The Clinical and Dermatoscopic Features of Penile Pigmentation in Men with Genital Lichen Sclerosus

We propose that genital lentiginosis and melanosis are clinically indistinguishable macroscopically and are on a clinical and histopathological spectrum. Although there is a compelling narrative that genital melanosis is most often truly benign, there is also emerging evidence to suggest an increased risk of penile melanoma in patients with MGLSc. Furthermore, pigmented lesions in MGLSc can portray concerning morphological features even when benign. A low threshold for biopsy and follow-up is thus warranted.
