What does the beard on the mole represent?

It doesn't make any sense. This seems to be a lot, just like long hair on the skin.

Nevus can be divided into broad sense and narrow sense, and the broad sense includes all kinds of congenital and acquired melanocyte nevus and sebaceous nevus. Medical "nevus" is a narrow sense, also known as nevus cell nevus, pigmented nevus, melanocyte nevus or common acquired melanocyte nevus, excluding congenital melanocyte nevus.

Nevus is the most common benign skin tumor in human beings, which is the skin manifestation caused by the increase of melanocytes in epidermis and dermis. According to the different positions of nevus cells in the skin, it can be divided into borderline nevus, mixed nevus and intradermal nevus. The flat lesions suggest borderline nevus, and the slightly higher lesions are mostly mixed nevus, while papilloma-like lesions and almost all hemispherical pedicled lesions are intradermal nevus.

differential diagnosis

Differentiate from diseases with pigmentary lesions, such as senile black spots: it is more common in exposed parts of middle-aged and elderly people, such as cheeks, neck, back of hand, forearm, etc., and it is mostly brown, small round, oval or irregularly smooth or slightly higher than the skin surface. Histological examination showed that normal melanocytes increased without malignant transformation.

complication

It will be complicated with infection. Most of them grow slowly, or remain unchanged for many years, but spontaneous degradation rarely occurs. Individual types of moles may also become malignant, thus endangering life safety.
