Abstract:
SUMMARY: Demodex folliculorum (D. folliculorum) is a human ectoparasite that resides in the pilosebasceous skin unit. Common sites
of predilection are the skin of cheeks, forehead, nose, nasolabial fold and eyelids. Genital D. folliculorum inoculation case reports are
extremely rare and depend on investigation of skin lesions. There is no study of genital skin without lesions, and, as far as we know,
there is no literature on D. folliculorum prevalence in male genital skin. We examined D. folliculorum prevalence on the healthy scrotum
and male perineum. One hundred males were examined for D. folliculorum on facial and genital skin. Samples were taken from cheek,
forehead, scrotum and perineum by standard skin surface biopsy (SSSB) or hair epilation. The mean age was 53.5±13.0 (24-70) years.
Eight percent of males had D. folliculorum on their facial skin. Mean Demodex density (Dd) of men with D. folliculorum positivity was
5.1± 2.9/ cm2
(2-9/cm2
). Diagnostic results of both sampling methods were similar. No D. folliculorum was demonstrated on genital skin.
