Fulminant gas-forming breast abscess associated with synergistic Veillonella infection.

We present a rare case of a rapidly fulminant and destructive breast abscess with gas production by the synergistic infection of Veillonella and Streptococcus species. To our knowledge, this is the first reported case of Veillonella infection in the breast. Early recognition, empiric antibiotic cover, aggressive surgical debridement, and drainage are necessary to avoid systemic septicemia. Staged reconstructive breast surgery allows for correction any resultant breast deformity.
