Cytopathology of nipple discharge due to Pityrosporum orbiculare and cocci in an elderly woman.

A case has been described where cytologic examination first showed a fungus infection as the possible cause of a nipple discharge of long duration. The discharge was found to be associated with Pityrosporum orbiculare, Micrococcus tetragenes and Staphylococci (coagulase negative). Administration of an antibiotic that inhibited the bacteria cured the condition.
