Eccrine chromhidrosis: visualization through 405-nm sub-ultraviolet reflectance dermoscopy and polarized dermoscopy

Dermoscopic examination of eccrine chromhidrosis reveals pigmentation around the eccrine pores on the ridge, which may reflect the presence of coloured compounds secreted by the eccrine glands. The absence of pigmentation in the furrows, where eccrine pores are not present, supports this observation. We believe that defining the dermoscopic findings of eccrine chromhidrosis will be helpful in the diagnosis and differential diagnosis of the disease.
