Moles are benign skin tumors formed by the aggregation of melanocytes. In fact, moles can appear in all parts of the body, and they can appear on the face, trunk and other parts of the body, as well as on the genital area. There is no special reason for the appearance of moles in the genital area. Sometimes patients have moles in the local area, which may be caused by heredity, changes in their own hormone levels, or trauma. For example, if a patient accidentally breaks the skin of the penis, a mole may be formed, which is a relatively common clinical situation. In fact, most of the moles in the genital area are junctional moles, and the probability of junctional moles becoming malignant is relatively low, so close observation is all that is needed.
