This article covers soft tissue vascular tumours. Vascular malformations are covered in the vascular malformations article.
Normal histology
Normal blood vessel histology is dealt with in the vascular disease article.
Mimics
Distinct entities
Hemangioma
Main article: Hemangioma
Main article: Liver hemangioma
Lymphangioma
General
- Benign.
- Classically in the left neck.[1]
- May be seen in Turner syndrome.
Treatment:
- Surgical excision.
Microscopic
