Cutaneous epithelioid angiomatous nodule: a case series and proposed classification.
Cutaneous epithelioid angiomatous nodule is a peculiar and recently recognized vascular proliferation. Clinically, these lesions affect different areas of the body and histologically are characterized by a well-circumscribed, mainly unilobular, solid proliferation of endothelial cells with prominent epithelioid features. The cytoplasm is abundant and eosinophilic, and many of the neoplastic cells contain prominent vacuoles. Inflammatory infiltrates are variable. All the cases reported thus far have followed a benign course. We report 10 additional cases of this curious entity, including 2 which presented in an eruptive fashion and 5 that were located on the head and neck. We also discuss the histological differential diagnoses with other epithelioid proliferations and propose categorization within the spectrum of epithelioid hemangioma.
