There is a lump in the middle of the toe

If there is a lump in the middle of the toe, it is most likely a corn. Corns are also called corns. People who stand or walk for a long time are most likely to suffer from corns, which are mainly caused by continuous pressure and friction on the soles of the feet. However, there are several diseases similar to corns that we need to distinguish, such as plantar warts, calluses, etc. Only by understanding the situation clearly can we get better treatment.

The disease is more likely to occur in people who stand or walk for a long time, and friction and pressure are the main causes. Tight shoes or deformed foot bones can cause the stratum corneum in areas of the foot that are subject to friction or pressure to thicken and push inward, forming a cone-shaped keratinous substance with the top facing inward. Clinical manifestations: skin lesions are round or oval localized keratin hyperplasia, ranging in size from a needle tip to a broad bean, light yellow or dark yellow in color, with a smooth surface that is flush with the skin surface or slightly raised, with clear boundaries, and an inverted cone-shaped keratin plug in the center embedded in the dermis. The tip of the keratin plug stimulates the nerve endings in the dermal papilla, causing pain when standing or walking. Corns often occur at the third metatarsal head in the front and middle part of the plantar, on the tibial edge of the metatarsal, and also on the dorsum of the little toe and the second toe, or between the toes, and other protruding and friction-prone areas.

Differential diagnosis of this disease is generally not difficult based on the characteristics of the lesions and the predilection sites. The following should be identified. 1. Plantar warts are not limited to the pressure-bearing areas on the soles of the feet. The surface shows papillary keratin hyperplasia, and there are often black bleeding spots where the skin lines are interrupted. There is obvious pain when squeezing. 2. Calluses are found at the compression points of the soles of the feet. They are irregular keratinized patches or strips with smooth surfaces and unclear edges. They do not cause pain when walking or rubbing. 3. Palmoplantar punctate keratosis: Multiple isolated and cone-shaped keratinous masses on the palms and soles, which are not wedged into the skin and are not limited to the areas of friction.

Treatment 1. External use of corrosive corn plaster or corn ointment, you can also use 10% salicylic acid glacial acetic acid, 30% salicylic acid collodion and crystal cream. Topical corrosive agents must protect the surrounding skin. You can cut a small hole in the center of the zinc oxide tape, the same size as the skin lesion, and stick it on the skin lesion to expose the lesion. Use thin strips of tape to roll into a rope to surround the hole to form a dam. Then apply the medicine and cover it with a large piece of tape. Seal it and change the dressing once every 3 to 7 days until it falls off. 2. Physical therapy: electrocautery, carbon dioxide laser cauterization, contact X-ray irradiation. 3. Surgical resection.
