title: [Monstrous epithelium in the seminal vesicles and epididymis].
abstract: Monstrous epithelial cells in seminal vesicles, causing diagnostical embarrassment , occur sometimes in fine needle-aspirates of prostate gland. Their frequency was studied in a group of autopsies (6 boys of the age from 6 hours to 10 years, mean age 3,1 years and 34 adult men of the age from 42 to 91 years, mean age 68,4 years). Monstrous cells did not occur in boys but were found in 73,5% of adults. There were similar epithelial monstrosities in epididymis simultaneously. Most of them were found in efferent ductuli (in 76,4%). Big monstrous epithelial cells with conspicuous irregular hyperchromatic nuclei are to be distinguished cautiously from the neoplastic ones. They may be caused by ageing and hormonal influence above all (in analogy to Arias-Stella phenomenon in women).
