(B) In RCM, numerous bulbous projections at the level of DEJ and the so-called cord like appearance are seen. Before These harmless skin barnacles usually begin appearing after age 40 and can show up anywhere on the skin. Also, the vascular pattern typical of SK is made up by hairpin vessels, described as linear looped vessels forming a half-looped or hairpin-like structure. In rare cases, however, a sudden onset of numerous seborrheic keratoses may be linked to underlying malignancy, such as cancer in the gastrointestinal tract, lymphoma, or leukemia. (C) In dermoscopy dotted vessels are visible over the entire lesion area (white arrows). On the other hand, SKs may mimic malignant tumors, especially those hyper pigmented, reticular and irritated (Figure 12). False positive and false negative cases are not exceptional.
