A Case Report of Severe Mastitis Leading to Breast Necrosis and Toxic Shock Syndrome during the Puerperium.

Postpartum mastitis is common, but immunological changes specific to the postpartum period can exacerbate the inflammation. We report a case of methicillin-resistant Staphylococcus aureus-associated mastitis that rapidly progressed, leading to breast necrosis and symptoms resembling toxic shock syndrome. Postpartum mastitis can result in severe symptoms, so early detection and intervention are important.
