A, Fluorescence confocal microscopy mosaic reveals a well-defined cutaneous squamous cell carcinoma silhouette with sharp demarcation and highly fluorescent areas (scale bar = 750 μm). B, Corresponding histopathologic images showing a well-differentiated tumor. C, Detail of the tumor showing keratin pearls (red arrows; scale bar = 150 μm). D, Histologic evaluation reveals the presence of several keratin pearls (red arrows). E, Fluorescence confocal microscopy overview of the tumor reveals a poorly defined tumor silhouette with a highly fluorescent area in the upper portion and lower fluorescence in the deepest part of the tissue corresponding to the infiltrative area (scale bar = 750 μm). F, Corresponding histopathologic image reveals a poorly differentiated tumor with irregular epithelial tongues. G, Few keratin pearls (red arrow) can be detected along with infiltrative cords of poorly differentiated keratinocytes (blue arrow; scale bar = 150 μm). H, Histopathologic image shows a poorly differentiated tumor with few keratin pearls (red arrow) and infiltrative cords (blue arrow).
