<s>[INST] My husband had stiches on the side of his middle finger about a year ago.  When it healed there was a small bump....we thought scar tissue.  Over the last couple of months it got bigger.  It was very hard, like a callous.  Today he pressed on it and puss came out.  A large rubbery thing came out of it, it was solid white.  No pain, some blood....what the heck was it? He is 38, 59,  155lbs....no medical issues. [/INST] Hi. Welcome to Chat Doctor . I have gone through your query and can understand your concerns. As per your complaint it seems that there is formation of Keloid at the site of stitches that is an Overgrowth of scar tissue. At times the scar tissue grows more than normal and leads to formation of a hard growth. It seems that there is infection at the Keloid site leading to pus discharge. I would suggest you to consult a General Physician and get evaluated, and a clinical examination can help in diagnosis and treatment can be done. In case of infection first you will be advised to clean the area with antiseptic solution. Application of Triple Antibiotic Ointment can be advised. Once the infection resolve the Physician can advise you Silicone patches, pressure Chat Doctor. . Steroid injection can be given in the Keloid in an attempt to shrink it. You can also be advised Cryotherapy, later and radiation to shrink the Keloid. Hope this information helps. Thanks and regards. </s>
