It commonly mimics more invasive neoplasms and is a diagnostic challenge to clinicians. The aim of this study was to develop a better understanding of AFX, focusing on recent developments in diagnosis and management.</span></p><h4 style="font-size: 13px; margin: 0px 0.25em 0px 0px; text-transform: uppercase; float: left; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">METHODS:</span></h4><p style="margin: 0px 0px 0.5em; line-height: 1.538em; font-size: 1.04em; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">A retrospective case series and review of recent literature were carried out.</span></p><h4 style="font-size: 13px; margin: 0px 0.25em 0px 0px; text-transform: uppercase; float: left; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">RESULTS:</span></h4><p style="margin: 0px 0px 0.5em; line-height: 1.538em; font-size: 1.04em; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">Over a 17-year period, seven cases were identified (six male, mean age at presentation was 75.9 years). Two patients underwent complete excision and five patients had curettage and cauterisation. Two patients developed local recurrence but none demonstrated signs suggestive of metastatic spread. Histologically all seven lesions displayed a spindle cell pattern. Where performed, immunohistochemical staining was positive for Vimentin, CD10, CD68 and actin, and negative for CAM 5.2, CD34, Melan-A, S100 protein, HMB45, Cytokeratin A1/A3.</span></p><h4 style="font-size: 13px; margin: 0px 0.25em 0px 0px; text-transform: uppercase; float: left; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">CONCLUSION:</span></h4><p style="margin: 0px 0px 0.5em; line-height: 1.538em; font-size: 1.04em; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">Our patient demographics, histopathology and immunohistochemistry are comparable to previous studies. Although advances have been made in immunohistochemical analysis, we are yet to discover a specific diagnostic immunostain for AFX. Clinical findings should therefore be correlated with histology and a panel of immunohistochemical stains should be used. Given the potential for recurrence or metastases, Moh's Micrographic Surgery with regular follow-up may be the preferred management.</span></p>
