Resumo: Abstract: Recurrent melanocytic nevus is a proliferation of melanocytes arising from a melanocytic nevus removed partially. Asymmetry and irregular pigmentation may lead to misdiagnosis of melanoma. We report a patient presented with a lesion on the lower abdomen, which was removed by shave excision. Anatomopathological examination revealed an intradermal melanocytic nevus. Two months later, a new irregular hyperpigmented lesion appeared in the surgical scar. Histopathology of the excisional biopsy revealed a recurrent melanocytic nevus. Recurrent melanocytic nevus manifests as a scar with hyper or hypopigmented areas, linear streaking, stippled pigmented halos, and/or diffuse pigmentation patterns. Histologically, the dermoepidermal junction and the superficial dermis show melanocytic proliferation overlying the scarred area. When a pathological report of the previous lesion is not available, complete excision is the gold standard. Otherwise, regular dermoscopic monitoring is a therapeutic option. The present report emphasizes the importance of histopathological examination of the excised material - even in cases of suspected benign lesions - and warns patients about the possibility of recurrence in case of incompletely removed lesions.
