What are the differences between moles and spots? Introduction to the differences between moles and spots

Moles and spots are two common skin problems. Whether it is a mole or a spot, it will have a great impact on a person's appearance. Many people who love beauty will remove them through medical methods. However, since moles and spots are quite similar, many people cannot distinguish between the two. In fact, there are certain differences between moles and spots. Below I will introduce the differences between the two in detail.

Introduction to moles

Mole is the most common benign skin tumor in humans and is a skin manifestation caused by an increase in the number of melanocytes. Depending on the location of nevus cells in the skin, they can be divided into junctional nevus, mixed nevus and intradermal nevus. Junctional nevus are characterized by being flat and deposited between the dermis and epidermis, intradermal nevus are characterized by being papilloma-like, hemispherical and with melanin deposited in the dermis, and mixed nevus are characterized by being slightly elevated and having both of the above properties.

Moles can occur on the skin and mucous membranes of any part of the body and can be either congenital or acquired. It is in the form of flat or slightly raised macules or maculopapules, or may be hemispherical, papilloma-like or pedunculated, with a smooth surface, with or without hair, and may be single, a few, or dozens in number. Due to the different types and contents of pigments in nevus cells, nevus can be brown, brown, blue-black, black or dark brown. Non-pigmented nevus are mostly skin-colored.

Spots are generally caused by different physical constitutions or by some inducing factors of the human body (such as ultraviolet rays, endocrine disorders, etc.). The essence of spots is that the human melanin gene mutates or is damaged, causing melanin to be deposited in the basal layer of the skin. The spots vary in shape and size and there are many types. In comparison, moles are darker and protrude from the skin, while spots are lighter and paler in color.

The difference between moles and spots

The difference between the two is that moles only pose a risk to skin safety, while spots are a manifestation of skin disease or even physical disease.

Facial pigmentation refers to spots that are different in color from the surrounding areas. Facial pigmentation is a common facial brown or black pigmentation and disfiguring skin disease caused by an increase in skin melanin. It often occurs on the cheeks and forehead and worsens after sun exposure. It is more common in women and is related to pregnancy.

It is related to the menstrual disorders caused by long-term oral contraceptives, which belong to the dark spots and liver spots in traditional Chinese medicine.

Moles can be divided into broad and narrow meanings. The broad meaning includes various congenital and acquired melanocytic nevi, sebaceous nevi, etc. The term "mole" in medicine is used in a narrow sense, also known as nevus cell nevus, pigmented nevus, melanocytic nevus or common acquired melanocytic nevus, and does not include congenital melanocytic nevus. Mole is the most common benign skin tumor in humans. It is a skin manifestation caused by an increase in melanocytes in the epidermis and dermis.
