What are papules?

Papules are localized protrusions above the skin, which may be as small as a needle tip or as large as a soybean. They may be elevated or flat, smooth or warty in structure, or have pigmentation the same as the surrounding skin (those with a diameter of more than 1 cm are called plaques). Many skin diseases begin with lesions from papules, which should be closely observed and diagnosed.

Causes of papules

Various skin diseases can present as papules. Some cases only present with papules, while others are accompanied by other skin lesions. The lesions of papules are located in the epidermis or upper dermis. Therefore, from a pathological point of view, the mechanism causing papules is the accumulation of certain metabolic products in this area; or localized proliferation of epidermal or dermal cells; or inflammatory edema and infiltration of various cells in this area can all manifest as papules.

Deposition of metabolic products: For example, the papules of skin amyloidosis are caused by the deposition of amyloid protein in the dermal papillae. The papules with new fluid-like edema and lichenification are caused by the deposition of large amounts of alkaline protein in the upper dermis.

The papules of colloid miliary papules are caused by infiltration of homogeneous colloid masses in the papillary dermis.

Papules caused by localized proliferation of epidermal or dermal cells, such as common warts, flat warts, and psoriasis, are all caused by excessive proliferation of epidermal cells resulting in localized protrusions of the epidermis. German and dermatofibromas are also papules formed by proliferating cells.

Through the above introduction, we have a good understanding of what papules are. When treating such diseases, it is also necessary to do it in a timely manner. However, when treating such diseases, we must pay attention to the choice of methods.
