We describe a patient with an incidental finding of prostatic tissue i
n the uterine cervix. There was immunohistochemic;ll evidence of its p
rostatic nature, as shown by its positivity to prostate-specific antig
en (PSA) and prostate acid phosphatase (PAP), and female genetic profi
le was confirmed by the fluorescence in situ hybridization (FISH) tech
nique. To our knowledge this is the first report of prostatic tissue i
n the uterine cervix, and of the use of the FISH technique to exclude
mil;matching of the biopsy material with a male prostate.
