Diffuse dermal angiomatosis (DDA) is a benign vascular proliferation. A case report details a rapidly growing DDA lesion that spontaneously resolved within 12 weeks.

Area of Science:

Dermatology
Vascular Biology
Pathology

Background:

Diffuse dermal angiomatosis (DDA) is an acquired vascular proliferation.
It presents as painful, livid-erythematous plaques with potential ulceration.
Histology shows a dense network of regular capillaries without atypia or vasculitis.

Observation:

A 43-year-old woman presented with a rapidly growing, unusual DDA lesion.
The lesion appeared 8 cm above a surgical scar after significant weight loss (20 kg).
The lesion was brownish-livid in appearance.

Findings:

The DDA lesion demonstrated spontaneous regression within 12 weeks.
No recurrence was observed during a 4-year follow-up period.
Histological examination confirmed DDA without signs of malignancy or vasculitis.

Implications:

This case highlights the benign and self-limiting nature of some DDA presentations.
It suggests a potential association between DDA and significant physiological changes like rapid weight loss.
Further research may elucidate the specific triggers and prognostic factors for DDA.
