Fortune-telling of lacrimal caruncle _ the theory of nevus of lacrimal caruncle

Many small moles have grown on the face. What method can make it? ...

Moles can exist in any part of the body except the face. The vast majority of moles are benign and have no harm to physical and mental health, and only a few moles will become malignant. Nevus, medically called pigmented nevus, can appear in any part of the human body except the body surface, and some grow on the nasal cavity, external auditory canal, eyelid margin, lacrimal fossa, oral mucosa and gastrointestinal mucosa surface. Some are as small as the size of a needle tip; Some are so big that the whole body skin is covered with black pigskin, which is called giant mole in medicine. Moles can be colored or colorless; Some moles have hair and some have no hair; Some can be higher than the skin surface, and some are as flat as the skin; Some grow in the skin, and some can reach subcutaneous tissue; Some can be benign for life, and some can be malignant; Some growth sites are exposed, some growth sites are hidden, but more often occur in exposed parts of the body.

According to the statistics of medical experts, there are more than 20 moles on average, and 40% of benign moles occur in the head, face and neck. Pigmented nevus growing on palm, sole, vulva, glans penis, back and face is easy to cause malignant lesions due to frequent friction; In medical literature and medical practice, we can often see and hear that some patients have craniotomy because of brain tumors. After tumor resection, it was found that it was not a primary brain tumor, but a metastatic nevus transferred to the brain due to malignant transformation of melanocyte nevus in the sole of the foot, which could cause hemiplegia, aphasia, strabismus and even death. The moles on the face have various reputations, such as "Beauty Mole", "Blessing Mole" and "Hidden Pearl Yu Mei". Some people think that this is bad for the appearance and ugly, so they often rub and stimulate it artificially, such as picking, pinching, grasping or handling it in an inappropriate way (such as corrosion with chemicals such as calcium carbide, lime water, strong acid and strong alkali, and picking, handling and freezing with a needle). ). Constantly stimulate moles with some irritating substances to cause malignant transformation. The main reason of malignant transformation of nevus is that all nevus cells can not be removed at one time, so that the remaining nevus cells grow and become active. A young lady from Hong Kong has a mole on her right external auditory canal. She often picks with her fingers, which leads to repeated injuries and bleeding of moles. A year later, the nevus keeps growing and festering, which leads to obstruction and infection of the external auditory canal, and often leads to running water, pus and bleeding.

In many hospitals in Hong Kong, due to the narrow anatomical position, the treatment is difficult and the curative effect is not ideal. After being introduced to Shanghai for treatment, he was diagnosed as basal cell carcinoma by pathological examination. Using laser therapy, not only the tumor tissue was removed, but also the normal shape of the external auditory canal was maintained, eliminating the pain of digging the ear with a knife. After a year's observation, the cancer did not recur. There have been more than 30 such cases in recent years, and all of them have received satisfactory results. Even some patients were told to cut their noses, ears and eyelids, but after laser treatment, they removed the lump without disfigurement or knife injury, maintaining normal tissue morphology and normal physiological function.

Because everyone has a mole, is it malignant, whether to treat it or not, and how to treat it? This is a problem that everyone cares about. The medical profession also has different views on this issue. In recent years, the experience of laser treatment of tens of thousands of moles (such as melanotic nevus, common pigmented nevus, blue nevus, halo nevus, palpebral nevus, internal mound nevus, colorless nevus, soft nevus, solar nevus, etc.). ) that is, most moles are benign and generally do not need treatment; Pigmented nevus on the head and face, which is too large and affects the appearance, grows on the edge of eyelid (such as nevus on the edge of eyelid), affects vision or is suspected of malignant transformation, and should be treated; Pigmented nevus on the head, back, palm, sole, genitals and other easily worn parts has a high probability of malignant transformation, so it should be completely removed at an early stage to prevent malignant transformation and metastasis.
