Clinical featuresThis section has been translated automatically.
Mostly solitary, 0.2-0.5 cm in Ø, red to brown-red papule/plaque, which in some cases (about 20%) is surrounded by a narrow pale halo and a larger brownish ring (shooting disc aspect). This halo may fade or recede with time. Spontaneous regression of the hemangioma is not uncommon. 'Target-like' hemangioma.
Shallow dark brown variants may lack cocard stratification, causing them to be misrecognized as melanocytic neoplasms.
HistologyThis section has been translated automatically.
- Superficial dermis: dilated, lacunar, thin-walled vessels lined by prominent "hobnail" endothelia, few intraluminal erythrocytes. Erythrocyte extravasations and hemosiderin deposits are frequently present (see below clinic).
- Deep dermis: slit-like vascular spaces and haemosiderin deposits located between compressed collagen bundles Smooth muscle actin-positive pericytes are missing (indication of lymphatic differentiation). No mitoses or nuclear atypia.
