    TLDR The skin has two main layers, the epidermis and dermis, which work together and are essential for diagnosing skin conditions.
    The document discussed the complex histology of the skin, emphasizing its importance for accurate diagnosis in cutaneous pathology. The skin was described as having two main layers, the epidermis and dermis, which are functionally interdependent, along with a closely related subcutaneous adipose tissue. The epidermis primarily consisted of keratinocytes and included other cell types like Langerhans cells and melanocytes. It featured specialized structures such as eccrine sweat ducts and had a complex architecture with retes and dermal papillae. The dermis contained various cells within a collagen and glycosaminoglycan matrix, supporting hair growth and temperature regulation. The subcutis acted as a cushion with lipid-engorged cells and nourishing vessels. Understanding these structures was crucial for recognizing normal and pathological conditions in the skin.
