-
Wound infection due to disturbed coagulopathy. This patient has a pacemaker (visible below right clavicular space) and had previous cardiac surgery (median sternotomy wound visible) for a rheumatic mitral valve disorder, which was replaced. The patient was taking anticoagulants preoperatively. Despite converting to low-molecular weight subcutaneous heparin treatment and establishing normal coagulation studies, she developed a postoperative hematoma with subsequent wound infection. She had the hematoma evacuated and was administered antibiotic treatment as guided by microbiological results, and the wound was left to heal by secondary intention.

Large ulceration in a tattoo. A 33-year-old man presented with a superficial ulceration about 4 weeks after a red tattoo on his forearm. Microbial swabs remained negative. His medical history was uneventful and he was in good general health. No reason for this uncommon reaction could be identified. Image courtesy of the National Institutes of Health.
