Halo phenomenon with regression of acquired melanocytic nevi: a case report

We report a 19-year old girl with halo- phenomenon in excisional biopsy of junctional nevi. The diagnosis was established histopathologically because of lack of clinical halo and unspecific dermoscopic features. Clinico- pathologic difficulties in establishing the diagnosis of these pigmented lesions, aetiopathogenesis and differential diagnosis of halo nevi is emphasised. Dermatologists should be familiar with possible changes in benign melanocytic nevi, halo reactions and possible complete regression of melanocytic nevi. Diagnostic difficulties are seen at the ultimate phase of regression when the melanocytes are diminished or destroyed with immunologic reaction.
