Abstract
- Poikiloderma of Civatte (PC) is a common, acquired condition that affects the face, neck, and upper chest of elderly persons due to life-long sun exposure. Poikiloderma describes skin manifestations of atrophic and telangiectatic lesions with pigmentary changes. We experienced three cases of patients who visited our department due to whitish patches on the anterior neck, which had been treated as vitiligo at private dermatological clinics. The patches mimicked vitiligo to the naked eye due to their color and relatively well-demarcated margin, but they were not accentuated under Wood's light. On MART-1 staining, there was no loss of melanocytes in the basal cell layer of the epidermis. Leukoderma on the anterior neck might be produced due to contrast with the neighboring skin showing PC. Based on our experiences, we propose a new dermatological term, 'leukoderma nuchae (LN)', to describe the spared zone of PC, to aid in differentiating this condition from vitiligo.
