[|Human|] My boyfriend has a large fluid like lump, about 1 and 1/2 inches in diameter.  It was noticed for the first time about a day ago and is now bigger.  If you push the lump with your finger, it stays indented for a short period then returns to the swollen position.  Hes had no head trauma, and no other sypmtoms.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He may have some Desmond cyst, sebaceous cyst, other benign cyst or soft tissue tumor. You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
