Campbell de Morgan Spots (Cherry Angiomas) Show Endothelial Proliferation

Campbell de Morgan spots (also known as adult hemangiomas, cherry angiomas, or senile angiomas) show clinical and histopathological features that make them distinct. Despite this, they are not included as benign vascular tumors in the current classification by the International Society for Vascular Anomalies (ISSVA). In the current study, we investigated the proliferation rate (Ki67) of the endothelia of 23 cases of Campbell de Morgan spots, as well as the immunoexpression of Wilms tumor protein 1 (WT1) by these vascular anomalies. The youngest patient was 24 years old (range: 24-80; mean: 52.61). Ten patients were women (43.48%). All cases showed intense cytoplasmic expression of WT1 by the endothelia in 80%-100% of the endothelial cells. Ki67 demonstrated proliferation by the endothelia of all vascular lesions. A mean of 1077.6 nuclei were evaluated per case. Eight cases showed a very low proliferation (less than 0.5% of the nuclei). In the other 15 cases, the proliferation ranged from 0.59% to 3.59% (mean: 1.89%).
