Medical Intelligence & Overview
A puerperal breast abscess, classified under ICD-10 code O91.12, is a localized infection that occurs in the breast tissue after childbirth. It often results from an infection of the milk-producing glands and surrounding tissues, typically developing during the puerperium period—the time following childbirth when the body is recovering and breastfeeding is initiated. This condition is also known as puerperal mastitis and can involve an abscess formation, which is a pocket of pus encased within inflamed tissue. Recognizing the signs and understanding the causes of this condition are crucial for early management and treatment.
