Hemangioma is a very common benign vascular tumour.
Hemangiomas of the liver are dealt with in the article liver hemangioma.
Anastomosing hemangioma is dealt with in the article anastomosing hemangioma.
General
Hemangiomas to remember - if you're only going remember a few:
- Glomeruloid, infantile, cavernous, capillary, arteriovenous, venous and intramuscular.
- ICD-O: 9120/0.
Childhood
Common childhood hemangiomas:[1]
- Tufted - small clusters of blood vessels.
- Microvenular hemangioma.
- Glomeruloid hemangioma - associated with POEMS syndrome, Castleman disease.[2][3]
- Epithelioid hemangioma - see angiolymphoid hyperplasia with eosinophilia.
- Targetoid hemosideric hemangioma.
- Infantile hemangioma (AKA juvenile hemangioma[4]) - these tumours are GLUT-1 +ve. They tumours grow and then spontaneously regress.[5]
Soft tissue
Several types are seen in soft tissue:[6]
- Capillary.
- Cavernous.
- Arteriovenous.
- Venous.
- Intramuscular.
- Synovial.
CNS
Usually from bone, rarely dural and parenchymal hemangiomas.
- Cavernous.
- Capillary.
Microscopic
Features:
- Channels lined by benign endothelium containing RBCs.
DDx:
- Lymphangioma.
- Angiokeratoma.
- Lobular capillary hemangioma (pyogenic granuloma).

IHC
- CD31 +ve.
- D2-40 -ve.[7]
Juvenile hemangioma:[4]
- GLUT-1 +ve.
Sign out
Subcutaneous Neck Lesion, Left, Excision: - Cavernous hemangioma. - NEGATIVE for malignancy.
Block letters
SUBCUTANEOUS NECK LESION, LEFT, EXCISION: - CAVERNOUS HEMANGIOMA. - NEGATIVE FOR MALIGNANCY.
LESION, LEFT SIDE OF FACE, EXCISION: - CAPILLARY HEMANGIOMA. - NEGATIVE FOR MALIGNANCY.
Micro - skin
The sections show hair-bearing skin with abundant small superficial vascular channels containing red blood cells. The endothelial cells of the vascular channels do not have atypia. No mitotic activity is appreciated. The overlying epidermis is unremarkable. Extensive solar elastosis is present. No nevus is identified.

- Vascular tumours.
- Pneumocytoma - previously known as sclerosing hemangioma.
