Mixed mole

Mixed introduction Mixed : Appearance is similar to the border , more common in teenagers, sometimes hair grows. The pathological changes of mixed sputum are characterized by both border sputum and intradermal sputum. The sputum cell group is found in the dermis or in the epidermis, and the lower part of the sputum cell can be fusiform, buried in the collagen tissue, with little or no Contains melanin. There is little or no inflammation in the dermis. Most of the skin lesions are slightly higher than the leather surface, some are papillary, the color is yellowish brown to brown, and the surface may or may not have hair. itself has little effect on health, it can not be treated, and it is often considered because of cosmetic needs or malignant changes. Currently commonly used treatment methods include surgical resection, chemical drug corrosion therapy, laser therapy and liquid nitrogen freezing, ionization, microwave and electrocautery. basic knowledge The proportion of sickness: 0.1% - 0.25% Susceptible people: no specific population Mode of infection: non-infectious Complications: skin cancer

Mixed sputum

Cause:

Can be caused by a variety of reasons, no final conclusion. It is generally believed that the occurrence of mixed mites is related to genetic factors and environmental factors dominated by ultraviolet light.

pathology:

It is composed of sputum cells, which are characterized by the arrangement of sputum cells into nests. Typical sputum cells are oval or cuboid, with obvious homogenous cytoplasm, large nucleus, round or oval, pale and lightly stained, and vesicular. Because the life cycle of sputum cells usually undergoes different stages of development, maturation and aging, and gradually moves from the epidermis to the dermis with age, the morphology of sputum cells in different parts of the skin is different. The sputum cells in the upper part of the dermis are epithelial-like, often containing melanin. The sputum cells in the middle of the dermis are similar to lymphoid cells, while the sputum cells in the lower part of the dermis are similar to fibroblasts or Schwann cells. Less melanin. The sputum cell nest is found in the epidermis and in the dermis. The upper part of the dermis is cuboidal, rich in cytoplasm, and contains many different melanin particles. In the middle of the dermis, the sputum cells are smaller, the cytoplasm is less, and the melanin is less, usually nested, and the boundary is clear.

Mixed cockroach prevention

In addition to aesthetic factors, in order to avoid becoming a malignant melanoma, the following cockroaches should be removed:

1. It will be stimulated by long-term friction, such as wearing a bra and waist.

2. The embarrassment of atypical changes. Atypical sputum may become malignant, such as very dark sputum, uneven pigmentation (mosquito), uneven or irregular edges, unclear boundaries, left and right asymmetry, and statistically larger than 5 mm in diameter.

3. A single cockroach suddenly changes rapidly. If the whole body is changing at the same time because of the change of hormones, it is more undoubted. If it is a single sudden change, it is worth noting.

4. The dragonfly grows in a special part. If you are on the extremities (hands and feet), you must pay attention to observation, because the sputum in these places has a greater chance of becoming malignant melanoma than other places.

5, the mucosal sputum. The part of the oral mucosa, conjunctiva, vagina, and foreskin turned out.

6, the nail sputum. The nail groove is connected to the skin under the nail, and may grow under the nail and be blocked by the nail. It is not easy to see the change, and it grows on the extremity, and the chance of becoming malignant is greater in the future.

Mixed sputum complications Complications skin cancer

Can be infected concurrently. Most of the growth is slow, or has not changed for many years, but rarely spontaneously degenerate. There is also the possibility of turning into a vicious one, thus endangering life.

Mixed sputum symptoms Common symptoms Skin phlegm, local burning, itching, skin bleeding, severe pain

Mixed sputum is a sputum cell nest located in the epidermis and dermis, slightly uplifted or papillary, with a malignant tendency, such as: sudden darkening of the pigmented nevus, enlargement, local mild itching, burning or pain, surface hair loss, ulceration, bleeding or The phenomenon of inflammation, as well as the appearance of satellites at the edge, are mostly signs of malignant transformation.

Mixed helium inspection

an examination:

1. Physical examination of general skin diseases.

2, when there is a tendency to malignant, do a pathological biopsy.

Mixed diagnosis

diagnosis

It can be diagnosed through clinical diagnosis, and pathological examination is performed in patients with suspected malignant transformation.

Differential diagnosis

Different from diseases with pigmented skin lesions, such as senile dark spots: occur in the exposed parts of the middle-aged and elderly, such as the cheeks, neck, back of the hands and forearms, mostly scattered in tan, the size of the area is not A small round, elliptical or irregular shape that is smooth or slightly higher than the plaque of the leather surface. Histological examination showed that normal melanocytes increased and no malignant changes occurred.
