Uncommon presentation of necrotizing fasciitis affecting the breast in a young breastfeeding patient: Case report

Abstract

Introduction and importance: Necrotizing fasciitis is a highly dangerous infection that poses a life-threatening risk as it rapidly spreads and causes tissue necrosis in the subcutaneous tissues and fascia. Although rare, the breasts can be affected by this infection, which adds to the complexity of the condition.

Case presentation: A 26-year-old woman who had been breastfeeding for two months presented with pain, swelling, and fever in her left breast. The left breast showed skin darkening and foul-smelling discharge. The diagnosis was septic shock due to necrotizing fasciitis. Prompt treatment included surgical debridement, broad-spectrum antibiotics, and supportive care. The patient's condition remained challenging, and the infection was caused by multi-resistant bacteria.

Clinical discussion: Necrotizing fasciitis is a highly severe and aggressive type of soft tissue infection. It can range from minor or mild infections of the soft tissues to severe cases involving septic shock. While it is uncommon, necrotizing fasciitis can also affect the breasts. The diagnosis of breast NF relies on a combination of clinical evaluation, culture results, laboratory findings, and imaging studies. Swift surgical interventions, along with appropriate antibiotic therapy and supportive management, are vital for the patient's survival and improved prognosis.

Conclusions: Breast necrotizing fasciitis is frequently misdiagnosed due to the presence of thick breast tissue, which creates challenges in identifying the infection between the skin and deep fascia. Swift and extensive surgical debridement, combined with the administration of broad-spectrum antibiotics, are crucial components for effectively managing and preventing the significant morbidity and mortality associated with this condition.
