Acquired Tufted Angioma at Scanning Magnification Scanning magnification of acquired tufted angioma (ATA) shows scattered lobular collections of vessels 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 Vessels Higher magnification of ATA shows a lobular cluster of blood vessels lined by small, oval to spindle-shaped cells. Lumina are collapsed and slit-like .
Acquired Tufted Angioma at High Magnification High-power view shows bland cytologic features of the tufted angioma endothelial cells. Some of the cells show mild nuclear hyperchromasia , but no significant cytologic atypia is identified.
Acquired Tufted Angioma at Low Magnification Scanning magnification of another ATA shows scattered dermal lobular collections of vessels. The lobules bulge into dilated vessels, with a few peripheral semilunar spaces identified .
