Background:
@EN There are 2 views with regard to the treatment of pigmented nevi present on the palms, soles, and genitalia. One advocated that pigmented nevi on these locations should be prophylactically removed to avoid their future development into
malignant
melanoma, while the other believes that this is not practicable.
@ES Objective:
@EN Our purpose was to determine the incidence rates and clinical characteristics and to discuss the management of pigmented nevi, developed on these areas of the Korean men.
@ES Methods:
@EN We examined 1,537 Korean men, between 19 and 21 years old, to evaluate the pigmented nevi on their palms, soles, and genitalia.
@ES Results:
@EN At least 1 pigmented nevus appeared in 314(20.4%) men on the palms, 189(12.3%) on the soles, and 117(7.6%) on the genitalia. The sizes(mean diameter) of vevi on genitalia, soles, and palms were 4.5mm, 3.1mm, and 2.3mm respectively. The color
of
the
nevi was darkest on the penile shaft(4.3 point) and then glans penis(3.9 points), soles(3.2 points), palms(2.5 points) in decreasing orders of the points. Most of the nevi were consistent with type 1 by Lever's clinical classification and their
incidence were 357 on palms, 211 on soles, and 128 on genitalia. Among the 21 nevi of type 2, 13 nevi appeared on the soles, and none of type 3 and type 5 were found. The distribution of the nevi on the palms was of a rather uniform and scattered
pattern, whereas, on the soles, they were distinctly concentrated in the midfoot. The nevi on the glans penis appeared larger and more irregular in outline than those on the penile shaft.
@ES Conclusion:
@EN The plantar nevi were larger, darker, and had grater incidence of elevated type compared with the palmar nevi. From this observation, particular attention should be paid to the presence of pigmented nevi on the soles.
