R. Hausmann et B. Schellmann, FORENSIC VALUE OF THE LUGOL STAINING METHOD - FURTHER-STUDIES ON GLYCOGENATED EPITHELIUM IN THE MALE URINARY-TRACT, International journal of legal medicine, 107(3), 1994, pp. 147-151
This study presents findings from a series of investigations on the pr
esence of glycogenated epithelium in the male urinary tract and on the
penile surface in order to assess the forensic value of the Lugol's m
ethod for the identification of vaginal cells. Direct smears obtained
from the urethral opening, glans penis, and penile shaft, along with p
ost-mortem samples of the fossa navicularis, and histological sections
of the penis were examined. The presence of polygonal, glycogenated,
Lugol-positive epithelium cells in the male urinary tract was found to
be common. Our results suggest that these cells originate from the fo
ssa navicularis. Because of the possibility of exfoliation of glycogen
ated male cells and transfer to the penile surface a Lugol-positive re
action in epithelial cells on penile swabs can no longer be assumed to
prove the presence of vaginal cells.
