haemangioma
Very LowTechnical/Medical
Definition
Meaning
A benign tumour or growth, typically present at or shortly after birth, made up of a mass of newly formed blood vessels.
In medical terminology, a type of vascular anomaly, often appearing as a red or purple birthmark on the skin or within internal organs. It is not a cancer but a cluster of extra blood vessels.
Linguistics
Semantic Notes
The term is a compound of 'haem-' (blood) and 'angioma' (tumour of vessels). It is a highly domain-specific word, rarely used outside medical contexts.
Dialectal Variation
British vs American Usage
Differences
The primary difference is in spelling: British English uses 'haemangioma' (haem-), while American English uses 'hemangioma' (hem-). There are no semantic or usage differences beyond this.
Connotations
None; purely technical in both varieties.
Frequency
Equally rare in both varieties, used exclusively in medical fields.

Mnemonic
Think: HAEM (like in haemoglobin, for blood) + ANGIO (vessel) + OMA (tumour) = a tumour of blood vessels.
Conceptual Metaphor
A berry or a strawberry (for the common infantile type, often called a 'strawberry naevus').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct translation might lead to гемангиома, which is correct. The trap is misinterpreting the '-oma' suffix as always meaning 'cancer', when it denotes a benign growth in this context.
- Confusing it with other vascular terms like telangiectasia (dilated vessels) or lymphangioma (lymph vessel tumour).
Common Mistakes
- Spelling: mixing 'haem-'/'hem-'; confusing 'haemangioma' with 'haemorrhage'.
- Pronunciation: stressing the wrong syllable (e.g., /ˈhiːmæn.../ instead of /hiːˌmæn.../).
- Overgeneralising the term to any red skin mark.

Frequently Asked Questions
No, a haemangioma is a benign (non-cancerous) growth of blood vessels.
No, many small, uncomplicated haemangiomas, especially in infants, regress spontaneously and only require observation.
The exact cause is unknown, but it is related to the abnormal proliferation of cells that line blood vessels (endothelial cells). Most are not inherited.
'Angioma' is a broader term for any benign tumour of blood or lymph vessels. 'Haemangioma' specifies that the tumour is composed of blood vessels.
