In vivo reflectance confocal microscopy findings in a case of atypical fibroxanthoma.

Clinical and dermoscopic features of atypical fibroxanthoma (AFX) are mostly non-diagnostic, so other in vivo diagnostic tools may give additional clues for accurate clinical diagnosis, such as in vivo reflectance confocal microscopy (RCM). However, there has been scarce data on RCM features of AFX in the literature, in only clear cell type. Herein we present a case of epithelioid cell predominant type AFX with RCM findings.
