Helcococcus kunzii as sole isolate from an infected sebaceous cyst.

Helcococcus kunzii was isolated in pure culture from pus drained from an infected sebaceous cyst associated with marked cellulitis. The cyst was excised one month later after the inflammation had subsided with flucloxacillin treatment. This is the first report of the isolation of H. kunzii as the sole pathogen from an infected site.
