The best answer was chosen by the questioner/end time: 2006-07-16 13:28:58 vera_myy [Situ] reported that corns are conical cuticle thickening caused by long-term friction and pressure. The horny central core has its tip deep into the skin and its base exposed to the outside. It is more common in young people and is more likely to occur on the soles of the feet and toes. If the tip of the corn presses the nerve endings, you will feel pain when walking. Treatment: Laser cauterization can be performed in the hospital during treatment. If all treatments are ineffective, corn removal may be performed. Prevention: To prevent corns, you must first correct foot deformities and wear loose, appropriately sized shoes to reduce local friction and compression. Alias ??Pathology Overview Corns are conical corn-like keratinous growths on the soles or toes that occur due to long-term extrusion or friction. For the treatment of popular characteristics and pathogenesis, it is recommended to soak the affected area with hot water first, peel off the surface cuticle, protect the surrounding area and expose the corns, and then apply various strong cuticle exfoliants externally, such as commercially available corn ointment, 15-salidate lactocin ointment. 0.3 tretinoin ointment, 10% silver nitrate solution, etc., repeat every few days until the tip is dug out. If the corn is not infected, it can be removed by excision. This method usually uses a pointed scalpel to make a circular incision along the edge of the horny hypertrophy, clamp it with toothed tweezers, peel it off on top of the zona pellucida, and dig out the corn. It is painless to walk immediately after digging it out, and it can be pain-free and hair-free for at least 2 months. If it recurs, it can be dug again, usually 1-2 times, and sometimes 5-6 times can be cured. The above excavation method can be combined with external application method for combined treatment. Prevention: Wear suitable and soft boots or shoes, or use small pieces of perforated sponge pads to protect the area from pressure. Clinical manifestations: Corns are cone-shaped keratin plugs embedded in the skin. They are generally from the size of a needle to a soybean or larger. The surface is smooth and flat with the skin surface or slightly raised. It is light yellow or dark yellow and translucent. The tip of the cone extends into the skin and is wedge-shaped. The flat bottom surface is exposed outside the skin. If the horny material on the surface is peeled off with force, a hard needle-like horny plug can be seen in the center, and there is a transparent light yellow ring around the outside. Corn-shaped. Most of them are 1-2, and occasionally there are multiple cases, which are generally not easy to heal on their own, if the causative factors are removed. It can also disappear naturally. Corns can be hard or soft. Hard corns commonly occur on the soles of the feet and the outside of the little toe, on the back of the toes and other areas where bones are protruding or prone to pressure and friction, and are round or oval in shape. The surface is flat, hard, and light yellow in color. Its tip can reach as deep as the papillary layer of the skin. When standing or walking, it often causes severe pain due to compression of the sensory nerve endings in the papillary layer, making walking difficult. Soft corns often occur on one toe between two adjacent toes. They are soaked due to moisture and become grayish white with a foul odor. It is diagnosed as occurring in areas subject to frequent friction and pressure, such as the soles of the feet or between the toes. The lesions are bean-sized or larger, slightly yellowish cone-shaped keratin plugs, with the base facing outward, slightly above the skin surface, and a wedge-shaped tip embedded in the dermis. There is pain when walking, and the corns between the toes often soak and become soft, and need to be differentiated from plantar warts; plantar warts are distributed throughout the soles of the feet, not limited to the pressured parts, there can be more than one, and they are soybean-sized horny Thickening and peeling off the surface cornified layer can reveal the cross-section of the epidermal spinous process and the upper end of the dermal papilla and the small black dots of soft keratin that are condensed with the trace amounts of blood exuded from the dermal papilla blood vessels, with a keratin ring outside. Plantar warts occur due to viral infection. Differential Diagnosis Complications Causes It is more likely to occur in people who walk frequently or stand for long periods of time, and is often related to occupation. The important predisposing factors are local friction and external pressure, such as wearing uncomfortable boots and shoes. The feet are stimulated and rubbed for a long time, so the disease often occurs in both feet at the same time, and it is more common in thin young adults. It is often accompanied by chronic keratotic and desquamative tinea pedis. Grubs can cure corns. First, break through the old white skin, smash the grubs (larvae of scarab beetles, some are called earthworms, soilworms, walnutworms, etc. in different regions), and stick an adhesive tape on the affected area. If you have corns on your feet, here are some methods you can try to get rid of them. 1. Take 10 black plums, grind them into fine powder, put them in a bottle, add sesame oil and soak them for 7 to 10 days, and mix them into an ointment. Soak the corns in warm salt water, remove the rough skin after it softens, apply an appropriate amount of ointment on the corns, then wrap it with gauze, change the dressing every 12 hours, and a course of treatment is 3 days. 2. Take 10 grams each of Digupi and safflower, grind them into fine powder, add appropriate amount of sesame oil to make a paste.

After soaking your feet in hot water every night, apply an appropriate amount of medicine paste on the corns, then cover it with a non-toxic plastic film and secure it with tape. 3. Take aloe vera and a little salt water and grind it into a paste. After soaking your feet in hot water every night, apply an appropriate amount of medicine paste on the corns, cover them with non-toxic plastic film, and then fix them with tape. Once a day, 10 days is a course of treatment. 4. Take one purple-skinned single-headed garlic, one white scallion, and 3 to 5 peppercorns, mix them together into a paste, apply them on the corns, and seal them with tape. Remove the tape and mud after 24 hours. If it is not healed after the first treatment, it can be used again. 5. Take more than 10 Liushen Pills, grind them into fine powder, add appropriate amount of vinegar to make a paste. Wash the corns, remove the surface cuticle, soak in salt water for half an hour, apply the medicine paste on the corns, and fix it with tape. Change the medicine every 3 days. 6. Take a few aspirin tablets and mix them with salt water into a paste, then apply it on the corns and apply it with a hot towel for 10 minutes. Once a day, 1 week is a course of treatment. When using the above method to soften corns, if damage, bleeding, or pus occurs, you should go to the hospital for treatment in time to avoid delaying the condition.
