If there are particles within the skin of the labia and itching can occur, it may be related to the following reasons: First, if the particles are relatively large and appear as cauliflower-like redundancies, and the surface is not smooth, it may be due to acromegaly caused by low-risk HPV virus infection, which is mainly transmitted through sexual contact in clinical practice with a history of high-risk sexual life. Second, because the vagina itself has a chronic inflammation, the infection time is relatively long, the skin of the labia under the stimulation of chronic inflammation leads to tissue proliferation, so there will be relatively small superfluous, but also itchy situation. It is recommended to actively treat vaginal inflammation and the itching will be relieved, but the particles tend not to disappear. It is recommended to keep local cleanliness in daily life and actively treat the inflammation if it is present.
