Diffuse Dermal Angiomatosis of the Breast: A Distinct Entity in the Spectrum of Cutaneous Reactive Angiomatoses - Clinicopathologic Study of Two Cases and Comprehensive Review of the Literature

Diffuse Dermal Angiomatosis of the Breast

Diffuse dermal angiomatosis (DDA) is a rare, benign cutaneous disorder that can affect the breasts. Typically, it presents in middle-aged women and is increasingly associated with various risk factors that involve tissue hypoxia. We report this case of classical bilateral DDA of the breasts in a 56-year-old female patient. This case highlights the association of DDA with hypoxia-inducing risk factors, such as smoking. Management of the hypoxic risk factors resulted in the resolution of the bilateral ulceration caused by DDA in this patient. This case report aims to discuss the etiology, risk factors, clinical manifestations, and treatment modalities commonly used to manage this condition.

Diffuse dermal angiomatosis of the breast: a case report of successful treatment with topical propranolol

We present a notable case of diffuse dermal angiomatosis of the breast (DDAB) in a 92-year-old woman with multiple comorbidities. The patient exhibited rapid and nearly complete resolution of lesions following early topical application of 1% propranolol in cold cream highlighting its potential as an effective treatment option for DDAB.

Diffuse dermal angiomatosis of the breast: an emerging entity in the setting of cutaneous reactive angiomatoses

New and emerging types of cutaneous vascular (capillary) proliferations have been described or better categorized in the last few years. They include reactive angioendotheliomatosis, acroangiodermatitis (pseudo-Kaposi sarcoma), diffuse dermal angiomatosis, intravascular histiocytosis, glomeruloid angioendotheliomatosis, and angiopericytomatosis (angiomatosis with cryoproteins). Clinically, they are characterized by multiple, red violaceous, and purpuric patches and plaques, sometimes evolving toward necrosis and ulceration with a wide distribution but a propensity to involve the extremities. Histologically, they are characterized by different patterns of intravascular or extravascular lobular or diffuse hyperplasia of endothelial cells, pericytes, and sometimes histiocytes. Although these angioproliferations can histologically have a pseudoangiosarcomatous pattern, they are reactive in that they originate from the (sub)occlusion of vascular lumina by different localized or systemic disorders. The vascular proliferation stops after the inducing hypoxic stimulus has been withdrawn. Among them, diffuse dermal angiomatosis of the breast is a variant of diffuse dermal angiomatosis involving middle-aged women with macromastia, obesity, smoking, and vasculopathic disorders, considered a distinct disorder in the spectrum of cutaneous reactive angiomatoses. It presents with reticulated erythematous to purple patches with sometimes a tendency to ulcerate and bleeding, appearing on large, pendulous breasts. The pathogenesis is related to tissue hypoxemia resulting from subclinical torsion, compression, and increased venous hydrostatic pressure due to the macromastia, aggravated by the associated ischemic conditions such as hypertension and diabetes. There is no evidence-based therapy, but reduction mammoplasty is a viable treatment option. This should be evaluated in all patients who fail conservative therapy.

Diffuse dermal angiomatosis of the breast

Diffuse dermal angiomatosis of the breast can be a painful, irritating, and persistent inflammatory condition. It tends to present in middle age and is associated with a number of risk factors, mainly relating to tissue hypoxia. There are no standard treatment guidelines, and current treatment focuses on mitigating tissue hypoxia by addressing atherosclerosis through lifestyle changes and medical and/or surgical intervention. Herein, we present a case of diffuse dermal angiomatosis of the breast, describing the condition and current treatment approaches and the likelihood that this diagnosis is more common than previously believed.
