<s>[INST] Today, my nurse practioner noticed a soft lump in the middle of my chest--no skin discoloration nor have I noticed it before. I cant remember the medical term she gave it; however she mentioned that it could be a fatty deposit and a Dermatologist could drain it and referred me to one. Im looking for the medical term so that I can give that information to the my dermatologist? [/INST] Hi.it is best if you consult with a doctor, preferably a general surgeon, for medical and physical examination. Based from your description, it could be a cyst (a sebaceous or a gelatinous type), a fibrous, or a lipoma (fatty deposit). These lesions can occur anywhere in the body and have the tendency to recur.  Management (medical and surgical) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.  </s>
