Abstract: | BACKGROUNDThe dermoscopic features of vulvar melanosis lesions are well known. To our
knowledge, there are only a few case reports about dermoscopic features of
pigmented genital lesions in male patients.OBJECTIVETo evaluate dermoscopic and clinical characteristics of benign lesions of the
genital area in both males and females, and to assess the distinguishing
dermoscopic criteria of vulvar melanosis and atypical melanocytic nevi of
the genital type.METHODS68 patients with pigmented genital lesions were included in this
observational study (28 male and 40 female). A punch biopsy was taken from
all pigmented lesions and histopathological examination was performed on all
specimens.RESULTSWe histopathologically diagnosed: genital melanosis in 40 lesions, atypical
melanocytic nevi of the genital type in 15 lesions, melanocytic nevi in 9
lesions, seborrheic keratosis in 4 lesions. The most frequent locations were
the glans penis (19 patients, 67.9%) in males and the labia minora (19
patients, 47.5%) in females. The mean age of patients with atypical nevi
(28,6 ± 11,36) was significantly lower than the mean age of patients with
genital melanosis (47,07 ± 15,33).CONCLUSIONSParallel pattern is prominent in genital melanosis, ring-like pattern is only
observed in genital melanosis. Most pigmented lesions on the genital area
are solitary. Blue-white veil and irregular dots are only observed in AMNGT.
According to these results, we propose that histopathological examination is
performed, especially if blue-white veil and irregular dots are found by
dermoscopy. |
