There is a hard lump on my knee

The knee is a bone that protrudes from the human leg, so when there is a problem with the knee, people can observe it immediately. And knee problems are also a problem that we cannot ignore. If we ignore the problems with the knees, the knee condition will become more serious. Some patients have hard lumps on their knees. Could these hard lumps on the knees be caused by skin cysts?

1. Furuncle: Furuncle is a purulent infection of hair follicles and the surrounding tissues deep inside the hair follicles. Furuncles may be caused by bacterial infection, air or food allergies, life stress, poor hygiene, illness, poor resistance, certain medications, eating too much junk food, wound infection, blood poisoning, or thyroid problems. It is painful, unsightly, sometimes leaves scars, and occasionally even dangerous.

2. Lipoma: Lipoma is a common benign tumor. It is caused by poor eating habits and excessive intake of fatty and high-cholesterol foods, which lead to excessive production of new adipose tissue, causing excessive fat cells in the body to aggregate and harden. Excessive work pressure and irritability can cause normal fat tissue and blood stasis to be intertwined. Over a long period of time, connective tissue can form to wrap around fat cells and form lipomas.

3. Sebaceous cyst: Sebaceous cyst is commonly known as "sebaceous cyst". It is a retention cyst formed mainly due to obstruction of the sebaceous gland excretion duct, which causes the sebaceous gland cystic epithelium to swell with the gradually increasing contents. It is characterized by a slowly growing benign lesion. There is white bean curd-like secretion in the cyst.
