Facklamia hominis isolated from infected sebaceous cyst on the breast

Facklamia hominis is a gram-positive, catalase-negative, facultatively anaerobic coccus that is a rare human pathogen, with fewer than 15 cases isolated in the literature. We present the case of a 62-year-old female with an infected left breast sebaceous cyst treated successfully with surgical excision and flucloxacillin. Subsequent culture and microscopy isolated the organism Facklamia hominis. To the best of our knowledge, this is the first reported case of Facklamia hominis isolated from the breast, and the first reported isolate of the organism from a clinical specimen in Australia.
