Necrotising fasciitis in a patient treated with FOLFIRI-aflibercept for colorectal cancer: a case report.

Anti-angiogenics have become an important part of the treatment of several types of tumours such as ovarian, breast, lung and colorectal cancer. Necrotising fasciitis has been reported with bevacizumab but no cases have been reported with aflibercept, ramucirumab or regorafenib in patients with colorectal cancer. Necrotising fasciitis is a rare complication affecting one in 5000 bevacizumab users. We report the case of a 64-year-old man with stage IV rectosigmoid cancer under treatment with folinic acid, fluorouracil and irinotecan (FOLFIRI) and aflibercept, who developed a Fournier's gangrene.
