Angiomas and hemangiomas are both benign growths that appear on the skin, but they have different compositions and characteristics.
Angioma:
- Angiomas are benign growths made of blood vessels or lymphatic vessels, arranged in an abnormal pattern.
- They can occur in early life or later in life.
- Cherry angiomas, the most common type of angioma, are small papular angiomas and are true capillary hemangiomas.
- Angiomas are usually painless, purple or red in color, and typically found on the skin.
Hemangioma:
- Hemangiomas are small growths made of blood vessels only.
- They can appear in early infancy through childhood.
- Hemangiomas are the most common benign (noncancerous) tumor of the skin.
- They may be present at birth (faint red mark) or may appear in the first months after birth.
- Hemangiomas are also known as port wine stains, strawberry hemangiomas, and salmon patches.
In summary, the main difference between an angioma and a hemangioma is that an angioma is a benign growth made of blood vessels or lymphatic vessels, while a hemangioma is a small growth made of blood vessels only. Both are generally harmless and benign, but they can have different appearances and occur at different stages of life.
Comparative Table: Angioma vs Hemangioma
Here is a table comparing the differences between angiomas and hemangiomas:
Feature | Angioma | Hemangioma |
---|---|---|
Definition | Angioma is a benign tumor formed by the dilation of blood vessels or the formation of new ones by the proliferation of endothelial cells. | Hemangioma is a true neoplasm of endothelial cells and should be differentiated from vascular malformations, which are localized defects of vascular morphogenesis. |
Growth | Angiomas can grow by endothelial cell hyperplasia. | Hemangiomas grow by endothelial cell hyperplasia and should be differentiated from vascular malformations, which are not true neoplasms but are localized defects of vascular morphogenesis. |
Appearance | Infantile hemangiomas are present at birth, slow growing, infiltrative, and destructive. Congenital hemangiomas either rapidly involute (rapidly involuting congenital hemangioma) or persist (non-involuting congenital hemangioma). | Hemangiomas are the most common vascular tumor and are further categorized into two types: "infantile" or "congenital". |
Types | There are various types of angiomas, including cavernous hemangiomas (telmangiectasias), venous malformations, lymphatic malformations, and arteriovenous malformations. | Hemangiomas can be classified as "infantile" or "congenital". |
Please note that the terms "angioma" and "hemangioma" are sometimes used interchangeably, and the differences between them can be unclear even in the scientific literature.
