[|Human|] Right underarm presents with one lump (under the skin), very soft to touch with no pain, less than 1 cm in longest axis. Have experienced itching & irritation on both armpits. I am a Liver allograft transplant patient, stable for 9 years with 1mg. Prograf (every 12 hours), 180 mg. Myfortic (every 24 hours) & 5mg. Prednisone every 24 hours. Cause of Transplant, PSC. Had a cold about 4 weeks ago with ever decreasing cough -almost resolved. No significant night sweats -only some sweat in areas in contact with bed occasionally. I have been diagnosed with C. Difficile Colitis -recurrent (chronic).
[|AI|]  Hi and welcome to Chat Doctor. Thank you for your query. I am Chat Doctor and I will try to help you as much as I can. I don't think this lump is related to your previous diseases. This sounds to me like a lipoma and this is soft subcutaneous lesion which can be easily surgically removed under local anesthesia so consult your doctor about it. I hope I have answered you query. If you have any further questions you can contact us. Kindly regards. Wish you a good health.
