Giant mole

Introduction Giant scorpion disease, the corpus callosum is located in the trunk and limbs, and the area is more than 900CM2. The diagnostic criteria for pythons vary depending on the age of the patient and the location of the disease. For pigmented sputum in specific parts such as forehead and face, although the area is less than the above criteria, the wound can not be directly sutured after surgical resection, and can also be regarded as giant python. Giant pythons exist at birth, often infringe on many parts, the surface is often uneven, rough and fat, and hair is often found. Giant pythons are mixed sputum or intradermal sputum, so there is also the possibility of turning into malignant melanoma.

Cause

The etiology of megalin is still unclear. The literature reports are related to genes, but its genetic form is still unclear. Some scholars believe that it is a variant expression of an autosomal dominant gene, but it lacks a comparison of the normal population, but only one of the identical twins has a giant scorpion, which negates the above viewpoint. Therefore, some people think that very chromosomal dominant inheritance is also not recessive, and there is no evidence of genetic inheritance. Some scholars believe that it is multi-factor inheritance, and some scholars have found that the placenta of the giant scorpion fetus also has a huge melanin lesion, and that the giant scorpion is caused by the filtration of sputum cells in the fetal blood circulation.

Giant sputum

Differential diagnosis

Combined

It is formed later, generally flatter, and the sputum cells are at the junction of the epidermis and the dermis. The number of cells is large and the activity is strong, which is more susceptible to malignant changes.

Compound

The acquired sputum will change from the original flat to a slightly protruding hemisphere over time, and the surface will be smooth. As it grows deeper into the upper dermis, the color will change to skin color or brownish black, and the activity of black cells is reduced, malignant. The probability of change is also low.

Pinet

It evolved from a complex sputum, and the sputum cells grow downwards, completely detached from the epidermis, and are clinically convex, brown to flesh-colored.
