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]

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.

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.
