Diffuse dermal angiomatosis localized to abdominal striae.

Area of Science:

• Dermatology
• Pathology
• Vascular Biology

Background:

• Diffuse dermal angiomatosis (DDA) is a rare, benign, reactive cutaneous vascular proliferation.
• It is considered a distinct variant of reactive angioendotheliomatosis.
• DDA typically affects obese individuals with risk factors for atherosclerosis and hypoxemia.

Observation:

• A case report of a 40-year-old woman with ulcerated abdominal plaques is presented.
• Histopathological evaluation confirmed the diagnosis of diffuse dermal angiomatosis.
• Notably, the lesions were localized to the patient's abdominal striae.

Findings:

• The patient's presentation of diffuse dermal angiomatosis was unique due to the specific localization to abdominal striae.
• This finding expands the known clinical spectrum of DDA presentation.
• Histopathology confirmed the characteristic vascular changes of DDA.

Implications:

• This case broadens the understanding of diffuse dermal angiomatosis presentation.
• It suggests that striae may serve as a predilection site for DDA development.
• Further research may elucidate the pathomechanisms underlying DDA in specific anatomical locations.
