title: Breast abscess: coagulase-negative staphylococcus as a sole pathogen.
abstract: Breast abscesses in nonlactating women are very uncommon. Rarely have cases been reported in which coagulase-negative staphylococci have been isolated in pure culture. We describe a 67-year-old patient who had such an abscess. Specimens obtained by fine needle aspiration, incision and drainage, and biopsy of the breast mass all showed acute inflammation and many gram-positive cocci on gram stain and histologic examination; cultures of all specimens yielded many coagulase-negative staphylococci. The patient responded well to incision and drainage and therapy with antibiotics.
