title: Intracytoplasmic eosinophilic inclusion bodies in benign breast cyst fluids.
abstract: Intracytoplasmic eosinophilic inclusion bodies (EIBs) observed in cytologic preparations of benign breast cyst fluid aspirates were morphologically similar to the well-known EIBs in urine specimens. EIBs have not been previously described in breast cyst fluids. A chi-square test proved a statistically significant correlation between the presence of intracellular EIBs and cellular degeneration. The possible significance of this finding with regard to the origin of EIBs is discussed.
