Little is known about the use of dermoscopy in skin grafting. We describe the case of a patient with skin grafting and surrounding pigmentation on acral region. The dermoscopic findings were similar to those of benign acral lesions (lattice-like pattern) and reactive pigmentations (fine striae). Histopathology revealed pigment leakage and increased number of melanocytes. It is believed that this phenomenon occured as the result of an inflammatory stimulus.

Os autores relatam caso clínico de paciente do sexo masculino, diabético do tipo II insulinodependente, que apresentava lesões eritêmato-acastanhadas no abdômen e nas coxas, com ligeira atrofia assintomática. O exame histopatológico das lesões revelou a combinação de angiopatia e alterações leves do colágeno, compatíveis com o diagnóstico de dermopatia diabética.
