Description: The convex armor: the central part of the nail surface is obviously raised above the circumference, and the end of the nail is drooping, like a shell or an inverted spoon. There is a slight concave point on the surface of the light observation, and the color of the nail is slightly white. Trace color powder, abnormal respiratory system, caused by liver disease. Then it is due to lack of calcium, or zinc, which should be nutritional deficiency. In some cases, it is also abnormal with congenital nail development, malformation, or nail bed or nail due to traumatic injury, resulting in abnormal nail growth and abnormal convexity. Symptoms, as well as fungal infections of nails, etc.
The cause of the convex armor: no data available. However, the convex nail is prone to tuberculosis.

The diagnosis of the convex armor: the central part of the nail surface is obviously raised above the circumference, and the end of the nail is drooping, like a shell or an inverted spoon. There is a slight concave point on the surface of the light, and the color of the nail is slightly white. Trace color powder.
Differential diagnosis of convex nails:
(1) Nail protrusion
There are protrusions on the smooth nails, and the shape of the protrusions varies, indicating that there are different lesions. However, in general, the convex change indicates that there is chronic inflammation in the body, and the compensatory pathological changes such as hyperplasia and hypertrophy of the tissues and organs.
1. The rib has a raised stripe on the nail, indicating that there is chronic inflammation in a certain body of the body.
2. Intermittent convex deformation on the chain-shaped nails is connected into a chain, which is called a chain-like change. Inflammation of a certain organ has been shown to have a recurring attack.
3. Comma-like nails have a little or a few convex changes, and the shape is like "," called a comma-like change. It indicates that there is an acute small focal lesion in the tissues and organs of the body. When one lesion improves and another lesion appears again, the comma changes appear one after another.
4. Lateral convex nails appear horizontal or horizontal arc-shaped bulge changes, one or two rafts are wavy, called transverse convex. It indicates that there are large lesions in the body. With the different nutritional conditions, treatment and rest of the body, the condition changes from bad to bad.
(two) nail concave deformation
The morphological changes of streaks, spots, blocks, spots, etc. on the nails are collectively referred to as concave changes. The concave deformation shows the pathological changes of a certain organ and organ function, destruction of tissue structure, atrophy and the like. In short, it reflects the pathological changes of limp.
1. The large arc-shaped concave deformation is about 1/2 of the nail, and there is a horizontal arc-shaped depression in the central part of the nail, which is called a large arc-shaped concave deformation. It indicates that an organ has serious damage, and the compensatory function cannot compensate for the damage function, and the development of the disease and the reduction of function exist simultaneously. Such as rheumatic heart disease, repeated episodes of cholecystitis, gallstones, uterine prolapse, rheumatoid arthritis, severe anemia.
2. Large irregularities on the nails, such as the use of a knife to dig a piece or a few pieces of varying sizes and different shapes. Two nails have large irregular irregularities at the same time, indicating that chronic diseases have turned into malignant changes. Such as cancerous sinusitis, cancer of cervicitis. Appearing on a finger often indicates acute rheumatic heart disease.
3. The transverse shape is a horizontal depression in the center of the nail, as caused by extrusion. It is closely related to rheumatism, such as rheumatic myocarditis. The condition is relatively mild.
