[|Human|] 28-year old man: a lump/bump on the upper arm and on top of the shoulder appeared suddenly one after another within 2 days. One of them (on the sholder) is almost round and the other one (on the upper arm) is ellipsoid-like and is about 1.5 long and about 2/3 wide. What could that be?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Multiple lump can be lipoma or neurofibroma. You should go for biopsy of one lump and ho for histopathological examination.  Excision is the treatment of choice for both.  Consult your doctor and 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.
