| Abstrakt: | Spontaneous appearance of hyperpigmented macules on chronic vitiligo lesions is a very rare phenomenon, which is described as eruptive lentiginosis. We describe the case of a patient with chronic non-segmental generalized vitiligo who presented with a sudden onset of hyperpigmented macules on depigmented areas of the face. A biopsy showed pigmented basal keratinocytes in the interfollicular epidermis, and immunohisochemistry with anti-SOX10 antibodies showed nuclei of single melanocytes. This case shows that even long-standing depigmented vitiligo lesions may contain functional melanocytes or their precursors. |
