A halo nevus is characterized histologically by the progressive degeneration of melanocytes, which are destroyed by an inflammatory infiltrate that is very prominent initially and that gradually diminishes.

Although the cytokine microenvironment does not seem to fully explain the development of fibrosis in melanoma regression (which is also related to interactions between the tumor, the stroma, and the inflammatory infiltrate), the elevated expression of TNF-α in halo nevi suggests that it plays an important role in inhibiting fibrosis in these lesions.<a class="elsevierStyleCrossRefs" href="#bib0080"><span class="elsevierStyleSup">16,36–38</span></a></p><p id="par0235" class="elsevierStylePara elsevierViewall">In addition, the inflammatory infiltrate that leads to regression in melanoma is usually asymmetrical and patchy, affecting only parts of the tumor.

Clinically, these nevi involuted very rapidly. On histology, extremely thin collagen bundles were seen to have created a particular pattern of fibrosis referred to as delicate (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>). In all our cases, dermoscopy confirmed complete involution of the nevus within a much shorter period (mean of 6.4 months) than is observed in halo nevi. Loss of structure and the presence of multiple pepper-like granules (which is correlated with a histologic finding of melanophages) were the main dermoscopic findings (<a class="elsevierStyleCrossRef" href="#fig0040">Fig. 8</a>). In most cases, the morphologic features of the residual lesion were very similar to those seen in lichenoid keratosis. Although follow-up was not long in our series (ranging between 1 and 3 years), there were no cases of metastasis.</p><elsevierMultimedia ident="fig0040"></elsevierMultimedia><p id="par0170" class="elsevierStylePara elsevierViewall">Certain characteristics suggest that the lesions we studied were not conventional halo nevi. The signs of regression also differed from those seen in melanoma regression. One difference was that none of the nevi in our series developed a clinically evident white halo. In addition, although it is common for patients to have several similar halo nevi, none of our patients had other regressing nevi and involution occurred in much less time than halo nevi take to form.</p><p id="par0175" class="elsevierStylePara elsevierViewall">Immunohistochemistry confirmed the complete absence of nevus cells in these cases. Our observations included melanophages (<a class="elsevierStyleCrossRef" href="#fig0020">Fig. 4</a>), present in varying degrees and extensive in only 2 cases; inflammatory infiltrates (<a class="elsevierStyleCrossRef" href="#fig0025">Fig. 5</a>), mild or moderate in most cases; vascular proliferation (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>); and a particular type of fibrosis consisting of fine collagen bundles that were often located subepidermally (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>) and that have not been described in halo nevi or melanomas to date. In melanoma, fibrosis is usually dense but in halo-nevus formation it does not develop in the final stages. Fibrosis is generally a less significant finding in conventional nevi undergoing spontaneous regression than it is in regressing melanomas; an exception is the sclerosing nevus with pseudomelanomatous features that has recently been described.<a class="elsevierStyleCrossRefs" href="#bib0210"><span class="elsevierStyleSup">42–45</span></a> Such nevi are trizonal, consisting of an area of proliferating atypical melanocytes with pagetoid spread, an area of significant dermal sclerosis containing irregular nests of melanocytes, and an area of residual nevus tissue around and below the scar. Structural changes in these melanocytic neoplasms are usually so pronounced that they sometimes lead to a diagnosis of melanoma with regression or nevus-associated melanoma with regression. Nonetheless, the cytologic criteria essential for a diagnosis of melanoma are not met in most of these cases and to date complete regression has not been reported.</p><p id="par0180" class="elsevierStylePara elsevierViewall">Delicate fibrosis, such as we observed in the nevi in this series, can be distinguished from the laminar fibrosis typical of a dysplastic nevus because parallel and/or concentric fibrotic bundles will not be present. Instead, thin collagen fibers will be scattered in the lesions and cellularity will be reduced and without signs of significant activation. In the absence of activation, the lesion can be considered stable and at the end of the fibrotic process, which will not continue on toward more organized patterns (as in a dysplastic nevus) or thickened bundles (as in melanoma regression). Therefore, we conclude that even though we removed the nevi within a very short period (in less than 2 weeks of noticing the changes), a biopsy performed at a later date would not have shown laminar fibrosis or thick bundles. The process would more likely have abated and the tissue would probably have been more similar to normal skin.</p><p id="par0185" class="elsevierStylePara elsevierViewall">A melanoma in regression is usually accompanied by intense melanophage formation, and many authors consider nodular melanosis (extensive melanophage deposition) to be a key criterion for a diagnosis of complete melanoma regression.<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">14</span></a> In our case series, however, the inflammatory infiltrates were less intense than is typical for halo nevi and the most common phenotype we observed was that of CD8<span class="elsevierStyleSup">+</span> T-cell predominance (<a class="elsevierStyleCrossRef" href="#fig0045">Fig. 9</a>), resembling halo nevi and different from a regressing melanoma (where CD4<span class="elsevierStyleSup">+</span> T cells predominate) (<a class="elsevierStyleCrossRef" href="#tbl0020">Table 4</a>).</p><elsevierMultimedia ident="fig0045"></elsevierMultimedia><elsevierMultimedia ident="tbl0020"></elsevierMultimedia><p id="par0190" class="elsevierStylePara elsevierViewall">The type of regression in this series most probably originated in an immune response to antigens expressed only by melanocytes in the affected nevus and not by those in the adjacent skin. These antigens would not have been widely expressed in other nevi on the patient's body, as happens in halo nevus formation and leads to events analogous to an explosion involving massive and extremely rapid destruction of tumor cells. The process we observed suggests a cytotoxic mechanism (confirmed in these cases by the marked predominance of CD8<span class="elsevierStyleSup">+</span> T cells) that was initiated by an inflammatory infiltrate acting very rapidly and disappearing early. The marked expression of major histocompatibility complex class I molecules by melanocytes makes them vulnerable to attack and destruction by cytotoxic T cells. Antigens that are expressed on the membrane of melanocytes and that are normally tolerated by the immune system probably undergo some type of change that makes them targets of these T cells. Once the cytotoxic T cells recognize the foreign antigens, they would induce cell death by mechanisms involving both FAS-ligand expression and direct damage to the cell membrane on release of perforin. Damage to the target cell may then amplify the immune response by releasing cytoplasmic antigens that would normally be inaccessible to the immune system.<a class="elsevierStyleCrossRefs" href="#bib0130"><span class="elsevierStyleSup">26,32</span></a></p><p id="par0195" class="elsevierStylePara elsevierViewall">The delicate fibrosis observed would be explained by the rapidity of the regression process and by superficial repair.</p><p id="par0200" class="elsevierStylePara elsevierViewall">The loss of dermoscopic structure in most lesions correlated with a finding of delicate or laminar fibrosis on histology. All lesions with multiple pepper-like granules on dermoscopy also showed moderate or intense presence of melanophages on histology. Vascular proliferation was the variable with the least correlation between dermoscopy and histology, as blood vessels were evident dermoscopically in only 7.6% of cases.
