Low-magnification histologic view reveals some hyperkeratosis and acanthosis with rete ridges surrounding dilated vascular channels in the papillary dermis.
-
This mid-power histologic view reveals dilated vessels in the papillary and upper reticular dermis. The vessels are packed with red blood cells; this finding is suggestive of vessel thrombosis.

This high-power histologic view reveals some hyperkeratosis and acanthosis with rete ridges surrounding dilated vascular channels in the papillary dermis. Dilated vessels in the papillary and upper reticular dermis are observed. The vessels are packed with red blood cells; this finding is suggestive of vessel thrombosis. A normal-appearing vascular endothelium is found. No evidence of a melanocytic lesion is present.
