Abstract:
Objective:To investigate the significance of lymphatic markers in the differential diagnosis of angiokeratoma corporis diffusum (ACD) and angioma serpiginosum (AS) .
Methods:Totally, 9 patients with ACD and 6 with AS were enrolled from Department of Dermatology, Xijing Hospital between 2006 and 2017, and their clinical and histopathological features were retrospectively analyzed. Skin sections from all the patients were stained for CD31, D2-40 and Prox1.
Results:In the 9 patients with ACD, abnormal vessels were weakly positive or negative for CD31, and positive for Prox1. Endothelial cells in abnormal vessels were locally positive for D2-40 in 4 patients with ACD, but negative for D2-40 in the other 5 patients. In the 6 patients with AS, the endothelia of hyperplastic small vessels were positive for CD31, but negative for D2-40 and Prox1.
Conclusion:The clinical features of a few patients with ACD are similar to those of patients with AS, and lymphatic markers have definite significance in the differential diagnosis of the two diseases.
