Contributed by Dr. Mark R. Wick:

Epithelioid

Lobular capillary

Tufted

Venous



Angiomatosis:

Dilated vascular channels in breast tissue

Anastomosing
vascular channels,
flat endothelial cells,
no smooth muscle



Atypical hemangioma:

Cavernous vessels infiltrating into fat

Branching
vascular channels
lined by bland
endothelium

Cavernous
hemangioma above
and branching vascular
channels below



Capillary hemangioma:

Thin walled vessels of various sizes with
bland endothelium and complex branching
vessels are suggestive of granuloma
pyogenicum but without inflammation



Cavernous hemangioma:

Well circumscribed with dilated vascular channels, lobular-like pattern of dilated vessels but no anastomosing channel, vascular spaces are lined by inconspicuous endothelium; organizing clot with recanalization, no / rare Ki67 staining



Perilobular hemangioma:

Lesion in stroma is not lobules or ducts

Thin walled vessels
are congested
and extend into
adjacent fat



Atypical perilobular hemangioma:

Inconspicuous slit-like vascular spaces lacking red blood cells

Hyperchromatic endothelial nuclei

Extension into fat
and no distinct
congested
capillary channels

Compact vascular
proliferation
associated with
terminal duct
