“…Three main patterns have been reported, i.e., “mosaic” (relatively flattened and rounded structures, which are similar in diameter and resemble a jigsaw puzzle among each other), “knob-like” (short and closely aggregated knob-like projections, which are similar in both diameter and length among each other), and “finger-like” (relatively long, usually markedly separated finger-like projections, which are similar in diameter but different in length among each other) [ 2 , 6 , 51 – 61 ]. A combination of such patterns and unspecific presentations (not classifiable according to the previous three patterns) may also be observed [ 2 , 51 – 58 ]. Several vascular structures can be observed in anogenital warts, including dotted and glomerular, looped, coiled, comma, and hairpin vessels [ 2 , 6 , 51 – 61 ].…”
