Necrotizing Fasciitis of the Breast Following a Core-Needle Biopsy.

Necrotizing fasciitis (NF) is an aggressive rapidly spreading infection of the skin and the subcutaneous tissue. Its occurrence in the breast is extremely rare especially after routine procedures like core-needle biopsy. We present the case of a 35-year-old non-lactating female who presented with swelling and a necrotic patch with pus discharge over her right breast following a core needle biopsy. She was immediately treated with aggressive debridement and culture-specific intravenous antibiotics following which she had an uneventful recovery. It is quintessential to diagnose the condition and initiate the treatment as early as possible to prevent the progression of the disease to sepsis and multi-organ dysfunction.
