Tufted Angioma

Acquired Tufted Angioma at Scanning MagnificationScanning magnification of acquired tufted angioma (ATA) shows scattered lobular collections of vessels image in the superficial and deep dermis. The lobules bulge into dilated vessels, with a few peripheral semilunar spaces identified.

Acquired Tufted Angioma: Lobular Cluster of VesselsHigher magnification of ATA shows a lobular cluster of blood vessels lined by small, oval to spindle-shaped cells. Lumina are collapsed and slit-like image.
image
Acquired Tufted Angioma at High MagnificationHigh-power view shows bland cytologic features of the tufted angioma endothelial cells. Some of the cells show mild nuclear hyperchromasia image, but no significant cytologic atypia is identified.

Acquired Tufted Angioma at Low MagnificationScanning magnification of another ATA shows scattered dermal lobular collections of vessels. The lobules bulge into dilated vessels, with a few peripheral semilunar spaces identified image.
