Necrotizing Soft Tissue Infection of the Breast: A Unique Presentation of Underlying Invasive Breast Cancer

Year: 2025

Type: article

Abstract: Necrotizing soft tissue infections (NSTIs) are life-threatening infections that most commonly affect the extremities, perineum, and abdominal wall. These infections begin with the presence of toxin-producing bacteria that invade through a defect in the skin barrier, such as a wound, laceration, trauma, or recent surgical incision. These bacteria cause subsequent tissue destruction and necrosis that can involve the superficial skin, subcutaneous tissue, fascia, and/or muscle. NSTIs can progress quickly, leading to severe sepsis, shock, and even death. NSTIs associated with the breast are an exceedingly rare occurrence, requiring early diagnosis and prompt surgical intervention. In this article, we report the case of a 46-year-old woman with an NSTI of the left breast, which required serial debridement initially, and subsequently a modified radical mastectomy given a pathological diagnosis of invasive ductal carcinoma.
