Baker's Cyst
Baker’s cyst is a swelling on the back of the knee caused by the build-up of fluid inside sacs called bursae. The symptoms are mild unless the cyst bursts or extends down into the calf muscles. Common causes of Baker’s cyst include arthritis, infection, torn knee cartilage and other knee injuries. Baker’s cyst is also known as a popliteal cyst.
Ganglion Cyst
A tendon is a tough band of connective tissue that joins muscle to bone. Tendons and joints have a covering of membrane that produces a lubricating fluid to assist their function. A ganglion cyst is a benign (non-cancerous) ball of fluid that grows on the membrane or sheath that covers these tendons and joints. The backs of the hands and wrists are most commonly affected, but ganglion cysts can sometimes grow on the feet, knees and ankles. A ganglion cyst is the most common lump on the hand, and tends to target women between the ages of 20 and 40 years of age, for reasons unknown.

Watching For Sebaceous Cysts
A sebaceous cyst is a sac under the skin that is enclosed in a lining. This lining is similar to the topmost portion of a hair follicle and contains a fatty white, partially solid matter referred to as sebum. Sebum is generated by sebaceous glands of the epidermis. The surface of the skin, or epidermis, comprises of a very thin, safeguarding layer of cells that your body constantly sloughs off. The majority of epidermoid cysts develop when these cells, rather than shedding as usual, travel deeper into the skin and proliferate. Usually, this happens in parts where there are tiny hair follicles and bigger sebaceous glands, like on the face, neck, groin and upper back. The epidermal cells make up the walls of sebaceous cysts, and then emit the protein keratin into the inner areas. The keratin is the thick yellow matter that occasionally draws off the cyst.
