lump in ear hole
Introduction
Introduction A mass that grows in the ear hole. In medicine, this mass is called "keloid" and is the most special type of scar. A small damage can be caused, it can be increased, and the range of growth can exceed the damage. It is often higher than the surface of the skin, the color is red, and the texture is hard. Therefore, it has another name, "crab foot swelling." There are many reasons for the production of keloids. First of all, it is related to the scar structure of human beings. This type of person's chest - the neck, upper arm and other parts are prone to obvious scars. Secondly, it is related to the operation. And the nickel needles used in the ear holes or some of the metal earrings themselves, produce local contact dermatitis, which promotes the production of keloids.
Cause
Cause
There are many reasons for the production of keloids. First of all, it is related to the scar structure of human beings. This type of person's chest - the neck, upper arm and other parts are prone to obvious scars. Even the same is often found in members of the family. In fact, there are keloids in the earlobe, and other parts of the body often find the same lesion. Second: related to surgical operations. If the operation is not strict, the bacteria or foreign body is brought into the wound, and the wound is not infected repeatedly, it is easy to produce keloids. Third: Medical research shows that the nickel needle or some metal earrings used in the ear hole will produce local contact dermatitis in the case of ear skin damage, which will promote keloid production.

Diagnosis
Differential diagnosis
Differential diagnosis of a mass that grows at the ear hole:
1. Tympanic scarring: Tympanic membrane scarring produces tympanosclerosis, tympanosclerosis is also called tympanic glass degeneration, plaque-like collagen tissue is deposited under the mucosa of the tympanic membrane, which occurs on the tympanic membrane mucosa and the ossicle, which occurs on the tympanic membrane. Still known as calcified plaque, the tympanic mucosa becomes a milky skin-like substance, covering the ossicles, the oval window and the round window, and sticking to the bone, as if coated with a layer of coating, involving the upper tympanic cavity, Those who are involved in the lower tympanic cavity are lighter, and the hammer bone, the anvil bone, the tibia and the tendon are most susceptible, so many people are deaf. This disease was discovered by Cassebohm in the 18th century, but it did not attract attention. It was not until the modern (1955) a large number of microsurgical operations.
2, the submental area of the tough mass: parotid mixed tumor or pleomorphic adenoma is a kind of parotid gland tumor containing parotid tissue, mucus and cartilage-like tissue, it is called "mixed tumor". Mucus and cartilage-like tissue are metamorphosed by glandular tissue. The outer layer of the tumor is a very thin envelope that is formed by deformation of the parotid gland after compression and is not a true envelope.
Clinical symptoms: a mass grows in the ear hole.
