cell turnover is accelerated, leading to a buildup of keratinocytes in the epidermis. This results in thickened patches of skin, known as plaques, which are often red with silvery scales. The rapid proliferation of skin cells occurs due to a combination of genetic and immunological factors, making the condition distinct.

Epidermal hyperplasia is specifically evident in the stratum corneum, where the excessive production and retention of cells leads to the formation of the characteristic plaques associated with psoriasis. Increased turnover rate not only contributes to the scaling and thickness of the plaques but also plays a key role in the inflammatory process seen in this autoimmune condition.

Other skin conditions may involve dysregulation in skin turnover or inflammation, but their mechanisms differ from those seen in psoriasis. For instance, atopic dermatitis is typically characterized by a reduction in the barrier function of the skin and not a marked increase in cell turnover. Tinea corporis is a superficial fungal infection presenting with scaling and erythema but does not involve significant epidermal hyperplasia. Ecthyma, a deeper skin infection often resulting from bacteria, causes ulcerative
