Diffuse dermal angiomatosis (DDA) is a benign vascular condition presenting as skin plaques. Early treatment of underlying peripheral vascular disease can promote DDA resolution.

Area of Science:

Dermatology
Vascular Biology
Pathology

Background:

Diffuse dermal angiomatosis (DDA) is an acquired vascular proliferation.
Clinically, DDA presents as violaceous, livedoid plaques with ulceration.
Histology shows interstitial CD31-positive endothelial cells without atypia or vasculitis.

Observation:

A case of DDA in a 53-year-old man with peripheral vascular atherosclerosis is presented.
The patient's DDA resolved after undergoing revascularization procedures.
This suggests a link between DDA and ischemic peripheral vascular disease.

Findings:

DDA is characterized by a diffuse proliferation of endothelial cells in the dermis.
The condition lacks features of malignancy or vasculitis.

Resolution of DDA was observed following treatment for peripheral vascular disease.

Implications:

Peripheral vascular atherosclerosis may be an underlying cause of DDA.
Revascularization can effectively treat DDA in patients with ischemic vascular disease.
This finding highlights the importance of addressing underlying vascular pathology for DDA management.
