Abstract
Necrotizing fasciitis of the breast is a rare but potentially fatal soft tissue infection. It may occur primarily in patients without any direct cause, and less commonly after undergoing elective surgical procedures such as cosmetic mammoplasties and oncologic resections. This is a case of a 46-year-old female with stage IIIA invasive ductal carcinoma of the left breast treated with modified radical mastectomy presenting with a necrotizing infection involving the bilateral breast regions and left lateral abdomen six days after operation. She was managed with broad-spectrum antibiotics and radical debridement with right mastectomy, followed by wound coverage with split-thickness skin grafting. This is the eight case of breast necrotizing fasciitis occurring after mastectomy for breast cancer reported in the literature.
