Figure 2. RCM and Histopathologic Images of the Lesion.

Figure 2.

A, Reflectance confocal microscopy (RCM) image shows large nucleated, dendritic cells (yellow arrowheads) surrounding the hair follicles (asterisk) at the dermoepidermal junction level. B, An RCM close-upat the superficial dermis level shows that some of the hair follicles (asterisk) had proliferations of strands of pigmented keratinocytes (red arrowheads) and atypical round and dendritic large cells (yellow arrowheads). C, En face histopathologic section showing a hair follicle with an increased number of melanocytes (yellow arrowheads) and radial rete ridge projections with pigmented keratinocytes (red arrowheads); this image correlated with the RCM image shown in panel B (hematoxylin-eosin). D, Vertical histopathologic section showing an increased number of junctional melanocytes surrounding a hair follicle (yellow arrowheads) and a proliferation of strands of keratinocytes arising from the hair follicle (red arrowheads) (hematoxylin-eosin).
