[|Human|] Hi Dr,I have a lump on the top off my arm when squeezed a white discharge comes out ( there is a smell)  has been there for yrs, each time its squeezed ... It seems no more comes out till it builds up and it becomes a prominent lump once again.  Now its bigger then before hasnt been touched in a while, it isnt painful until squeezed until it goes from white discharge to clear then a bit of blood. What is it? And how do I get rid of it? Regards Nikki
[|AI|]  Hi, this is a Sebaceous cyst or a Desmond cyst. It is a common swelling in all parts of the body. They are cysts collected with Sebum or secretions of the Sebaceous glands in the skin. The only definitive treatment is removal by Surgery. Pinching it and squeezing it are not advisable as this can lead to infections. It can cause redness and pain. I suggest you get it removed by a small Surgery and can be done by any Surgeon under local anesthesia without getting admitted to the hospital. So, I suggest you get it removed and get rid of it. Take care, Chat Doctor.
