<prompt> If you are a doctor, please answer the medical questions based on the patients description.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?  <response>: 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.
