PYOGENIC MEMBRANE MORPHOLOGY AS THE KEY CRITERION FOR SELECTING OPERATIVE VOLUME IN NON-LACTATIONAL PURULENT MASTITIS

Abstract

The pyogenic membrane is the key morphological structure of a non-lactational abscess, consisting of an inner neutrophilic layer and an outer granulation tissue of varying degrees of maturity. In mature pyogenic membranes (>4 mm), Corynebacterium kroppenstedtii forms biofilm within the fibrous capsule, ensuring pathogen persistence even after adequate drainage, which constitutes the principal mechanism of recurrence [1, 3]. The role of pyogenic membrane morphological maturity in predicting recurrence and selecting the operative volume in non-lactational purulent mastitis (NPM) has not been sufficiently studied in available literature [4, 5]. Recurrence rates with standard incision and drainage (I&D) without morphological stratification reach 15–50% [2].
